Abstract: The ball mill is the important equipment in the mining industry, with the development of the macro-scale ball mill, and is more difficult of liner’s wearing,installation and taking apart. The service life which raises a liner will prolong the production period that the ball mill, influencing an economic benefit of the concentrating mill. Therefore, it is of great significance for dynamics simulating on the grinding …

Focus on sand and aggregate information. Pay attention to industry trends, value information, and take advantage of new business opportunities.
It has been emphasized that, as the purpose of grinding is to produce fine particles, the mill design and scale-up work should be based mainly on the F * parameters. Moreover, it is not correct to regard the S * values to be independent of the mill design and operating variables as a general rule, especially for a fine analysis of the performance of the grinding systems
Learn MoreThe following are factors that have been investigated and applied in conventional ball milling in order to maximize grinding efficiency: a) Mill Geometry and Speed – Bond (1954) observed grinding efficiency to be a function of ball mill diameter, and established empirical relationships for recommended media size and mill speed that take this factor into account. As well, mills with different

Learn MoreThe results of discrete element method simulation were compared with actual grinding experimental results. The grinding rate constant K can be expressed as K=a exp(bn), where n is the rotation speed. To investigate the correlation between K and the simulation results, a new factor, the calculated force, was defined as F cal =average force acting on a ball coordination number
