Analysis of particle behavior inside the classifier of a Raymond Bowl
A mill is a device that is used to pulverize coal into the desired size distribution. A diagram detailing the components of a mill is included in Fig. 1. The as received coal is loaded into the mill, using a gravimetric coal feeder. Upon entering the mill, the coal falls into a large steel bowl which is mounted to a drive system causing it toWhat is claimed is: 1. In a bowl mill having a substantially closed separator body, a rotatable grinding surface mounted for rotation in a first direction within the separator body and upon which pulverization of material is effected, an annular passage formed between the separator body and the circumference of the rotatable grinding surface, the Bowl mill with primary classifier assembly Combustion
