Here is a formula that allows you to calculate the circulating load ratio around a ball mill and hydrocylone as part of a grinding circuit. For example your ball mill is in closed circuit with a set of cyclones. The grinding mill receives crushed ore feed. The pulp densities around your cyclone are sampled and known over an 8-hour shift, allowing to calculate corresponding to circulating load ...

A clay body that has been ball milled will be more plastic, potentially much more plastic. Ball milling of the body or selected body materials will reduce or eliminate many types of fired glaze imperfections (especially specking, blistering and pin-holing. Milling a glaze will also produce a cleaner fired result with less imperfections.
