  • Pulverizers Cage Mill Crushers Stedman Machine Company

    Cage mills are mechanical impact machines that crush grind or pulverize a variety of materials to specified degrees of fineness. They can be configured in two four and six row designs depending on the specific application needs and are commonly used to pulverize industrial materials including coal and agricultural limestone. There is one important characteristic of coal that decides the type size and power required for pulverizing. This is the grindability of coal and is denoted by the Hardgrove Grindability Index (or HGI). Grindability in general is a function of the grade of coal. Sub-bituminous coal from the Indian sub-continent has an index near fifty.

    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 a high-performance mill featuring significantly improved low-load operation and load change capability.
