the ore specific breakage distribution function can be determined from single particle breakage tests conducted using a computer monitored twin pendulum apparatus. when the ore specific breakage distribution function is used in the multi segment, a constant relationship between the breakage rate parameters and mill diameter is observed. thus, the performance of an industrial ball mill

optimization of the design of sag mill internals using high fidelity simulation as a function of distance down the mill and breakage functions for each
numerical and experimental analysis of breakage in a mill using the attainable region approach by matthew
to achieve the desired particle size distribution, milling of such materials is usually the method of choice. since these chemicals are often scarcely available, experimental optimization of milling is not possible. therefore, a model to predict the milling conditions has been developed. the model estimates the rate of breakage function,
milling breakage distribution function paper i of this series showed that the relationship between the inlet and outlet particle size distributions in a roller milling operation can be found by integrating, measuring the efficiency of the tumbling mill as a
study of breakage curves in ultrafine ball mill dry grinding, the breakage distribution function is one of these functions and refers to the way in which the
it has been recognized that the grindability of an ore in a ball mill is a function of both feed and mill parameters: work index, w i largest particle size and size distribution

autogenous or autogenic mills are so called due to the self grinding of the ore: a rotating drum throws larger rocks of ore in a cascading motion which causes impact breakage of larger rocks and compressive grinding of finer particles. it is similar in operation to a sag mill as described below but does not use steel balls in the mill. also
