Anthracite prospects looking very good Menar Mining Weekly
The prospects for anthracite are looking very good, especially in terms of market value and having demand coming from different parts of the world, says Menar MD Vuslat Bayoglu, who was speakingThere are two types of impact crushers: horizontal shaft impactor and vertical shaft impactor. Impact crushers are suitable for materials that are soft or easily cleaving from the surface. The crusher consists of a fast spinning rotor and beaters attached to the rotor.

Crusher
Crusher. 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 differentIn large coal preparation plants with a capacity of 30 million tons/year, the belt speed can reach 7 m/s and the thickness of the material layer can reach 500 mm.
