Optimization of mill performance by using online ball and pulp measurements In the platinum industry, by increasing the solid content in the slurry, the product becomes finer. At a higher percentage solid than 73 to 74%, the product becomes coarser again. At this level, a drop in grinding efficiency occurs.

Sep 01, 2013 A grinding circuit simulation combined with ball weal law was used to determine the optimum composition of the make-up ball sizes in tumbling ball mills. It was found that the optimum composition depends on various factors, including the feed size, the product size, the mill diameter and the breakage parameters.

The variation of the parameters of the ball casting’s specific position and the yield rate of the ball casting before and after the scheme is shown in Table 1. It can be seen from Table 1 that the yield of the ball casting process is increased by about 2.8% after optimization.

It was found that the optimum composition depends on various factors, including the feed size, the product size, the mill diameter and the breakage parameters.

The factors which have an impact on milling efficiency include mill internals (profile, length, filling degree, etcetera), grinding circuit parameters, ball type, size and density, mill operating parameters such as velocity, pulp density, percentage of circulating load. The filling degree and pulp density need to be monitored in real time.

Sep 28, 2019 Optimization of the Cement Ball Mill Operation Optimization addresses the grinding process, maintenance and product quality. The air required for classification is provided by another fan. The optimization of this process would yield substantial benefits

Grinding is therefore considered a very benefi cial target for optimization. It is critical to achieve a suitable ore feed size distribution in order to reach high grinding effi ciency and throughput, especially in grinding circuits involving autogenous (AG) or semi-autogenous (SAG) mills. The investment in grinding optimization pays for itself
