Coal powder processing - Grinding Mill

Technological Process. Pulverized coal to 150-200mesh and sprayed into the furnace can burn more fully. Impurities can be effectively removed in the grinding process, and the burnout rate is higher. (1) Grinding Stage: Moist coal should be dried first, and then sent to the main grinding room for grinding.
