Apr 28, 2020 significant savings of time for calculation of the filling degree the ball mill; to avoid the production stoppages. Based on the advantages of this service, it can be concluded that the main one is the reduction in the number of production stoppages, i.e. the saving of time.Calculation of the filling degree the ball mill with grinding media. For the ball mill efficient operation, it is necessary to constantly maintain the required loading level by the grinding media. It is very important to correctly and accurately measure the grinding media quantity in the mill. Measurements provided in the worked-out mill (without crushed material) by measuring the following parameters Indeed, as explained previously, at a mill stop, the measurement of ball charge filling degree could be undertaken and will provide the static media charge angle (static 143 ). An online measurement of the similar angle (dynamic), when the mill is running, provides information about the dynamics of the charge.
