A lot of energy is expended to accomplish this, and

States, more coal is strip mined. Water use in coal mining varies according to the method of mining, the equipment used, and the availability of water. Underground coal mines in West ia rely on the use of water for cooling the cutting surfaces of mining ma­ chinery and for inhibiting friction-induced ig­ nition of coal fines or gas.

A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.

By Cai Chen, senior price reporter for Fastmarkets AgriCensus Tens of soybean crushing plants have been ordered to shut down in China, particularly in Jiangsu and Tianjin, as provincial governments have curbed electricity supplies to the sector in a bid to meet stringent emission targets, several industry sources told Fastmarkets AgriCensus Thursday September 23.
