Mitsubishi Power, Ltd. Pulverizers

To efficiently combust coal, it needs to be pulverized into fine particles (100μm) before being placed in a boiler. A pulverizer (coal pulverizer) is installed for this purpose, and pulverizes pieces of coal several centimeters in diameter down to fine particles. The pulverizer includes pulverization, drying and classification functions.

Pulverizer - Wikipedia

In order to avoid excess sweeping of coal from the mill, only part of the primary air, directly proportional to the boiler load demand, is passed through the mill. Furthermore, to ensure sufficient velocity of pulverized fuel to avoid settling in the pipes, an additional quantity of primary air is fed into a mixing box on the raw coal circuit.
