Process for the separation of rock refuse and coal

This invention relates to a process for separation of rock refuse and products of coal deposits with rock intercalation--the coal contents of which are advantageously less than 50%--into high-carbon and low-carbon parts, or, in a given case, into pure refuse (barren) parts, through use of the heavy-media process.

Crusher Wikipedia

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.
