A study on the effect of process parameters in stirred ball mill An experimental study on the fine grinding of calcite powder d50 6216 m using a 075 l laboratory stirred ball mill has been carried
Mill speed was found to have a more pronounced effect on fineness than on net energy consumption Acceptable ranges for ball charge were found to lie from values of 30 to 35 of the mill volume Mill speed ranges that provided acceptable results ranged from 70 to 85 of critical speed

Load of the ball mill affects the productivity quality and energy consumption of the grinding process But sensors are not available for the direct measurement of the key parameters for mill load ML A new soft sensor approach based on the shell vibration signals to measure the operating parameters is proposed in this paper
wet grinding a series of monosize grinding ball mill tests were performed to determine breakage parameters according to the generally accepted kinetic approach of grinding processes A rheological modier polyacrylamide PAM was used to modify solutions viscosity A model was proposed
MILL is the ball milling model that is based on standard Austins models Eqns 14 and and takes into consideration the breakage parameters as does the MolyCop It is mentioned that the MILL model does not take into consideration the operating conditions eg mill diameter ball filling volume and mill speed and a different unit model
