But in an ironic twist, coal is also responsible for the emergence of fly ash concrete, a new building material that could help curb carbon emissions in the construction industry. Fly ash is produced when coal is burned, and environmental laws in the United States require power companies to trap and properly dispose of it.

The material falls on to the center of grinding plate and under the action of eccentric force, the material starts to move towards the fringe of grinding plate evenly. When moving to the grinding roller bed, the bulky coal would be crushed by the grinding roller while the fine coal would form a material bed where fine coal crushes each other.

Material is prevented from spilling over the edge of the dam ring as both the dam ring height and grinding pressure are adjustable. The ATOX® Coal Mill’s efficient separator allows material that has reached the required fineness to leave the grinding mill and sends oversized material back for further grinding.

A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, 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.

In the cement production line, producing 1 ton of Cement need grind at least 3 tons of materials (including raw materials, fuel, clinker, mixed materials,gypsum).Grinding operation consumes about 60% of total power in cement plants, raw material grinding more than 30%, while coal mill used in cement plant consumes 3%, cement grinding about 40%.
