buildings. The widespread use of aggregates results not only from its general availability but also from economic considerations. The cost of aggregate is not, in itself, a major factor in most applications, but its impact on the use of more expensive components, such as cement in concrete or bitumen in asphalt, is quite essential.

Mill Comparisons—General 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 ...
