COAL GRINDING, CLEANING AND DRYING PROCESSOR

摘要

A coal processing mill incorporates integral systems for coarse coal dewatering (5), grinding (9), injection of peptizing agent (11) into the ground coal stream before it enters an agitation zone (12) where the peptizing takes place, passing the treated coal and the peptized clay and ash through a separating valve (17) and passing the separated coal on to final drying (31). In other embodiments, ash and pyrites of much higher density than coal are separated from coal and the coal can be fired.
