The principle of Attritor dry grind processing is achieved by an expanded moving bed of media. This condition is described as kinematic porosity. The dry particles are subjected to various forces such as impact, rotational, tumbling, and shear; therefore, micron range fine powders can be easily achieved.

Mafezzoni (1996) described this developed model as more of a knowledgebased model than a control model. Control of coal mills up to a certain extent has been developed (Fan and Rees, 1994). A team from ABB designed a coal mill model for monitoring and control based on Fan and Rees principle using 3 particle size (Mercangoez et. al. 2011).

Coal Pulverizer Purpose. Irrespective of the machine used to pulverize the coal, all coal pulverizers have a similar purpose. Coal pulverizers are used to dry, grind and classify. Drying is achieved as hot gas passes through the pulverizer and removes moisture from the pulverized coal. The hot gases used should have a low oxygen content, this ...

Fineness is an indicator of the quality of the pulverizer action. Specifically, fineness is a measurement of the percentage of a coal sample that passes through a set of test sieves usually designated at 50, 100, and 200 mesh A 70% coal sample passing through a 200 mesh screen indicates optimum mill performance. The mill wear and the power consumption are increased if the 70% ...
