Coal Washing. Coal washing is a process designed to separate the coal particles based on size, density and shape. Achieved by allowing the coal to settle in the wash fluid. Continuous Mining. Continuous Mining is an underground method of extracting coal. The process utilises a machine that is capable of handling the entire extraction process.
Ball mill is the key equipment for crushing materials after crushing.
The ceramic ball mill is a ball mill made of ceramic.
The classifier is widely used in the beneficiation plant and the ball mill to form a closed loop process to split the ore
Magnetic separator is used to re-use powdered granules to remove iron powder and other screening equipment.
Flotation machine is the abbreviation of flotation concentrator, which refers to the mechanical equipment that completes the flotation process.
Shaking table is also known as gravity shaking table or concentrator table.
Jan 19, 2018 While open pit mining involves extraction of coal from an open pit in the ground, strip mining includes stripping surface layers to reach coal deposits. Contour strip mining, area strip mining and auger mining are other techniques followed in surface mining of coal. In case of strip mining, coal seams are reached by removing the surface above them.

This process involves a cutting head that moves back and forth across a panel of coal. Once cut, the coal falls onto a flexible conveyor for removal.
View MoreIn the process of coal mining, gas outburst is a challenge that must be prevented to guarantee mining safety. Forming gas hydrate in coal can reduce the original gas pressure and delay the concentrative outbursts of gas flow, which is one of the potential technologies to prevent gas outbursts in coal.
