OWNERS AND OPERATORS MANUAL FOR BICO UA V-BELT PULVERIZER A grooved revolving plate is rotated against a grooved stationary plate to produce the grinding action. The space, which separates the plates, when they are adjusted for operation, determines the fineness to which the friable material is reduced.
Pulverizers efficiently reduce aggregate, mineral or coal sample particle sizes using grinding plates, hammermills, or centrifugal impact. Grinding Mills include Ball Mills, Mortar Grinders and various types of Cutting Mills and Beater Mills fall into this category.
The point we are trying to make is this: coal pulverizer capacity is a specified fuel grinding capability or throughput at a certain HGI (coal grindability index) and also based on raw coal size, moisture and desired fineness level. These factors are significant and must all be taken into
dries coal in the grinding zone and carries pulverized coal particles upward into a classifier. Fine pulverized coal exits the outlet section through multiple discharge coal pipes leading to the burners, while oversized coal particles are rejected and returned to the grinding zone for further grinding.
Pulverized coal mills with throats that are too wide will have corresponding low throat velocity in the mill grinding zone that contributes to excessive coal rejects and fires. This is an example ...
