The optimal ball charge filling ratio for Combiball mills is supposed to be less too. Shoji et al. (1982) investigated the influence of the ball charge filling ratio on the specific power consumption for the grinding of quartz sand. They found a flat minimum at a ball charge filling ratio of about 15%.

In this study, the simulation of grinding of quartz is investigated in order to identify the optimal mill operating parameters. With the use of population balance modeling the specific rate of breakage and the cumulative breakage parameters can be determined from monosize, short grinding time batch tests. The determined

The present study investigates the propensity of predicting ore grindability characteristics and varying pulp densities through acoustic measurements on the Magotteaux ball mill. Specifically, the grinding behaviour of two different mill feeds (model quartz and iron ore) together with solid loadings (50, 57, and 67 wt% solids) were correlated ...

Abstract. An investigation on the kinetics of grinding quartz was carried out in a laboratory stirred ball mill. In this study, the specific rate of breakage S and breakage function B were determined by onesizefraction tests. The results showed that below a certain size, the breakage was firstorder and the breakage functions were normalizable.

Table 1 summarizes the essential results of several investigations related to dry ultrafine grinding tests carried out with quartz and silica particles. Size reduction and agglomeration of SiO 2 particles was primarily investigated by Opoczky [24] in conventional tumbling mills for grinding periods of up to 90 h (h).This author showed that the slowdown in particle size reduction and the ...
