SIZE REDUCTION | PPT
26. Working : 60% cylinder filled with material. Remaining balls are introduced to cylinder. And closed it with lid. Mills are allowed to rotate on axis. Speed of rotation play important role. At low speed, balls roll over each other and size reduction not occur at optimum level. At high speed, ball will stick to the wall of cylinder and no size reduction …Web

Principle of fluid energy mill. It is based on the effect and attrition idea. The inlet and exits are connected by a classifier, which stops particles from passing until they are fine enough, as shown in Fig. 2.5. (a). It aids in the size and shapes determination of particles. The efficiency of air/inert gas is directly proportional to its speed.Web
