Modeling of a medium speed coal mill - ScienceDirect

This paper presents a coal mill model that considers the effect of coal moisture on its accuracy. This mathematical model is derived through the analysis of mass flow, heat exchange, and energy transferring balances in which all heat input into or output from the coal mill are calculated quantitatively to reduce the number of unknown parameters that need to be identified.

A Comparison of Three Types of Coal Pulverizers

2018-2-1  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 decreases with mill size and remains constant for a given mill diameter.

Pulverised Coal - an overview ScienceDirect Topics

Coal dried with air at 250–350°C for milling in low-, medium- or high-speed mills. Main milling costs are power and replacement of worn parts. Wear depends on fineness of grinding, and on hardness and abrasiveness of coal. Coal and air distribution to burners must be uniform to avoid local reducing zones which encourage slagging.
