The Sand making machine is widely used for crushing hard and brickle materials including various minerals, abrasive material, refractory material, cement, quartz, iron ore, etc. Sand maker is especially suitable for making sand for buildings, road building. The HX Sand making machine (sand maker) consists of inlet, material-scattering device, whorl crushing chamber, impeller, main shaft, base, transmission drive, motor, etc.

Working principle of sand making machine

Working process: Materials fall from the upper part of the machine to impeller which rotates at a high speed. Under great centrifugal force, they hit materials scattered around the impeller. After hitting each other at a high speed, there forms a vortex between impeller and shell. Materials hit and abrase each other for several times, finally smaller pieces come out through downside outlet, then go to vibrating screen which controls the size of final product.

Materials are transferred to sand making machinery from hopper, then they fall into two parts by material-scattering device. One part falls to the impeller which rotates at a high speed from material-scattering device. In the impeller, materials rotate at even higher speed, and their acceleration is as big as hundreds of acceleration of gravity, then they are thrown out through three passages of impeller at a speed of 60-70 meters/second. They firstly hit part of materials falling from material-scattering device, then strike with materials inside the cavity, and rebounded by underlayer to top of cavity, thus its direction of motion changes to downward, then materials fall from the impeller passage form a continuous fall. Then one piece of stone will be hit, abrased for twice or more times in the crushing cavity. The closed circuit forms, usually materials can be crushed to smaller than 20 mesh after three times in the circulation. The crushed materials will be discharged from outlet. They hit each other but will not hit metal parts of equipment directly because of material underlayer, thus the pollution is less, and service lifetime of equipment is prolonged. The cute air current self circulation in the cavity removes the powder pollution.

With the technology development, marketing ways are more and more. Especially, online business and company owners continuously search for different marketing strategies to help increase their income.

For mining machinery such as impact crusher, mobile crusher, energy-saving cone ball mill, and most of them already tried Internet marketing, Email marketing and more but they are still not contented on the results. These marketing strategies are effective but a lot of business owners are already using them. It means that you have a lot of competition on this kind of marketing strategy. This is the main reason why they are looking for other ways to increase their income.

This is where Text Message Marketing comes in. Some people think that it is just the same as email marketing. It is different and it is better than email marketing. There are a couple of reasons why this kind of marketing strategy is the best choice today.

First, you can enter the personal space of the potential clients. Mobile phones are personal items by a user. It means that no matter where they go, they always have their phones with them. They read every text message that they receive and it is not like email messages. People already had enough of virus messages on their email so they tend to ignore messages that what they think is just a spam.

Second, you can target a more specific group of people. Basically, you will not force someone to give their numbers to you. It is just like how internet marketers obtain emails for their list. You can ask the users to input their mobile numbers on your website. The best thing about this is that only the users who are interested on your products and services will probably sign up their mobile numbers.

Third, a lot of people are using mobile phones. Actually, it is said that the number of people with mobile phones are higher compared to the people with laptops or desktop computers. Also, some people prefer using their phones in accessing the Internet. However, you need to make adjustments on your website and try to make some advertisements that will appear on mobile phones. This is also the place where people can place their mobile numbers.

Fourth, you can have direct contact with your customers through Marketing Service. You can talk directly to your customer if they inquire about your products or services. Instead of providing information through emails, you can call them directly to provide information.

The design of the sand stone crushing technological process should use the dry production process which relatively have little influence on the environment at the premise of meeting the concrete aggregate technical requirements. Using wet production process must take reasonable wastewater treatment process for the comprehensive utilization of waste water, waste residue, waste to treasure, and minimize the waste disposal to meet demands of environmental protection.

In the process of mining, processing, it is easy to bring damage and harm to the environment and human life environmental, which include the damage on vegetation and slope body stability caused by material mining, the dust and noise generating in the process of crushing and screening, which have very seriously impact on the air quality and human survival environment. What's more, the waste water and waste residue generating in washing the screening machine enter the river valley, land, which will impact the environment a lot.

Especially, in the crushing and screening process of the aggregate, in order to ensure the quality of finished aggregate and reduce the processing cost, generally according to the processing characteristics of raw materials and the different scale, processing technology include two kinds of craft union: full dry production and full wet production. It will generate large amounts of dust and noise in the sand stone materials' crushing process, screening machine driven by the motor vibration exciter to make the material on the screen surface for a straight line or circular motion, the mechanical movement of the material and the screening machine will produce noise as well. Dry screening will produce a large number of dust, while as with the wet screening, a large number of sewage need to deal with.

Sand and gravel processing equipments are mostly strong noise and dust source, when pollute the surrounding environment which will threat the staff's health. So we should consider in advance when selecting the equipment and technical design.

Current wave of globalization has been driven by not only investment but also information technology and international trade. Investment and development in overseas has became a hot potato nowadays. But for mining industrial, whether or not it is a good thing still need to be tested.

Chinese mining companies will continue to increase both purchases and investment in the overseas market in 2012, the experts revealed. But China's mining industry was strongly influenced by the continuously increasing acquisition activity overseas. But expert pointed out it is right to keep quiet in the first half year against the soaring price of high level resources. Because the good time for M&A activity now is coming, and there will be a slight rebound in the price after the huge declines recently.

Expert predicted that Australia and Canada will continue to be the main target markets for overseas investment, but said that Chinese mining companies will continue to invest in and explore more mines in other countries such as those on the African continent.

But unfortunately, possible resource and carbon taxes, proposed by the Australian government , are likely to come into effect in July next year, which will undoubtedly impose pressure on Chinese mining companies.

While,Canada is expected to see an increase in investment from Chinese companies in the mining industry, the country warmly welcomes Chinese investors in the mining industry. Meanwhile, some other Industry insiders also pointed out that even though China has signed many M&A contracts with foreign companies, not all of the deals will be completed because of alleged problems with the managements.

It seems like management is a big risk for Chinese companies and Chinese companies should build better relationships with foreign companies to ensure cooperation in the exploration of resources. It may better for Chinese companies to look further attracting necessary funds over the long term. And they also need to build the necessary relationships to gain access to foreign markets.

Coal mill also called coal pulverzier or coal powder mill is grinding mill that is used in coal mining industry, such as vertical coal mill. And in general, vertical mill includes mineral series and coal series. The first series grinder can be widely used in cement making, power, metallurgy, chemical, ore industries. And the vertical coal mill also called coal grinder is the most used machine for coal grinding according to our mining experience. In some cases, coal mill is not just one grinder mill, it will include some optional equipment such as vibrating feeder, vibrating screen, belt conveyors and so on to finish the coal milling process. So, coal mill is also used widely in many industries besides coal mining.

Coal mill is an efficient tool for grinding coals into fine powder in coal mining industry. According to its fineness and working principles, we divide coal mill into coarse power coal mill and fine coal mill. Coarse powder mill is a kind of new high-tech milling machine to meet the requirements of coarse powder processing customers. It is the ideal equipment to replace Raymond mill, ball mill, and other traditional mill which only process fine coal powder materials.

Ball grinding mill is the early coal mill used in coal powder plant, there are two types: wet ball mill and dry ball mill. Vertical mill is the most common coal grinding mill in milling plant, so vertical mill is also called vertical coal mill, it set up the coal mill standard. Raymond mill is also the early coal mill; the capacity of this coal mill can be up to 6-8 t/h. The fines of the finished product can be adjusted from 100 meshes to 325 meshes according to the requirements.

In coal fired power plant, coal mill is used to grind, pulverize and dry coal before the coal is transmitted the boiler. The coal is feed into the coal mill via a inlet pipe so that the roller coal mill such as Raymond mill and vertical mill can pulverize the coal into particles.

The hot air in the coal mill will lift the coal particles out of the Raymond mill or vertical mill and into the boiler, if the coal particles are too heavy they will drop to the bottom of the coal mill too and will be grind, pulverize again.

The coal flow into the boiler is an important factor for a coal fired power plant. But in fact, it is not easy to measure the coal flow from the coal mill to the furnace. The coal flow out of the coal mill is often estimated based on the incoming coal flow.

We are the professional manufacturer for coal mill machines, and our best coal mill types,coal mill design is possible suitable for you!

If you are new in stone crushing industry, you might find it difficult to design a stone crushing line and you want to make it clear when your technician recommend you a scheme. Then, how to get it easier for understanding?

First, don’t think you are crushing stones, just impagine that you are making salad. You have got many vegetables and fruit with different size and different hardness.

Then, think about the first step of crushing. To crush tofu, you can use your hand, knife or something to get it into pieces. Thus, to crush soft material like tofu, you just have to use kefid jaw crusher or impact crusher, which will not be worn a lot in short time. If it’s meat, knife is the only choice, you can’t cut them into pieces with your hand. So, if material is hard, you can only use jaw crusher or cone crusher.

Thirdly, consider how to get material with smaller size. If you want to have salad, some block-shaped or piece-shaped material will be necessary and you might need crumb with quite small size. So, if you need small size material, say below 5mm, vertical shaft impact crusher will be necessary.

Fourthly, why we need crushing in different steps. That’s just like you want to crush bananas into banana juice, you have to crush it into pieces, so that they are ok for the feed opening of the fruit juicer. So, you need jaw crusher for primary crushing; impact crusher, cone crusher and secondary jaw crusher for secondary crushing; and VSI for tertiary crushing.

Hope I am making a clear interpretation, for further information, you can visit we Henan Hongxing Mining Machinery Co., Ltd. website where you will obtain more knowledge and further knowledge about mining machinery industry.

One complete set of stone production line should include: vibrating feeder, primary crushing equipments, secondary crushing equipments,vibrating screen, conveyor belt, and electric control panel and so on. Our company can provide many kinds of schemes for customer’s choice. These plans are optimized combination of equipments’ features and customers’ demand.

1). Vibrating feeder + jaw crusher + Multi-cylinder Hydraulic Cone crusher+ reshaping machine (VSI sand making machine) + vibraing screen

Main charaicteristic of this plan is that it adopts advanced multi-cylinder hydraulic cone crusher. This makes fine products take a bigger proportion. 80% of the finals can be smaller than the size of discharge opening. It will obviously increase processing capacity and decrease general energy cost. Add reshaping equipment to the secondary crusher can assure the quality and shape of the final products on one hand; on the other, some sands can be chose for other usage.

The efficiency of the whole line is very high. Working life of easy-worn parts is long. Continuous operating time of the equipment is longer, and it is easy maintenance. Its general economic profits are higher than the traditional plan.

2). Vibrating feeder + jaw crusher + CS cone crusher + reshaping machine (VSI sand making machine) + vibraing screen

Impact Jaw crusher and cone crusher, the final products manufactured by impact crusher obviously have a higher quality with excellence, stress-free and cubical-shape. What is best? They are very uniform.

Usually, the bearings’ temperature should be below 35 degrees. When it is over 70 degrees, the machine must stop operating to have an amendment in details. If the bearings of impact crusher always keep working on a high temperature, it will be damaged greatly, which even make the rotor’s main shaft in a dangerous situation.

According to experiences from our engineers, the reasons and solutions are as follows.

1): the bearings need lubrication. You just add lubrication oil on it.

2): the lubrication oil is polluted and loses the function. You just replace them.

3): the up cover of bearing is too tight. Loosen it.

4): the bearings are damaged. Replace them.

In addition, different machines from different companies will be different qualities. Maybe the structure of machine has some troubles when it left from factory. For example, the rotor ( the core part of impact crusher) hasn’t passed the test of balance but installed. With this reason, you should ask some maintenance from manufacturer where you bought the machine.

Hongxing Group is leading Chinese manufacturer & exporter on mining equipments. We are very professional on PF Impact crusher, and European Impact Crusher. Anything details, in our company website you will find all informations that you need.

For 2011, China engineering machinery industry had the memorable development, and the market gone ups and downs. With the European economic crisis and the block of rail way construction, China engineering machinery industry requires flying development in the Year of Dragon.

Investment: Real estate, Highway construction develop slowly

For engineering industry, real estate is important in the past 5 years and its investment took up 23% of fixed assets. Through the policy control for 2 years, recent real estate stands in important milestone. According to the experiences, the sharply shriking of sales volume must make the investment speed slow in a large degree.

In highway construction, the attention is a little weak. The main test is in the aspect of the financial strength of financing platform and financing capability. Although the tone of 2012 is still for active fiscal policy, but the highway construction still faces the awkward situation of no investment.

Anticipation: Potential investment on Highway, Mine quarry and Water conservancy

According to information, the two most important pressure existing in railway construction is Capital and Security. Security decides that the investment will not be as large as input in the first three years to the whole '1025' period and the engineering equipment pulls function abate. Recently, with the biggest problem of Cpital, in the high debt, a lot of the shutdown in short time of the project is unlikely to return to work with the high debt and influence financing channel.

Under the high prices in resources and steadily rising demands, the fixed assets of mine quarry have continuous growth. In 2012, in the environment of global economic slowdown, the resource prices are expected to fall, but the posibility is small. And the expectations of domestic mining investment remain steady growth.

Form 'a date file' of 2011 which locks water conservancy construction, the whole society pays great attention to water conservancy construction. In the first 11 months of 2011, the fixed assets investment in water management is higher than railway and highway construction. As we all know, 'a date file' in every year is related with the problems that are the social focus and need solved urgently. Therefore, the local government in water conservancy construction will have larger impulse.

Hello, every one. I am the important part in mining machinery industry. And my name is Impact crusher. Do you know me well? OK, here you will be familiar with me after a short time.

Impact crusher in impact in the process of material has the ability to make its selective fragmentized than other types of crusher has more set square broken product content, but also has a broken than big characteristics, simplify crushing process, so the broken industry obtained a rapid development and is widely used in the relevant industries.

The so-called impact crushing is to point to in the free state object hit by force, and its natural fracture, the bedding face, joint surface and so on parts of the weak and selective fragmentized broken. It is different from the hammer the broken in a binding objects in the state hit by force, with other shear, more economic pressure, different grinding broken, and in the process of the lowest energy consumption in broken, and due to its selective fragmentized separation has the ability of monomer and obtain more valuable mineral products made the role of the square.

Application of the principle of impact impact crusher, is using high-speed turn head to people to hammer crushing cavity raw material the high-speed impact, make the material impact crushing, and that happened after the impact of the material by high speed to counterattack board, and the material is in again after impact crushing, and from counterattack board bouncing hammer blow repeated the fracture process area, and the material in the hammer and fight back and forth between the board, still exist between each other collision impact. When broken material particle size of less than hammer and counterattack plate gap between when the machine is in discharge from for breaking up products.

As mentioned above, the impact crusher in be used actually exist the material not even, and easy to 'run large', impact hammer crusher can make be these solved the problem.

From incoming material mouth hello man-machine inside, into the hammer in the working area, high speed rotary hammer by the impact and broken, but, material and in high impact in a counter board is further broken, and from the board to hammer bouncing back work area, continue to repeat the fracture process, and finally into the hammer the area (hammer and the working area between article labyrinth), in article labyrinth further by the hammer hammer blow and abrasive. Practice has proved, and the material is not in a cycle of rotor fully broken, but after many cycle to get fully broken. Large materials may be in shock process has not been fully broken. Can be through the back plate and hammer between disk roller function get broken, the effect has been practical experiments (with no labyrinth of article, its greatest product size not more than hammer dish and counterattack plate gap size).

As one of the mining machinery, we grinding mill family are important for this industry. If you don't know us clearly, you can't operate fluently and get high benefits from the production.

This grinder is a new type in recent years. Its birth breaks the limitation that traditional grinders can't produce in large scale. In this way it not only improves the unit output of a single equipment, but also fills in blanks of domestic large grinder market.

1, the machine except spindle top sliding bearing outside, the rest in rolling bearing transmission part, and therefore must be in good lubrication condition, can damage otherwise bearing, shorten service life. Maintain the method is as follows: spindle come on time every time, but must pay attention, oil cup of oil found in no loss or loss too slow, immediately wash oil way, oil cup in spindle position at the top, the spindle bearing, grinding roller bearing base a class of each gun in the butter filling # 3 lithium and manufactured a parser bearing every six months apart cleaning time, add the lithium # 3 and manufactured, the fan bearing room and lithium base grease.

2, it is strictly prohibited to metal piece into the machines, or you will damage the grinding and grinding ring, even central hanger, etc.

3, charging should even, not less, and more. Charging too much will more duct, reduce production, easy to burn out motor, charging too little will feed production. Feeding particle size: hard materials in diameter less than 15 millimeter advisable, soft materials for 20 mm in diameter, forbidden large materials to join in the machine.

4, air volume adjustment: located in the intake pipe air volume control valves on the fan, in general, the largest open position, according to the fineness and production requirements appropriate adjustments. Located in the export of exhaust gas regulator, transferred to feeding mouth place no dust jet can. Air volume small, thin degree is high. But they should pay attention to, air volume small, the host of the precipitation in the wind beneath easily material, please adjust.

5, fine degrees adjustment, according to the size of the material, soft hard, moisture content, different proportion, processing degree of different degrees, which can adjust the above parser, high speed, high fineness, speed is low, the fineness low. Improve the fineness, the output will be reduced, if also can not reach the requirements should debug fan speed, the user can be flexible.

6, grinding roller grinding ring the abandonment of limit, the remaining minimum thickness is not less than 10 mm.

7, parking, first stop feeding, host still continue to expect them, make of the remainder of the abrasive continue to ground, about a minute later, can close host motor and motor analyzer, stop grinding work, followed stop fan motor, so that blowing off of the remainder of the powder.1, the machine except spindle top sliding bearing outside, the rest in rolling bearing transmission part, and therefore must be in good lubrication condition, can damage otherwise bearing, shorten service life. Maintain the method is as follows: spindle come on time every time, but must pay attention, oil cup of oil found in no loss or loss too slow, immediately wash oil way, again add 50 # JiXieYou, oil cup in spindle position at the top, the spindle bearing, grinding roller bearing base a class of each gun in the butter filling # 3 lithium and manufactured a parser bearing every six months apart cleaning time, add the lithium # 3 and manufactured, the fan bearing room and lithium base grease.

Then, this class is over. How much do you learn?

Ball mill, as a common grinding equipment, was widely used in beneficiation, construction materials and chemical industries. In terms of grinding way, ball mill can be divided into two types：wet type and dry type. And in terms of discharge mode, ball mill can be divided into overflow -type and lattice-type.

Generally speaking, there are three direct ways to improve productivity. before using ball mill, use a crusher first. Improve the design of ball mill, so the grinding efficiency can be improved.use a efficient classifier in the production line .As we all know, ball mill is an important equipment used to grinding materials after primary crushing.Ball mill is widely used in cement, silicate product , new building materials , refractory materials , fertilizer, black and non-ferrous mineral and glass ceramics and production industries, and all kinds of ores and grind-able materials can be grinded through dry or wet grinding ways.The above three methods , any one can greatly improve mill yield . Of course, if conditions permit, supporting the use of the above three methods , the effect is the most ideal.This is the design trend of grinding system domestically and internationally in recent years.

Crushing the materials before grinding by mill makes the particle size greatly reduced , thereby reducing the grinding system load ; the most direct benefit of the improvement of separator efficiency is that fine finished product be discharged in time, so the the rate of finished product back to the cement powder was greatly reduced and reduce the load of ball mill; the particle size into the mill was reduced, separator efficiency was improved, so both the productivity and materials quality can be improved.Our ball mill plants are used to process limestone , basalt, chrome , dolomite, feldspar, fluorite, kaolin ore, marble , granite , iron ore ,copper ore , sandstone, silica , gold ore , silver ore , lead ore ,with capacity 1000 to 5000 tph,we’ll give our customers adjust advice for the mining solution.Our engineer will accompany you to research you mining and construction industry to be solved.

Finely made into the ground before grinding material particle size reduced greatly, which reduces the grinding system load; Choose to enhance the efficiency of powder, the most direct benefit is finished product fine powder is maximum elected in time, reduce the cement products back to powder rate, reduce the mill load; And grinding of reform, is also the grinding system improvement, is the most fundamental solution. Into the ground material particle size reduced, select the powder efficiency raised, if griding system efficiency is low, the impact is not only the mill production, more affecting quality.

Recent years, our advanced industrial information technology for the control and optimization of integrated systems, electrical power grids, buildings and industrial processes saves energy and reduces emissions. The interconnection of power systems with high-voltage direct current technology makes large savings through a more even distribution of loads and a more efficient use of primary energy resources, thereby reducing CO2 emissions. It also enables large-scale integration of renewable energy into the power grids.

Saving energy can help cut your household costs and benefit the environment. A significant portion of energy expenditure in the home goes into running appliances. Making sure appliances run efficiently can reduce waste and make for a more environmentally friendly home. There are opportunities for saving energy in appliances throughout the home.

Environmental protection is a practice of protecting the environment, on individual, organizational or governmental levels, for the benefit of the natural environment and (or) humans. Due to the pressures of population and technology, the biophysical environment is being degraded, sometimes permanently. This has been recognized, and governments have begun placing restraints on activities that caused environmental degradation. Since the 1960s, activism by the environmental movement has created awareness of the various environmental issues. There is not a full agreement on the extent of the environmental impact of human activity, and protection measures are occasionally criticized.

Hoisting equipment is oriented on the safety and reliable work, which adopts the computer control and dynamic measurement technique on the working life and efficiency and the build-in attrition elevator on the machine structure. The crushing equipment adopts hammer double-rotor impact crusher and the product structure is developing for the fine crushing. The development of high-new equipment requires plentiful functional materials and the application of modern fine crushing technology has become an important symbol of embodying the national technology level.

Many of the earth’s resources are especially vulnerable because they are influenced by human impacts across many countries. As a result of this, many attempts are made by countries to develop agreements that are signed by multiple governments to prevent dam age or manage the impacts of human activity on natural resources.

With mechanized mining of coal resources, coal is pulverized and the share of the end of the column increases. With the chase and in the coal washing plant to produce slime and coking coal washing practice increased coal flotation tail. Both as more and more slime out of coal by-products. As the slime has a fine grain size, water holding strong, high ash content and contain more clay, etc., for the utilization of slurry inconvenience, most of the washing plant sludge is sold to local farmers.

Coal slime drying machine, also called coal slime dryer, coal dewatering machine, coal slurry dryer, coal mud dryer, coal sludge dryer and so on. It is a kind of highly efficient, stable and reliable heating drying equipment, designed to dry materials of high moisture or strong stickiness. It’s performance are better than tube bundle rotary dryer, blade rotary dryer. Its features are big capacity, low energy cost, and high efficiency. It’s applied in the materials like coal slurry, mud, filted gypsum, Muddy, high-moisture swell soil, electroplate mud and so on.

Large series of slime dryer mainly broken by the drum dryer, furnace, feed screw, a feed screw, pipes, dust, wind off device, fan, control cabinets and other components.

Using four dehydration process: a dry area to the feeding mainly in high humidity conditions, after transient inlet temperature 600 ℃ and the heat transfer and mass transfer slurry to remove most of the water, and difficult to fire; two drying area is ranked bonded area, the indoor temperature is 450 ℃; three drying area is downstream drying, room temperature 300 ℃; four dry zone is a high-drainage areas, the indoor temperature is 100 ℃. The whole process is a low-temperature drying, sludge is not likely to cause burning, which can really play the energy saving effect.

How is the complete drying slime production line? Ore from the feed screw directly into the dryer drum crusher, drum wall is repeated on the copy board took a scattered, scattered through the crushing blow after installation, materials and negative pressure high-temperature media full access to complete heat and mass transfer process. As the drum inclination and lead sub-air role, the material slowly moving from the feed end, after drying the material by a screw discharge, exhaust gas through the precipitator dust, into the atmosphere.
