cumulative rates ball mill model

cumulative rates ball mill model

Sep 01, 2013 · The cumulative rates model in is a simple population balance model based on the assumption that only one function is necessary to describe grinding kinetics inside the mill, as illustrated in . This function is the cumulative breakage rate function, which is defined as the rate per unit mass that a given species coarser than a given size breaks to below that size [6]

modeling breakage rates of coarse particles in ball mills

Jun 01, 2009 · The model has demonstrated to be able to predict non-first-order rates of breakage of coarse particles in ball mills with good agreement with experiments. It has also been able to produce fair to good descriptions of breakage rates of particles in intermediate to finer size ranges, although it was not the original aim of the present work

a specific energy-based ball mill model: from batch

Feb 01, 2016 · For continuous ball mill operation, the mass flow rate of mill product, P i, is the result of mill ground product, H i and discharge rate, D i, expressed by Eq. (6) : (6) P i = H i · D i The product size distribution can be calculated as a ratio of the mass flow rate by size ( P i ) to the total mass flow rate

Nov 01, 2013 · If this alternative modeling scheme is used with batch ball-mill grinding, or plug flow transport, the grinding model reduces to (7) R i t = R i 0 exp − z i t p i where z i (min − 1) is the cumulative breakage rate parameter which gives the rate of breakage of particles coarser than size i, and it replaces the breakage rate and distribution parameters as a single breakage parameter; p i corrects for non-first …

how to improve ball mill performance

Oct 25, 2017 · Based on the energy expended in the ball mill, the production rate of new product size material (tonnes/h) equals the amount produced per unit of energy applied (tonnes/kwh) times the rate at which energy is applied (kwh/h). The rate at which energy is applied is the power draw of the ball mill
