Optimization of mill performance by using online ball and pulp measurements by B. Clermont* and B. de Haas* Synopsis Ball mills are usually the largest consumers of energy within a mineral concentrator. Comminution is responsible for 50% of the total mineral processing cost. In today's global markets, expanding mining groups are trying
The paper describes a procedure to tune a grinding circuit in order to maximise the economic efficiency of the flotation plant. The optimisation process is performed using a plant simulator based on phenomenological models of grinding and flotation and an empirical model for predicting the minerals size distribution from the ore size distribution of the grinding circuit product.
mineral properties but P changes with mill condition. To characterize impact breakage by grinding balls, laboratory standard tumbling ball mill tests were performed. The optimal values of parameters of Austin model in Equation (1) were estimated for laboratory measured selection function vs. particle size by applying least-square
HPGR are used in various configurations such as pre-grinding, hybrid grinding and finish grinding, among others [4]. This is mainly due to the comminution effect under the action of high-pressure ...

About Us. Shanghai CrusherMining Mining and Construction Machinery Co., Ltd. is a hi-tech, engineering group. We are specialized in the research, development, and production of industrial crushing, powder grinding, mineral processing equipments and other related devices.
Mineral resources all over the world are often heterogeneous and have variable ore properties and ore grade. As a result the ore processed in concentrating plants varies over the life of mines. Consequently the circuits often suffer from bottlenecks typically at the stages of crushing, semi-autogeneous (SAG) and ball milling. Bottlenecks may be remedied with...
