In the coal industry, there were also at least six strikes against safety measures (five to oppose a new safety lamp, and one to allow smoking in the coal mine during lunch). (Aldrich p. 90) When safety measures were introduced, workers had to be encouraged, trained, coaxed, and propagandized to use them. They often resisted new measures at first.

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

VG: At best, coal mill safety is not well understood and, at worst, it is ignored. When it comes to coal mill systems, most cement plant operators just presume that the supplier of the equipment knows all of the standards and rules and is 100% capable of making a system that conforms to these and is therefore safe. However, this is not the case.

Fineness is an indicator of the quality of the pulverizer action. Specifically, fineness is a measurement of the percentage of a coal sample that passes through a set of test sieves usually designated at 50, 100, and 200 mesh A 70% coal sample passing through a 200 mesh screen indicates optimum mill performance. The mill wear and the power consumption are increased if the 70% ...
