19/10/2007 The use of first-order grinding kinetics in a simulation model will always predict some small percentages of material in the top size intervals of the mill product. However, it is often found in wet ball milling that instead of the predicted small values the experimental result is actually zero percentage.
More01/02/1993 Laboratory ball wear simulation In order to validate the wear model, a series of simulation tests were completed using published ex- 312 P. Radziszewski, S. Tarasiewicz I Ball mill wear perimental data [18, 19]. The objective of these sim- ulation experiments was to determine the applicability of the wear model to reproduce laboratory data as a function of ball and material hardness as well as grinding (wet/dry) conditions. Liner wear
More20/07/2017 A wet ball mill with 40% volumetric loading and 2.44 meters diameter inside liners was chosen as a test mill. This choice means that the only efficiency factor which is non-unity will be for the mill in open circuit and this factor is equal to 1.2 (Rowland and Kjos, 1978) . The size in micrometers that 80% of the weight of the feed and product passes, F80 and P80, were kept constant for each grinding simulation
