#0183;#32;Mechanisms of slowingdown effect in fine wet grinding were hypothesized to involve the different roles of slurry rheology in different grinding regimes. They are reduction of particle capture efficiency due to fluid drag for Regime I, reduced efficiency of stress transmission due to ball coating by particle layer for Regime II and reduction of ball collision frequency due to ball adherence for Regime III.
In previous studies, the analysis of ball mill #176; operating parameters and their effects on breakage phenomena has been limited to homogeneous materials. Though these #223; studies have proven to be an asset in predictions of product size distributions and mill scaleup, they have not addressed the primary role of grinding, liberation. I

Summary: An investigation was made of the effect of slurry consistency on the behavior of wet grinding in a batch laboratory ball mill. Using the wellknown batch grinding kinetics model in analyzing the test data, it was found that wet grinding of quartz and copper ore gave nonfirstorder acceleration of breakage rates at low slurry densities (geq60 volume % solids).
Monosize grinding tests in a laboratory ball mill were performed to determine breakage parameters, with different ball diameters. A model was developed to determine the specific rate of breakage in terms of grinding, rheology, breakage parameters, relative the positive effect of the grinding of particle mobility is reduced due to

#0183;#32;The effect of mill speed ratio k on the grinding ball motion was investigated using the described mill test rig. The other parameters were set to the standard values as given in Table 1. No mill feed was added to the grinding chamber. The resulting grinding ball
Effect of ball load and size distribution on grinding and . An industrial test work was performed to analyse the effect of applying a lower ball load and a finer ball size distribution in the second compartment of a KHD Humboldt Wedag #174; ball mill on grinding and classification performance of a hybrid high pressure grinding roll (HPGR)/multicompartment ball mill cement grinding circuit.
The effect of grinding conditions was studied by changing the solids feed rate, the feed slurry density, the weight of ball charge and the mill rotation speed. The optima of these variables in terms of energy consumption and production rate of fine fractions were determined individually for each tested ore.
