Coal mining Coal preparation | Britannica

Levels of cleaning. Coal preparation results in at least two product streams, the clean coal product and the reject. Generally, five levels of preparation can be identified, each being an incremental level of cleaning over the previous one: Level 0: At this level, no coal cleaning is done; ROM coal is shipped directly to the customer.

Pulverizer Wikipedia

A control circuit monitors the coal level in the mill, and controls the speed of the raw coal feeder to maintain it. Maintaining the coal level in the mill offers a builtin capacity cushion of pulverized fuel to take care of short interruptions in the raw coal circuit. The mill is pressurized and the airtightness is ensured by plenum chambers ...
