Mill Steam Inerting System Review and Performance Validation
During a ball tube mill start-up, Riley Power Inc. recommends a specified steam flow rate to be introduced and mixed with the primary air entering the mill to establish an inert atmosphere in the mill. During mill shut down, the same inerting process starts when the coal feeder is stopped or mill coal inventory reaches a certain level.
A Comparison of Three Types of Coal Pulverizers
The BTM is a low-speed 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

Derivation and validation of a coal mill model for control
The input mass flow of the raw coal to the mill is difficult to measure as well; typically, the conveyor belt speed is used for this purpose. Additionally the varying coal quality, e.g. Hardgrove Grindability Index (HGI) and moisture, of coal fed to the mills varies, and general mill wear cause parameter changes (Fan, Rees, & Parker, 1997).
