The BTM is a lowspeed mill that primarily grinds coal by impact and attrition. The VRM is a medium speed mill that grinds coal by compression and, because of the low coal inventory in the mill and flat grinding surfaces, develops shearing action as well. For both mills a constant centrifugal force is maintained. The speed
In essence, the performance of a pulverizer is a delicate balancing act between the HGI, fuel fineness, and throughput. 1. A typical MPS89 pulverizer found in many coalfired power plants ...

GENERAL. The system for direct firing of pulverized coal utilizes Bowl Mill to pulverize the coal. and a Tilting Tangential Wind box to admit the pulverized coal together with the air required. for combustion (secondary air) to the furnace. As crushed coal is fed to each pulverize by its feeder (at a rate to suitthe load demand), primary air is ...
The coal mills are fed from different bunkers which may not be synchronized in terms of coal grades (Xia, Peng, Zhang, Yang, Chen, 2011). Secondly, coal change in a mill or a boiler is a gradual process which may take several hours (Tuttle, Blackburn, Powell, 2020) to transition from one coal to another. Both unintentional and planned ...

A minimum airtocoal weight ratio of :1 is desired at full load. The ratio could be higher at lower loads (more air per pound of coal). Failure to provide adequate airflow through the mill can result in spillage of coal. The exhauster discharge pressure is an indicator of flow and velocity through the coal piping.
