The cement packing machine is mainly used for packing cement in bags, or other fluit powdery material's bagging work. Except manual sidekick, baggs can't fall off unless the bulking load reach centain amount. The machine can stop immediately when bag happens to fall of suddenly. It can charge load without compressing air, which reduces the packer damadge caused by damaged pneumatic components. Most of the cement packer is divided into fixed and rotary.

The work of running processes

1). Start the operation steps: The circular telegram - starts the belt fastener - start the packer - start the feeding engine - to insert the bag - to fill installs - measurement - fall the bag .

2). Engine off step: Closes the feeding engine - emptying the cement in the packer - switch off the total power source .

Entire operation and routine maintenance

1). Before driving, we should pay attention to the scene environment, eliminating the influence work the obstacle,forbidding other personnel to close to the rotary packer besides inserts the bag .

2). Before driving, we should inspect the electric appliance part earnestly, the velometer knob position in 0, the turn clockwise knob accelerates to need the rotational speed gradually, each minute engine off must by all means make the velometer return to knob 0.

3). Inserts the bag ,the body and the machine must maintain the suitable distances, preventing to bump into and injure.

4). When fills installs, we does not permit the hand to press, the foot kicks the cement bag, in order to avoid influence measuring accuracy.

5). When the operation appears failure ,emergency stopping maintenance , cutting off power supply, , listing alerts or the specialist care.

6). Packer of grounding protection wants safely reliable,and regularly test ground resistance .

Recently, in order to speed up the reconstruction, all sectors now has a higher requirements to the performance of large mechanical equipments used in the construction. Thus, the development of the mining equipment has gradually shifted to develop and research high tech crusher and grinding mill.

As one of the mining machinery manufacturer walking in the forefront of science and technology, Henan Hongxing has its own special insights on the research and development of new products. We think that the quality of the high tech crusher hammer is the key to the development of a crusher.

Take the crusher used in cement industry as an example, the working environment of crusher in cement industry is relatively bad, which need hammer with strong wear resistance. As with the traditional crusher equipment, because the poor quality of the hammer, it needs to be replaced regularly. The key of research and develop high tech crusher is to improve the wear resistance of the hammer and to reduce the cost of the maintenance. When customers choosing a crusher equipment they mainly pay attention to the service life of hammer, stability in use and whether it is easy to break and so on.

Advanced crusher hammer is generally made by hadifield steel of good toughness, high resistance, which can cushion the impact strength and increase the wear resistance. In addition, the design of the hammer structure is also the emphasis. The geometry design of a hammer are closely to the elimination of the impact force, the effect is obvious especially for the hammer of large thickness and size.

Additionally, Henan Hongxing also believe the gap problem is important, the gap mainly refers to the gap between the rotor body and a back plate and the hammer. The size of the gap is related to the blocking material problem, once there exists blocking materials, it would exacerbate the wear of the hammer. So it is necessary to design a good gap size.

As the weakening U.S. economy, China is set over the United States next year as the world's largest manufacturer, which four years earlier than expected. This great leap forward by the United States provides economic consulting firm Global Insight forecast shows. According to forecasts, China will account for 11.783 trillion U.S. dollars next year, manufacturing value added of 17%, while the U.S. will account for 16. U.S. still topped the list last year, accounting for one fifth of the global total. China accounted for 13.2%, occupies the second.

In Made in China Industry all the way and sing, by leaps and bounds, we have noticed that we are inadequate. We are just a big manufacturing country, not a manufacturing power, and many related key we have not mastered the core technology and manufacturing power, we have a lot to be desired. Therefore, to develop the manufacturing sector, we must earnestly practice the 'scientific development', and vigorously the introduction of talent, technology innovation, so that we can really enter the manufacturing power.

The overall Chinese mining market is dominated by coal, of which 90 percent is underground, in contrast with the US coal market, which is mostly surface mining, according to the JPMorgan analyst Ann Duignan in a research note. After recession hit in late 2008, the price of many commodities such as copper, aluminum and iron ore fell as demand from manufacturers dropped off. Mining companies idled production and laid off workers.

But since last year, metals prices have rebounded sharply, prompting producers to reopen mines and start up idled projects. That has put a strain on supplies of equipment, with some producers complaining they cannot get adequate supplies.

In the mining industry, roller crushers are used to crush mines of medium or low hardness, rocks that have low or medium rigidity during mine selection, for cement, chemicals, and industrial production of building materials, among others. However, their use in the mining industry has greatly declined due to their inability to produce large amounts of output. In mining applications, the roll crusher does not match up to cone crushers, when considering the volume of production and maintenance costs. However, roll crushers have the advantage of producing a close distribution of the product size. In cases where the ore is not very abrasive, the maintenance costs are significantly reduced.

Roll crusher work, paying particular attention to the following:

1) to strengthen the work to the removal of iron ore. Non-broken material (solder first class materials) fall into the room on roller crusher damage, resulting in parking accident. Therefore, lithotripsy should be installed before the addition of iron device.

2) viscous material easy to plug the break room, plug in the treatment failure should stop processing, not to poke mine in operation.

3) when dealing with were more of materials with large, easy to pay attention to large deposits of space squeezed out from the broken to prevent injury or equipment damage.

4) roll crusher run a long time, due to the roll surface wear larger size too small will lead to products, then adjust the arrangement to pay attention to mine mouth or on the device for maintenance.

5) to strengthen inspection of the equipment, lubrication equipment, parts of the fuel on time, maintaining good lubrication equipment.

The flourishing business of illegal mining in Alwar is taking place under the patronage of district administration and police department, claims intelligence report of Rajasthan police that TOI has. As per the report sent on October 18, 2010, T Gutie, the then inspector general (intelligence) mentioned that in lieu of allowing illegal mining, the authorities receive monthly payment from mine mafias. The report says that due to proximity to national capital region (NCR) around 1,500 dumpers reach Delhi and Haryana daily without any hurdles.

A 50-member team that went to Kahrani village in Alwar district to stop illegal mining on Sunday was attacked by the illegal miners. More than six policemen were injured, out of which three have been admitted to a hospital. After the Supreme Court's (SC) decision where it came down heavily on state government's inability to restrict illegal mining, authorities have geared up their efforts to shut these mines.

The team was able to close down 27 mines in Tijara and seized 50 stone screening plants along with 8 crushers at Udhanwas in Alwar. 'Following the SC orders we have been taking action against illegal mines and have shut down four dozen units in the past few days,' said JP Jakhar mining engineer. He added, 'With the help of police department we have dismantled the stone crushing units and seized the crushers and other equipment.'

There is full support of officials from police, forest, mines and district administration to provide uninterrupted transportation. The copy was sent to the then home secretary, PK Deb. Despite these intelligence reports no action was taken.

After the strong criticism by the Supreme Court the district collector had issued orders for firm action against illegal mining. 'We are following the orders of SC and all the steps are being taken as per the instructions from the honorable court,' said Ashutosh AT, district collector, Alwar.

Illegal mining is carried out in entire RAJASTHAN and every officer responsible to check it is getting its share .Whether he is from Central Govt or from forest ,revenue ,police and mining.All politicians upto rank of minister are involved.

RWE Power is one of Europe's leading energy utilities and Germany's biggest coal miner. The company would help R-Power design and plan the engineering aspects of captive mine and procurement of equipment and ensure quality control, the company said on Thursday. Government has allocated Kerendari B and C coal blocks of North Karanpura coal fields in Jharkhand to meet the fuel requirements of the Tilaiya project. These mines have reserve of over 1 billion tonne. The company plans to produce 40 million tonnes of coal per year.

'Although a great deal of research has shown that physically-imposing individuals are more likely to acquire power, this work is the first to show that being powerful may actually make people feel taller than they are. We found that people literally perceived themselves as taller when they occupied a more powerful position,' the Telegraph quoted Prof Goncalo as saying.

This is a good arrangement for R-Power to have experienced mining Company to plan, design and mine coal from captive mines from power generation. Arrangement will be helpful for Indian power customers as long as the cost of power produced by this arrangement is going to be reasonable. The cost control and efficiency in producing coal should a key factor regarding success. Indian government and the State need to a watchful eyes in this type of projects. Everyone should win from use of national resources for the good of the people. Government needs update its tax structures along with the ever increasing energy prices up wards. Proper monitoring and tax policy should keep the project winwin for allthe stakeholders.

In the mineral processing industry, production costs cover more than 40% of the total cost on average, while the production costs of grinding covers more than 40% on average. While the investments of grinding equipments account for about 60% of the total investment of mineral processing industry.

All the processes that make large particle materials into small particles through outside force can be called crushing, the mechanical appliance is called crusher. All the processes that make small particle materials powder through outside force can be called crushing or grinding. It can be called powder mill for short. The machinery can be called pulverizer and grinding mill .The machinery that combine the crushing and grinding can be called crushing and grinding machine.

In the cement industry, the role of broken grinding costs in the cement works are around 20% of production costs, and electricity consumption of crushing machinery accounts for about 10% of total electricity consumption, while the powder mill accounts for 60%.

With the economic rapid development of modern society, The demand and production scale of all kinds of metal, nonmetal, chemical minerals, as well as cement, building materials increase gradually, so the material that needs to be crushed and grinded is increasing rapidly. Since the 90s, the annual amount of material through the broken grinding is up to 100 million tons. China's annual output of brittle materials has already reached more than 1.5 billion, of which about 240 million tons are iron ore, more than 100 million tons of nonferrous metals ore, more than 260 million tons of non-metallic minerals, over 30 million tons of chemical minerals, about 400 million tons of cement ,more than 470 million tons of limestone for building. Most of these materials must be broken through the grinding, so we can see crushing and powder projects play a huge role in the national economy.

Many different types of stone crusher, stone crushing production line are often used, complete production line and mineral sand production line stone, stone crushing production. The current breaker Heavy machinery industry has developed into a relatively large branch of industry, the benefits of working the heavy machinery crusher applications for the current situation and the stone industry in a variety of different quality characteristics, according to different Application of sums up the current industry crusher several major categories, including jaw crusher, impact crusher, hammer crusher and a cone crusher and so on.

Jaw crusher is widely used in mining, ore dressing plant, inertial force, poor working conditions, heavy-duty work in primary crushing equipment. In order to ensure continuous operation of the device's normal, full production capacity of equipment, in addition to proper operation, regular maintenance and periodic maintenance, the need for accurate and timely work to determine and eliminate potential failures.

The main operation of the common faults:

A) crusher idling, the lower the metal crash occurred. Jaw crusher working load, the lower the metal crash occurred may be the following three reasons:

1) mobile jaw and fixed jaw broken tooth plate each crash is due to the small port of discharge caused, should be timely adjusted.

2) The thrust plate bearing or gasket conditioning crash occurs, usually disappear by the spring elastic buffer rod or damaged, or does not bear the weight of the spring caused by rotation, when the movable jaw plate, elbow board, the body does not close with the three so that both ends of the support bracket and produced the first shock, or adjust the pads hit each other, should be strong in time compression nut until the crash disappeared.

3) there may be serious bracket bearing wear or loose slider, bracket serious head wear, should be replaced.

B) work with metal crash, backing jitter. This phenomenon is often the crushing chamber side of the liner and the tooth plate (fixed, fixed) loose, loose or broken screws or strong result, it is timely solid or replaced.

C) after the brackets break frequently. In addition to transmit power after the brackets, but also by its lack of intensity from the insurance role. In addition to the middle bracket is too low intensity, the strength enough to overcome the normal force of broken ore crushing damage produced, this may be the weight of the spring rod, together with crushing force when the work overload and break it, may be appropriate to transfer song spring.

D) flywheel turning, crushing machine does not work. Is due to the spring rod and rod damage to the elbow from the trip lever nut bearing slider emerge, it may be broken off bracket, should be re-replacement and installation.

E) flywheel significant swing back to slower eccentric shaft. The fault is due to the pulley and flywheel key loose or damaged, turn the wheel and axle can not be synchronized.

F) broken thicker particle size is Broken liner The lower part of the results of serious wear and tear. Board or under the teeth should be replaced with new liner exchange, port of discharge to adjust the required size.

Whenever adn wherever we must prevent accidents before they occur.
