Ball Mills. Ball mills have been the primary piece of machinery in traditional hard rock grinding circuits for 100+ years. They are proven workhorses, with discharge mesh sizes from ~40M to <200M. Use of a ball mill is the best choice when long term, stationary milling is justified by an operation. Sold individually or as part of our turnkey ...
In industrial applications, the inner surface of the mill is lined with mill liners protecting the steel body of the mill and incorporating mill lifters which help to raise the content of the mill to greater heights before it drops and cascades down [36]. There are three types of grinding media that are commonly used in ball mills:
Secondly, many efficiency factors are already required to correlate the work indices of the lab Bond ball mill with industrial ball mills; changing to a different type of mill with different geometries, different operating principles and different types of stressing conditions present makes the application of a stirred media mill efficiency ...
