In the early part of this century efforts to prepare coal were directed to sizing the coal to supply lump coal for domestic use and intermediate sizes for industrial use; the fines were usually rejected as unfit for sale. Coal mines like any other mines and they need sophisticated equipments to run their day to day activities. Inner Mongolia becomes China's largest coal producer. In 2009, Inner Mongolia reported coal output of 637 million tonnes, 22 million tonnes more than Shanxi, China's top coal producing region for 30 years, said a statement from the regional administration of coal mine safety. This year, coal production in northern China autonomous region of Inner Mongolia was set initially at 880 million tonnes, local paper reported.

Coal preparation processes can improve the coal to meet market demands, as limited by the inherent characteristics of a given coal. The top size of the coal can be reduced to any size specified, although control of the varying size increments can be poor, depending on the amount of crushing required. No practical technology is known for increasing the sizes of coal as mined.

Although inherent moisture cannot be changed, the surface moisture can be reduced to any level that is economically practicable. Considerations include the possibility of reexposure to moisture during shipment and subsequent storage and the fact that intense thermal drying increases ideal conditions for readsorption of moisture.

With the increasing coal output, the demands for coal mining equipement are getting more and more, coal crusher, coal washer, coal mill, Raymond mill, coal conveyor... Almost Chinese machinery companies all pay attention to this great challenge and chance to make profits and expand sales market.Henan Hongxing rock cone crusher will be your best choice. Specifically, Inner Mongolia coal consumption in industries of power generation and coal chemical would see a rise of 100 million tonnes each, while steel and building material industries each would have an increase of 50 million tonnes in coal use, relevant institutions predicted.

Mining equipment is what will guarantee the amount of work to be carried out and what result the mining company is expected to have. There are number of manufacturers whose main aim of operations is to manufacture these equipments such as coal mill, coal crusher, coal washer. The Chinese market is known for producing both substandard and standard equipment at low marginal rates and any buyer interested in buying commodities in China must first be conversant with the market and inquire more about the quality of the product he intends to purchase.
