Simulation for the Design of Ball Mills for Coal Grinding

The simulation model for tumbling ball mills proposed by Austin, Klimpel and Luckie (AKL) was used to simulate wet grinding in ball mills, and it gave good agreement with experimental results from a 0.82 m diameter by 1.5 m ball mill.

Ball Mills an overview ScienceDirect Topics

The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11 ). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.
