If the mill is restarted without first removing the hot coal, an explosion can occur when particles are suspended and exposed to the in-rushing combustion air. Even in routine mill shutdowns, there is a danger that any residual coal left within the mill will oxidise, and may explode as the mill is restarted.
The coal mill adopts an edge driving system, is driven by the motor through the reduction gear and large and small gears. Raw coal is fed into feeding device of coal mill in cement plant, the hot air with temperature about 300 ℃ through the duct into the feeding device, there is a special lifting board in drying storehouse board will raise the raw coal, and helps the raw coal …

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

Pulverizer Mills are used in ores, coal, clays and cement - of fertilizers and agricultural limestone - of slags, pigments and other minerals. This type of mill consists of two rings separated by a series of large balls, like a thrust bearing. The lower ring rotates, while the upper ring presses down on the balls via a set of spring and adjuster assemblies, or pressurised rams.
Attrittors. Attrittors are used for wet grinding limestone for flue gas desulphurization. The process uses limestone feed stock of approximately 6mm in size and wet grinds the limestone to 95% minus 325 mesh. The Attritor operates in continuous processing mode. The grinding circuit includes the separation tank, mill recirculating pump, mill ...
