Strive for the Breaking-in Period of mining machinery to anticipate the bright future
At present, China mining machinery industry has stepped into the rank of
international market, and the development scope is obvious. But so far, there is
still a breaking-in period in mining machinery industry. What is breaking-in
period inf the field?
Breaking-in period is a personal experience almost everyone has gone through.
There is no exception, it is also the same with machine, especially mining
machinery. About this period, there is some features.
1. Seepage
Due to parts' looseness, or influenced by vibration and temperature, there
will be seepage in machine' s sealing surface, pipe joint, etc. Some flawed
processing technics may not be found during assembling and trial operation, and
when in operation, these flaw will be gradually exposed by vibration and impact
force, taking the form of water or oil leak. So it is very common during
running-in period.
2. Looseness
Newly processed parts may have some deviation in geometric shape and fittig
size. During the primary period of using, vibration, impact , temperature,
distortion, all these factors with later abrasion will make machine parts
loose.
3. Poor Lubrication
As the fit clearance of newly assembled parts is relatively small, so it's
hard to guarantee its even distribution, leading to the difficulty of forming
even oil film in friction surface. Low effect of lubrication will make mining
machine's abnomral abrasion in the early stages or even worse cause
malfunction.
4. Operation Mistake
For operators who dont know enough about machine structure and formance,
especially new operators , malfunction caused by operation mistake is very easy
to occur.
Sustaintial and stable development will take a transition period or
breaking-in period. With the period, any detail will bring great profit or even
great loss. Especially for mining machiner industry - the leading heavy
industry, we'd better pay more attentions and energies to keep and extend
it.
New service for mining wear parts with new features and nice management
Mining wear parts are not all about durability and materials. Many suppliers
are keen to emphasize how the parts are compatible or reliable. Imagine
purchasing new mining wear parts but your employees are having difficulty
embracing new features or they are not maintaining the wear part according to
the supplier's recommendations. This may be a situation where a training session
can educate employees about the new mining equipment parts and they can better
understand the maintenance schedule. A supplier that offers training programs is
one that is in-tune with their clients. Training sessions can help improve
workplace safety and aid in a seamless transition to working with new parts.
Supervision and maintenance of mining OEM replacement parts is another
service that suppliers frequently offer. This means that the purchaser contracts
out the inspection and maintenance of the parts. This service can greatly
benefit a company, as it means the worksite will regularly have experts with the
latest knowledge checking the equipment. Common sense tells us that regular
maintenance improves productivity and performance. Having mining wear parts
experts perform this service only enhances the process. They can quickly perform
maintenance on-site and help the organization identify problem areas before they
become large repairs.
Another key service to investigate is how repairs are handled. When it comes
to any mining parts, they will eventually need repairs, need to be retrofitted,
or perhaps completely re-built. Finding a supplier that offers these services is
a cost-effective solution to handling failing equipment. The expense is far less
than buying new or refurbished equipment. Such a service can quickly restore
equipment so down time is kept to a minimum.
There are times, however, when mining wear parts simply need replacing. This
is a service that may seem obvious but should still be investigated. Can the
supplier quickly replace the wear part that they previously sold to the company?
What are the delivery timelines? Are they able to accommodate international
delivery? A supplier should be able to adequately outline their replacement
service. The way a supplier handles repairs heavily influences a purchaser's
business.
Finally, one of the most sought after services for purchasers of replacement
OEM mining parts is the possibility of engineered-to-order (ETO) parts. These
are essentially custom-made mining parts, designed to accommodate new or older
equipment. A supplier must have a thorough knowledge of previous designs and
specifications so that they can adapt parts to different equipment. This
expertise and experience is an essential service.
As important as the mining wear part is, the services offered by the supplier
are just as integral to the relationship between the purchaser and supplier.
Before buying wear parts, be sure to research the services provided.
Shock tactics on Greener Environment and Energy-Saving Move

equipment of interest are as industry scale and technology progress and falling
rapidly. Interest rate cuts mining investors are more willing to purchase
affordable, quality reliable environmental protection and energy saving
equipment production as the device of choice. Based on this, environmental
protection and energy saving equipment increasingly show cost advantage.
New year has a new start; New times needs new leadership style
If roll along the length direction feeding not even, roller surface not only
faster, and each point wear is uneven and will appear ring groove, the normal
work have been destroyed and broken the uneven size products. Therefore, in
addition to crushing the roll crusher, outside of finely roll crusher, usually a
feeder, to ensure that the feeding successive and even, and the length of the
feeder with roller length equal, makes the feeding length direction along the
roller uniform. In order to ensure the maximum efficiency of hammer crusher, charging must
continuously even distribution of the rolls.
We should be regularly check whether the material mouth had blocked
phenomenon, and in the motor stopped working to stop before feeding, when
material completely dropped, the roll of a power outage, motivation may idling.
And roller, the reasonable maintenance and correct crusher of operation, can
ensure long-term continuous work, reduce stop time, only normal management and
every day to check the normal work of the roll crusher, to prevent failure, and
ensure that the work continuously. Therefore, the operator should pay attention
to the following items:
(a) Pay attention to all parts, such as the discovery of bolts shall be
immediately screw loose;
(b) Before work must first start roll crusher, wait for after normal speed,
again to machines feeding, when parking program instead;
(c) Check the material regularly, such as the discovery of a mouth clogged,
should be cleared;
(d) Check the vulnerable parts wear degree, always be worn parts; replace
(e) Not make machines produced load, should always be electric
instrument;
(f) bear oiling in time, do not make in the place of oil bearing;
(g) Be controlled bearing temperature, may not be higher than the air
temperature around 25 to 30 ;
(h) put the plane, chassis activities device should remove dust and material,
so as not to roll crusher met and cant broken material, activity in the chassis
not bearing mobile, down to produces serious accident.
Henan Hongxing Mining Machinery Co., Ltd, in order to promote the competitive
strength, the advanced technologies have been introduced from America, Germany,
Japan and Australia, which established the international advanced production
line, first-class modern testing base as well as research centers of sand maker, mill and
mine-selecting equipment. Scientific management, advanced processing technology
and innovative manufacturing theory make the company become the mining machinery
manufacturing and exporting base in China.
A modern day gold panning is underway. With prices at an all time high more
and more gold prospecting are heading into the mining fields of Arizona, Nevada,
California, New Mexico, Alaska and many other places across the U.S. and other
gold bearing areas of the earth. In the mining and prospecting world you can now
routinely hear of men and women gold seekers spending thousands of dollars on
prospecting equipment they have never used, having no experience finding gold
and buying worthless mining claims with hopes of striking it rich. Those who are
mining the miners are in the real.
Recreational gold mining and prospecting has become a popular outdoor
recreation in a number of countries, including New Zealand (especially in
Otago), Australia, South Africa, Wales (at Dolaucothi and in Gwynedd), in Canada
and in the United States especially in western states but also elsewhere.
Recreational gold mining is almost entirely small-scale placer mining.
Gold trommel is the mining of alluvial deposits (deposits of sand and gravel
in modern or ancient stream beds) for minerals. This may be done by open-pit
(also called open-cast mining) or by various forms of tunneling into ancient
riverbeds. Excavation may be accomplished using water pressure (hydraulic
mining), surface excavating equipment or tunneling equipment.
Gold mining and prospecting activities allowed on public lands vary with the
agency and the location. Gold pans and shovels are commonly allowed, but sluice
boxes and suction dredges may be prohibited in some areas. The Department of
Agriculture in the U.S. is now of the view that recreational gold panning and
gold prospecting in national forests is permitted provided that no machinery or
explosives are used, no waterways are diverted, and no permanent or
semi-permanent structures are built. There are public mining areas in many
states, and prospecting may allow one to stake a gold placer claim or other type
of gold mining claim in certain areas. Some public lands have been set aside for
recreational gold panning. Some private land owners also give permission for
small-scale gold mining.
The beauty of this new rush is we get to experience it and see the successes
and failures as they unfold in the fields. Gold Mining and prospecting equipment
sales are at an all time high, advertising in gold prospecting and mining
magazines is being sold at premium prices and the BLM is processing more gold
claims than any time in the last 20 years.Metal detectors costing $4,000.00 plus
designed for gold are selling like gold pans in the days of the gold rush of the
1800s. This is a very exciting time to be a gold prospector.
Green Industry, Green Industry. Why Green Industry, Green Products?
More businesses are turning to green cleaning services over traditional
chemical cleaning services. Read on to determine if green cleaning is right for
your business and find out how green cleaning holds up to traditional
methods.
When you use chemical cleaning products regularly, you often forget how
dangerous they are. By using chemical cleaning products, you are not only
harming the environment, but also your health.
Several cleaning products are classified as corrosive. These are the
chemicals that cause damage to organic material, particularly human flesh. When
cleaning, you are using chemicals to clean away the dirt and grime. The more
effective a chemical is in cleaning away dirt, the more damaging it will be to
your skin. If it accidentally splashes in your eyes, it will do even more
damage.
No matter how safely you use chemicals, how they are stored and how well we
stick to the manufacturers guidelines, the reality is they still affect our
environment. Many people release chemicals into storm drains, meant for removing
excess water after a downpour. This has an extremely negative impact on our
environment. Several cleaners release pollutants in the air, and the poisonous
effect of these pollutants severely harms animal and plant life.
The only way to fight against polluting the environment is to seek safer
alternatives for cleaning commercial facilities. Choosing products that have
environmental attributes such as biodegradability, low toxicity, low volatile
organic compound (VOC) content, and low life cycle energy use will minimize the
effect on our atmosphere. It will help improve air quality and reduce water
pollution, thus making our quality of life better.
The widespread popularity of green cleaning products with environmental
agencies indicates that these are effective. Agencies such as EcoLogo and Green
Seal certify products for efficiency, in addition to their health and
environmental benefit. As for the costs, prices of green products have come down
steadily in recent years. Moreover, usage of green products offers some
ancillary benefits as well. Insurance companies may lower the premium for
enterprises using green cleaning products. Recent studies also indicate that the
use of these products boosts productivity.

Rotary dryer is
used to dry and dehydrate the materials with high water content, which plays an
important role in modern industrial area. It can make the waste sludge into
usable resources and save energy conservation to achieve the sustainable
development of scientific strategy concept with good economic and social
benefits.
We have explained you some basic knowledge of rotary dryer in the news we
published before. How to improve the drying capacity of rotary dryer is our
customers primary concern. Here we would like to share you the temperature of
hot air affects the production capacity of rotary dryer. Drying capacity is
affected by air temperature more seriously.
When choosing the drying equipment, we should be sure to have good
understanding of material limit temperature. Once the material allows, we should
try to choose high-temperature media.
Particularly, there are many types of drying methods, especially the fast
drying. The material temperature after drying is beyond the medium temperature
significantly. For example, the air temperature of air dryer is up to 250 or
more, while the discharged temperature is generally below 60.Henan Hongxing

Learning about the related contents of Equipment Appraisal Business
Whenever establishing the property value of equipment, whether or not for
farm equipment, manufacturer equipment, restaurant equipment appraisal or
machinery appraisal, the appraisal business will need to take on one of three
methods. The actual method to be used depends upon readily available data, the
condition of the machinery and the business asset which is getting the
appraisal.
The 3 old-fashioned strategies to establish the property value of anything
are: Cost Approach; Sales Approach; Sales Comparison Approach.
The Cost Approach compares the price tag to restore the machinery or
equipment then taking away the level of wear to the item. This method considers
various factors; what was the price of the machinery when bought new from the
factory, precisely what the valuation on the particular equipment is these days
if purchased new and also the estimated expense to refurbish the machine to be
regarded as totally refurbished.
The Sales Approach is also known as the Market Approach. The Sales Approach
may be the more widely known strategy to appraising machinery and equipment.
Real Estate appraisers make use of this method to establish value on a
household. The Sales Approach works very well for machinery appraisals because
marketplace info is readily obtainable and also reliable.
The Sales Comparison Approach to valuation compares the sales of other
equivalent machinery or equipment within equipment auctions, classified prices
and other known marketplace valuations. Using the knowledge of the market
industry the appraisal company is likely to make adjustments to the worth of the
machinery that indicate the equipments age and condition.
To determine replacement prices the appraiser will most likely choose the
manufacture and other prices lists. The actual replacement price is the cost to
replace the equipment completely.
Devaluation aspects can be determined by just how much wear and tear the
equipment has on it, as well as by obsolescence. Devaluation variables also are
influenced by life expectancy, its age, and also the equipments functional
status or utility. Some other depreciation variables will be affected through
things such as regulatory concerns, monetary penalties, as well as supply and
demand.
Yet another approach that is less frequently utilized is the Income Approach.
The Income Approach calculates the amount of cash flow that a piece of machinery
could very well generate if totally functional. These statistics can be
extremely hard to exactly figure out because possible revenues vary so
significantly.
Most equipment appraisal companies use a mix of all these techniques to
decide equipment value. With the use of a number of techniques the professional
appraiser is able to help support the valuation of the equipment they are
appraising.
To find out more about the appraisal business and how to evaluate equipment
make sure you be sure to look at all of my many other content articles about the
appraisal business.
Count on the important role of steel rolling mill equipment
As many things are going very fast in today's changing world. So, we have to
be prepared for all those changes. Technology is one of those things which is
going a rapid change from a few couple of years. People are becoming familiar
with the machines. Different types of machines are used by different groups for
different purpose. Here, we will make discussions about steel rolling mill
machinery.
This machine is used in factories for preparing metal sheets. Before moving
ahead, you must know what metal is? Well metal is an electropositive element
having shiny surface and is good conductors of heat and electricity and can be
melted or fused into any shape you want by heating it on a high temperature.
Metal sheets are made by passing the material between the rollers. It is used
for different purposes such as nail making, metal or steel sheets. This machine
is categorized into two parts: hot rolling mill and cold rolling mill.
If the temperature of the metal is above than its recrystallization
temperature then it is termed as hot rolling process. If the temperature of the
metal is below than its recrystallization temperature then it is termed as cool
rolling process. In hot rolling mill, a large piece of metal is heated above
their temperature and then deformed between rollers. Cold steel rolling mill
machinery can be used for all types of heavy mechanical engineering
equipments.
Rolling process is one of different types which include flat rolling, foil
rolling, ring rolling, roll bending, roll forming, and profile rolling, etc.
Flat rolling is a process in which a material having a rectangular cross section
is fed between the rollers which results in metal sheets. Float rolling process
is used for producing foils. In this process, rolling is done by cluster mill
because small thickness requires a small diameter rolls. Ring rolling process is
a special type of process that increases the diameter of the ring. Roll bending
process produces cylindrical shaped products. Roll forming process is used for
producing mechanical parts with long length or heavy quantity. There are many
other methods of making metal sheets and other metallic instruments with the
help of steel rolling mill machine.

other mechanical equipments, and machinery.
When people come across the phrase machinery used', they think that someone
is offering redundant machinery. Many people also believe that such machinery
can lead to wastage of money. Lately, things have begun to change. Nowadays,
people have started investing their money in used items. People now realize that
they can actually save some hard-earned money by buying used items.
Furthermore, this trend has caused a stir. Some experts claim that such items
are useless. On the other hand, many seasoned businessmen say that opting for
used machinery is a good idea. If you've decided to buy any such machine, you
should definitely take care of the following factors:
Options If you come across an advertisement that says Machinery Used',
please cross-check the details of the machinery before buying it. You must take
a closer look at the options. Some of the machines that are commonly available
include fabrication equipment, chip making machinery and support equipment.
However, other options might be available too. Therefore, if you are looking for
air compressors, manual lathes or other such items, this can be prove to be a
really good opportunity for you.
Genuineness This factor is very critical. You must check the genuineness of
the item that you are about to purchase. Supposedly, you are buying an item that
belongs to a specific brand, you should definitely check if that item is
original or not. Used machinery equipment would only serve its purpose if it is
genuine.
Price Of course, this is the most important factor. If some middlemen are
involved, you will get the machinery at a higher price. Do make sure that you
check the price beforehand. This would help you in taking an informed
decision.
Condition At times, you might find such options that are really pathetic.
Needless to say, you should avoid such options. Therefore, it is very important
that you check the condition of the item that has been put up for sale. Talk to
a professional, if you feel that you are not capable enough to determine the
quality on your own.
Credentials of the vendor Whether you buy the machinery from an online
vendor or a typical brick and mortar shop, you must obtain the necessary
information. It is preferable to contact a trustworthy vendor.
New era with new features, New technology with new trends
The development of mining machinery and technological progress of modern
science and technology and is closely related to the overall industrial level,
in particular, mining and mechanical engineering disciplines, science and
development are closely linked. Present is the era of information age, where
information technology has four major characteristics, namely, intelligence,
electronic, global, non-group-oriented. Automated underground mining is no face
or hazardous mining development, but also protect the safety of mining face an
effective way. Forefront of modern science and technology has obvious
time-domain, field and dynamic characteristics. Information science, materials
science, life science, nano science, management science and manufacturing
science is to change the mainstream of 21st century science, and the resulting
high-tech industry will change the world. Cross-integration between the
different sciences will have a new focus on science, economic development and
social progress of mining machinery to generate new demands and
expectations.
Integrated use of mining science, automation technology, communication
technology, computer science and technology, to automate mining face no
fundamental research and development of new technologies, new equipment, mining
machinery will make toward the development of robots and intelligent direction.
Many industries have entered the information, of course, the mining machinery
industry also followed the pace of development of the times, gradually towards
the intelligent direction, so as to keep with international standards, the level
of development and social integration. Mechanical Engineering, the general trend
of scientific development will be digital, intelligent, precision,
miniaturization, and ecological life. Mining machinery as a branch of mechanical
engineering disciplines, but also follow this general trend. Meanwhile, the
mining industry, combined with the characteristics of its development trend is
digital, intelligent, ecological and amenity-oriented. Mining machinery
manufacturing industry should continue into the man's outstanding achievements
in various fields, major demand for national economic construction, scientific
concept of development, achieve sustainable development.
Mining Machinery is a high-tech equipment and integration, the development of
new equipment will continue the integration of human achievement in various
fields to come, as materials science, manufacturing, information technology,
computer technology, each product has a new technology into, parts of the update
cycle is shorter and shorter, faster and faster generation of new equipment,
especially the development of large mining machinery, no mature experience to
draw on, but the design does not allow any mistakes and must therefore be with
the integration of multi-disciplinary technology to improve design efficiency
and design quality, enhance independent innovation capability and market
competitiveness. Mining machinery and computer technology, network technology ,
based on the formation of an integrated digital trends.
Mining machinery manufacturing power towards the journey , the opportunities
and challenges. Product design is the soul of the manufacturing sector, the
product structure, function, quality, cost, delivery time and manufacturability,
maintainability, scrap reprocessing and man, machine and environment
relationship, in principle, are in the product design stage decision. Product
innovation has become a design capacity in the global competition in deciding
the status of the primary factors.
International News on European Stocks future and U.S. Manufacturing development
European stocks rose for a fourth day, with the Stoxx Europe 600 Index headed
for its highest close since August, as a report showed that manufacturing in the
U.S. expanded in December at the fastest pace in six months.
BHP Billiton Ltd. and Rio Tinto Group jumped at least 6 percent, leading
gains by commodity producers as copper increased in London. Automakers rallied
as R.L. Polk & Co. said the number of cars and light trucks sold globally
will grow 6.7 percent this year. Marks & Spencer Group Plc advanced 1.7
percent as Bank of America Corp. upgraded the stock.
The benchmark Stoxx 600 rose 1.3 percent to 250.25 at 3:47 p.m. in London,
heading for its highest close since Aug. 3. The gauge has risen for four days,
its longest winning streak since November. The U.K., the U.S. and Swiss markets
were closed for a holiday yesterday.
'The new year has bearish expectations for growth baked in, providing an
equity-buying opportunity for investors as growth improves later in the year,'
said Daniel Weston, a portfolio adviser at Schroeder Equities GmbH in Munich.
'The market will focus on improving growth increasing profits, low interest
rates benefiting businesses and investors will see equity as a more attractive
alternative than holding cash.'
The Stoxx 600 rallied 1.1 percent yesterday as a measure of German
manufacturing beat estimates. The gauge posted its first yearly decline since
2008 last year as U.S. leaders wrangled over cutting the deficit and euro-area
policy makers remained divided on their response to the sovereign-debt
crisis.
European Budget Rules
National leaders have pledged to draft a stricter rulebook for controlling
government spending. German Chancellor Angela Merkel and French President
Nicolas Sarkozy will meet in Berlin on Jan. 9 to work out the details.
The Institute for Supply Management's factory index rose to 53.9 last month
from 52.7 in November. That beat the median projection of 63 economists surveyed
by Bloomberg News before the report. Fifty is the dividing line between growth
and contraction. Construction spending in the world's largest economy increased
in November, another report today showed.
A separate report on Jan. 6 will probably show that hiring in the U.S.
accelerated in December for a second month, a sign that the country's improving
labor market will bolster consumer spending in early 2012, economists said.
Payrolls climbed by 150,000 workers after rising 120,000 in November, according
to the median forecast of 62 economists in a Bloomberg News survey before the
Labor Department release on Jan. 6.
'U.S. data has continued to impress and markets are expecting the trend to
persist,' Jim Reid, a strategist at Deutsche Bank AG in London, wrote in a
research note today.
European Debt Sales
France sold 84-, 161- and 315-day treasury bills today. The 10-year yield
increased four basis points to 3.28 percent as of 2:05 p.m. London time, rising
for a fifth consecutive day. Two- year yields added two basis points to 0.87
percent.
German unemployment fell in December more than economists had forecast as
exports of cars and machinery boomed and one of the mildest winters on record
helped support jobs in construction.
'The main focus is that there will be no recession,' said Robert Halver, head
of research at Baader Bank AG in Frankfurt. 'It can be a good year for equities
under the condition that European politicians do their homework. The European
Central Bank is in the driving seat.'
National benchmark indexes advanced in 16 of the 18 western-European markets.
Germany's DAX Index added 1.4 percent, while the U.K.'s FTSE 100 Index climbed 2
percent. France's CAC 40 Index gained 0.1 percent.
BHP Billiton, the world's biggest mining company, surged 6.2 percent to
1,993.5 pence, while Rio Tinto, the second- largest, soared 6 percent to 3,313
pence. Copper, tin and zinc advanced on the London Metal Exchange.
Further analysis on stages of Ore crushing and milling process
Crushing and grinding of ore
beneficiation is prepared before the operation. Beneficiation is a
prerequisite to make a useful minerals in the ore reached monomer
separation.
As useful minerals to the single particle size is very small, it is sometimes
necessary to ground ore will be less than 0.074 mm accounted for 80 per cent of
the fine, and even some small way to achieve some useful minerals monomer
Separation.
From stope ore block by the great degree, such as open-pit mining for ore
block of up to about 1000 mm, 1000 mm to large pieces of broken pieces to the
mine only a few dozen microns (1 micron = 1 / 1000 mm), fine-grained, often have
to be completed in several stages.
To broken, in the large-scale plant the general election coarse, medium and
fine three broken (also adopted four paragraphs), the lump ore gradually reduced
to the size of 8-25 mm around, and then sent to the abrasive grinding machine .
Until useful mineral particles to achieve separation of the monomers.
At present, the ore crushing and grinding method primarily with the role of
institutions of the more common mechanical force generally have the following
five.
1. Crushed by two broken face when approaching the squeeze pressure and make
the materials broken.
2. Split broken teeth wedge tip is to use the materials to carry out the
split of the broken, and the role of the concentration of a limited
fragmentation, in brittle materials to the crusher.
3. Broken materials in the face of crushing load as bear on the two points
(or fulcrum) beam, a pack materials flexor surface itself broken.
4. Stripping two broken face grinding materials made in the relative movement
of materials imposed shear stress, so that material rupture occurred. Of this
fine-grained materials suitable for grinding.
5. Crushing impact of the use of it is broken ore. Impact of the moment is
the role of the ore. For example, the counter-crushing machine is broken in the
main impact.
Chinas stocks fell, driving the benchmark index lower for the sixth time in
seven days, on concern about a cash crunch after interbank lending rates jumped
and profit growth for industrial companies slowed.
China Construction Bank Corp. and China Minsheng Banking Corp. paced declines
for lenders after one-month interbank borrowing costs surged the most since
June. Anhui Conch Cement Co. and Sany Heavy Industry Co. dropped more than 2
percent, leading losses for industrial companies after a report showed earnings
growth for the first 11 months of the year decelerated.
Tight liquidity and slowing economic growth are key concerns for investors
and that hasnt changed, said Wei Wei, an analyst at West China Securities Co.
in Shanghai. Stocks have room for further declines because we dont see a
reversal of fundamentals.
The Shanghai Composite Index slid 18.97 points, or 0.9 percent, to 2,171.14
as of 10:31 a.m. local time, heading for the lowest level since March 16, 2009.
The CSI 300 Index fell 0.9 percent to 2,313.82. A measure of small and
medium-size companies slid 1.4 percent in Shenzhen. Hong Kongs market is shut
today, while the U.S. was closed yesterday for the Christmas holiday.
The Shanghai Composite has fallen 7 percent in December as concern about an
economic slowdown overshadowed the first cut in reserve requirement ratios in
three years on Nov. 30. The measure trades at a record low of 10.4 times
estimated earnings, according to data compiled by Bloomberg dating back to 2006.
For the year, the measure is down 23 percent after the central bank raised
interest rates three times to cool inflation and exports to Europe slowed
because of the regions debt crisis.
Shibor Rate
Construction Bank, the countrys second-largest bank, fell 1.1 percent to
4.49 yuan. Minsheng Banking, the first privately owned bank, lost 0.9 percent to
5.84 yuan. Huaxia Bank Co., partly owned by Deutsche Bank AG, slid 0.7 percent
to 11.10 yuan.
The Shanghai interbank offered rate, a gauge of the cash banks have on hand
to lend to each other, has surged 101 basis points this month to 5.81 percent.
It touched a two-month high of 5.89 percent on Dec. 22.
The jump in one-month interbank borrowing costs is adding to speculation
Chinas central bank will cut reserve requirements to support economic
growth.
Its possible the PBOC will cut the reserve ratio again before the Chinese
New Year, a week-long holiday that starts Jan. 23, said Lily Wei, a
fixed-income manager in Beijing at Harvest Fund Management Ltd., who manages
about 11 billion yuan ($1.7 billion). Demand for loans usually shoots up at the
beginning of the year. Given GDP and other indicators signal slowing, if the
PBOC really wants to boost growth, itll lower the reserve ratio.
Slowing Industrial Profit
Anhui Conch, Chinas biggest cement maker, dropped 2.8 percent to 15.05 yuan.
Sany Heavy, the largest machinery maker, slipped 2.1 percent to 11.92 yuan.
China First Heavy Industries Co., a maker of equipment used in the mining and
energy industries, fell 2.5 percent to 3.10 yuan.
Net income for Chinese industrial companies increased 24.4 percent in the
first 11 months of 2011 from a year earlier to 4.66 trillion yuan ($737
billion), the National Bureau of Statistics said on its website today. The pace
compared with 25.3 percent gain in the first 10 months and a 27 percent rise in
the first three quarters.
China will set a growth target of about 11 percent for industrial output in
2012, the same goal as was set for this year, the Ministry of Industry and
Information Technology said on its website yesterday. Industrial production will
probably grow 13.9 percent this year, China National Radio reported separately
yesterday, citing comments by Minister Miao Wei at a conference.
Of course, China's stocks had also made some effects on Mining Machinery
Industry. In new year, China government will take effective measures to control
these situations.

It must be secured to find the best Nest for mining but how
Mining accommodation is among the things that must be secured, if you are
running a mining business or activity. Mining is a process that extracts natural
minerals from the depth of the earth. Most often, the mining is located on areas
that are outside the city. It can be in caves, hills, mountains, or plains.
Sometimes, it can be just within the city.
Regardless of the location, there should be a place or shelter where miners
can take their rest and sleep. If you are involved in mining activities, it is
part of your duty to stay in the area. You can only leave there once or twice a
month depending on the stipulations of the contract. The accommodation must of
course provide comfort and safety to miners. As it is impractical to build
houses or structures for shelter, these associations or organizers resort to
making use of existing resources. One of them is the shipping container.
Shipping containers are made of steel, hence, they can last for almost a
lifetime.
The primary purpose of containers is storage, so you can guarantee that the
merchandise is safe while kept inside the container. However, since it is steel,
the temperature inside it is also high especially during summer.
Shipping containers can be renovated to become a comfortable shelter. Among
other things, they are used to construct apartment, studio, condominium,
offices, classrooms, and even clinics. For mining accommodation, the shipping
containers are perfect. Engineers or construction workers would use several
containers to make several shelter rooms with kitchen and toilet.
Shipping containers are cheaper compared to the raw materials in building a
structure. Also, since mining activities are not forever, it is only practical
to use containers because at anytime, the mining activities will stop, and the
purpose of the shelter becomes useless. The containers come in different prices,
depending on the age of the containers.
They are also resilient. They can withstand the extreme weather conditions of
an area. So, if the mining locations are either prone to winter or summer
months, the containers are durable.
In order to make summer bearable, air conditioning systems can be installed
or a portion of the containers are cut to give way to windows. Some
professionals cover the entire containers with another with Styrofoam or carton
materials coated with Uv protectors.
Another advantage of containers is accessibility. After a few years of using
them, shipping lines are not hesitant to dispose the containers. Hence, they are
easily available wherever you are. Despite the locations, these steel container
vans can be transported and delivered. Whenever there are docks, containers are
sure to be available.
Constructing a building or structure require cutting of trees. But, if you
choose container vans as a pre-existing structure, you are helping save the
environment. Hundreds of trees will be saved. Dumping them in landfills will
take thousands of years before they are completely disposed of. Even then, the
chemicals and rust are harmful to the environment. Using them such as for mining
accommodation is a brilliant idea.
There are several forms of mining that are used to extract minerals and rocks
from layers of earth and open-pit mining is one of these methods. This method
uses a borrow or open pit and is most frequently used in situations where the
desired rocks or minerals are located close to the earths surface.
A. The Structure of the Open-Pit Mine
An open-pit mine is structured in steps, often also termed benches, which
are the pits vertical levels. These steps commonly range from four to sixty
meters, but the size is largely dependent upon the machinery used by the mining
company. The walls of the pit are called the batter, while the flat portion is
called the berm or the bench.
Open-pit walls will generally be dug in a manner that minimizes any danger of
rock falls or landslides in the event of poor weather conditions such as heavy
rain. However, there may also be supports such as rock bolts or shotcrete used
to stabilize the area for workers. In addition, many open-pit mines require
water relief measures to be put in place. In some instances, bore holes may be
drilled into the wall, which can also cause wall failures.
B. Hauling Rocks and Minerals from an Open-Pit Mine
All mines have to have a way to haul out the ore that is mined. Most open-pit
mines have a roadbuilt at the pits side specifically for hauling away the ore,
as well as any waste rock. This roadallows trucks to move safely beside the
mining area and obtain their respective loads.
The waste is also an issue that has to be dealt with accordingly in any
mining situation. In mostcases, waste rock will be placed in a waste dump, often
an area close to the pits edge that is alsostepped in structure.
C. What is Left Behind by Open-Pit Mines?
Tailings are a telltale sign of a former mining operation. Tailings are the
leftovers of ore that was processed and, if fresh, it is often found in slurry
form in a settling pond or what is called a tailings dam. The water eventually
evaporates and, if left unattended, may pose a hazard to wildlife and humans
alike. Tailings may have high levels of toxicity because there are often sulfide
minerals present in them, along with cyanide and other chemicals used in the
extraction of ores and minerals.
D. The Commonality of Open Pit Mines and Their Fate
Most people refer to open-pit mines as quarries, so they are a great deal
more common than onemight otherwise realize. In most areas that they exist, open
pit mines are often repeatedlyenlarged to the point that the resource has been
exhausted or until the mining process is nolonger economically feasible.
Once an open-pit mine is closed, there are several scenarios that may occur.
Reclamation andrestoration has been a more recent issue, meaning that some
companies that own open-pit minesmust take measures to restore the land prior to
leaving the site. Other areas convert these miningareas into landfills, lakes or
other ventures.
World countries will give priority to the development of coal open mining as
the main way to increase coal production, as long as the conditions and try to
achieve centralized mining, to raise productivity and reduce costs. Opencast
coal mine are generally buried in the ground the environment is harsh, broken
line basis generally do not create, and use their own mobile crushing station drive
in any terrain conditions, can achieve the development of workplace. Mounted mobile crusher crusher
(rough crushing with jaw
crusher, impact crusher
with the broken, with crushing cone
crusher, stone crushing and shaping needs optional sand making machine),
screening system, monitoring system is one that enter the job site without
having to install the work immediately.
The introduction of mobile crusher station, confirmed that the current show
broken machinery of digital product development, parallel, integrated and
knowledge-based trend. One figure has become the core of rapid technological
innovation and development. Advances in information technology, and promote no
one from the current mining technology, mining technology to automate the
traditional core of the automatic or remote control mining mining to advanced
sensors and inspection and monitoring system, intelligent mining equipment,
high-speed digital communications network, the new mining process integrated
into the main technical features such as 'no man's crusher' development, mobile
crushing plant into China's coal mining area.
Construction waste recycling rate is high, the use of a renewable resource.
Construction waste in the waste by sorting, crushing, most can be re-used as
renewable resources, such as brick, stone, concrete and other materials through
the broken, can replace the sand for mortar, plaster, play concrete pads;
focused on the latter to recover scrap metal smelting, metal materials can be
re-made; bamboo wood waste can be used in the manufacture of artificial wood.
Utilization of construction waste is to save resources and protect the
ecological and effective way. So in recent years, especially in construction,
building materials production, environmental protection and related industry has
begun construction waste recycling, resulting in a certain economic and social
benefits. Production of building materials using construction waste, but also
reusable building materials, renewable, recyclable find a way out. Current use,
though not very common, but its market prospect is broad.
Catering to this trend, Henan Hongxing manufactures mobile jaw crusher, mobile impact crusher,
mobile crushing station and other advanced crushers to meet clients' demands and
markets' needs.
Prediction and evidence of stable growth rate for mining crushing market
Data indicated that during the second five, China mining machinery (crushers,
sand making machine,
industrial milling machine), construction machinery will continue to be steady
growth rate of 17% growth for three reasons.
First, China's urbanization rate is 47%, which compared with 80% of
urbanization in developed countries there is still much room for growth, and the
country is also increasing urbanization in the implementation efforts, enough to
support this part of our mining stone machinery, construction sand making
machinery, construction machinery industry increased steadily.
Second, the emerging industry to become the strategic focus of China's
economic development, so future high-capacity long-equipment manufacturing
prospects are very bright.
Third, although China's tightening monetary policy, fiscal policy is still
active, the future growth rate of fixed asset investment is still able to
maintain 20% growth, such a growth rate of investment in fixed assets is
calculated, the second five at the end China mining machinery, engineering
machinery sales will reach 900 billion is not a problem.
China mining machinery, engineering machinery industry's rapid development
over the past 10 years, thanks to national policy, but during the second five,
the country's policy to enter a period of adjustment. In high-speed development,
the industry actually needs some adjustment to future growth of open space,
mining machinery, engineering machinery industry should seize the opportunity of
adjustment during the second five, and strive to organizational innovation,
innovation, and increase overseas M & A to make the future to more healthy
and sustainable development.
China has become the world's construction machinery, mining machinery is the
largest market, China's right to speak is very small, because China's
construction machinery, mining machinery industry compared with foreign
countries, there are technical standards, safety standards are not uniform and
many other the bottleneck, while China's construction machinery, mining
machinery industry to keep learning, to get rid of the kinds of impact the core
components.
China and developed countries, there are still a large gap between China's
mining machinery, engineering machinery future direction of the high-end
equipment, intelligence and equipment. China in the future if they can be
resolved within five to ten years of independent research and development of
high-end components, then the voice in the world will be able to upgrade.
China's manufacturing industry to achieve the future of information technology,
technology to transform traditional manufacturing industries. If you want to
break up the core components, we must strive to achieve self-development or
acquisitions abroad.
Continuous battle for junior and small mining company
China is hungry for metals, whether were talking copper, iron or aluminum.
So is Europe and, in fact, the rest of the industrialized world. We are seeing
an insatiable building up for mining companies, whether early-stage or in
production. The interest is in mining the metals in the ground.
The market action points to speculative buying of mining companies,
especially those with a massive reserve of metals in the ground waiting to be
developed.
Just take a look at the proposal by Cliffs Natural Resources Inc. (NYSE/CLF)
to bid for Canada-based mining company Consolidated Thompson Iron Mines Limited
for CAD$4.07 billion. At stake is the massive concentration of iron ore in the
ground, which is used to make steel.
Another ongoing battle in the Canadian mining sector has dragged on for
several months to acquire the massive but undeveloped iron-ore deposit located
on the Mary River project in the Canadian territory of Nunavut, which is held by
Canada-based Baffinland Iron Mines Corporation (TSX/BIM).
The battle for Baffinland Iron Mines began in September 2010 when Nunavut
Iron Ore launched an initial bid of CAD$0.80 for the company. It is interesting
that Nunavut Iron Ore was formed for the sole purpose of buying Baffinland Iron
Mines and is backed by private U.S. equity.
The problem was that the CAD$0.80 bid was vastly under-valuating the value of
the iron ore in the ground. Yes, it will cost an estimated $4.0 billion to get
it out; but once this is done, analysts believe that there will be enough iron
to feed Europe for years.
This is why the battle is ongoing for this junior mining company that has
incredible potential. The bids have steadily risen after Europe-based steel
behemoth ArcelorMittal entered into the bid. The price of Baffinland Iron Mines
traded as high as CAD$1.58 on Wednesday, nearly double the initial bid price.
And, by all estimates, the price required will continue to rise. ArcelorMittal
has a battle chest of money available for higher bids. Nunavut Iron Ore has
limited finances, but has said that it is seeking out cash-rich Chinese
companies that are also hungry for iron resources to fuel the countrys massive
economic engine.
Arbitragers have been trading the stock based on expected higher bids, and so
far this has played out well. If you see bids like this surface and especially
on smaller mining companies, then you can try to make money buying in and
selling higher. Or scope out small mining companies with vast resources. These
companies will drive speculative trading in 2011 , 2012 and beyond.
