ball mill system design consideration

Design considerations for large diameter ball mills

The effect of ball size must be properly taken into account in the scaleup. A design method that combined the kinetic scaleup findings and the transport of material through the mill has been developed. A computer program involving kinetic and transport considerations has been tested and found to be satisfactory for mill design purposes.

Pharmaceutical Grinding Mills with Classifier Milling Systems

The ball mill usually contains differing sizes and diameters of balls. It can also have wet or dry designs. Ball mills actually reduce the size of pharmaceutical agents through impact and attrition. Initially the active ingredients are flattened by the colliding balls. The ball mill is an effective tool in grinding delicate brittle and sticky materials.

Grinding in Ball Mills Modeling and Process Control

The design of a ball mill can vary significantly depending on the size the equipment used to load the starting material (feeders) and the system for discharging the output product. The size of a mill is usually characterized by the ratio length to diameter and this ratio most frequently varies from 0.5 to 3.5.
