Pulverizer Machine are mechanical devices used for pulverizing, crushing, and grinding a wide variety of materials to varying finesses. Pulveriser is a mill which crushes the fed solid particles between its rollers into powder and many mills has the facility to recirculate large particles and sends out the fine powder particles which can pass through the provided …
coal pulverizer systems supplied by RPI originally designed for low, medium and high- speed pulverization have undergone design upgrades and improvements. These machines include Ball Tube Mills (BTM), MPS mills and Atrita@ Pulverizers, respectively. The Atrita@Pulverizer has been upgraded for better coal fineness and longer service life. BTM
In the suction type, the exhauster is used for lifting the milled coal from the pulverizer to the furnace through a cyclone. The tube mills have a large circular drum, with adequate ball charge, which is rotated at about 70% of the speed at which the ball charge would be held against the inner surface by centrifugal force.

The Operating Principal. P ulverization takes place in the central chamber of the Micron-Master® jet energy mill as the process material is driven at near sonic velocity around the perimeter of the toroidal chamber by multiple jets of air or steam. No grinding media is involved. Size reduction is the result of the high-velocity collisions between particles of …
