2019-10-1 · Coal preparation is the practice whereby raw coal is modified to a more preferred form to enable its utilization. The methods employed to achieve this preferred modification need to be cost-effective, while processing rate. These numbers thus can translate directly to much higher processing costs for fine coal versus coarse coal
Coal Preparation Process. Crushing & Screening: Raw coal is transported to crushing workshop by belt conveyor. First, it is pre screened by a circular vibrating screen with a sieve opening of 50 mm. +50mm materials and extra large gangue enter the crusher and are crushed to 50mm, and then transported to the coal washing workshop together with -50mm raw coal that under the vibrating screen.
