Ball Mill an overview ScienceDirect Topics

Ball mills give a controlled final grind and produce flotation feed of a uniform size. Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel.

Practical 1 : Ball Milling TF Lab 1

23/12/2013  Particle size, number of balls, particle density, hardness, number of media used, time of grinding, and speed of the ball mill (rpm) are factors which will affect the process of milling. Size: The smaller the media particles, the smaller the particle size of the final product. Meanwhile, the size of grinding media particles should be larger than the material to be ground.

Very large tonnages can be ground with these ball mills because they are very effective material handling devices. Ball mills are rated by power rather than capacity. Today, the largest ball mill in operation is 8.53 m diameter and 13.41 m long with a corresponding motor power of 22 MW (Toromocho, private communications).
