In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize "just in case". Well, this safety factor can cost you much in recovery and/or mill liner wear and

selected due to its relationship with mill ball filling percentage. Surface Load Photograph Mill load had not been heterogeneous after turning it off, because of the mill rotational movement and density differences between metallic balls and stony load. As a result, the mill was spun slowly via the inching motor in order to get a more homogenous internal load. Then, the surface load was meshed

A VSI mill throws rock or ore particles against a wear plate by slinging them from a spinning center that rotates on a vertical shaft. This type of mill uses the same principle as a VSI crusher.. Tower mill. Tower mills, often called vertical mills, stirred mills or regrind mills, are a more efficient means of grinding material at smaller particle sizes, and can be used after ball mills in a

ations have recognised an opportunity in the relationship between feed size and mill performance and manipulate feed size to obtain efficiency improvements (Morrell and Valery, 2001). The specific energy does not just depend on ore competence but also on factors such as feed size and ball load (Morrell, 2004). The ore competence is usually characterised by pilot plant testing, lab testing an
