Grinding mills: ball mill & rod mill design & parts common types of grinding mills include ball mills and rod mills. this includes all rotating mills with heavy grinding media loads. this article focuses on ball and rod mills excluding sag and ag mills. although their concepts are very similar, they are not discussed here. photographs of a glass ended laboratory ball mill show action of ball.
Important advances have been made in the last 60 years or so in the modeling of ball mills using mathematical formulas and models. one approach that has gained popularity is the population balance model, in particular, when coupled to the specific breakage rate function. the paper demonstrates the application of this methodology to optimize solids concentration in ball milling of an iron ore.
Jan 01, 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)..
