For ball milling you can assume a porosity of about 0.35 to 0.40 the volume of space between the balls and you can normally assume the pulp surface level is equal to the ball charge surface level. So do a crash-stop and measure the volumetric filling of the charge then multiply that volume by 0.35 or 0.40.

Jan 06 2021 Ball mills have been used as the main grinding tool for cement production for over 100 years. Although easy to operate and competitive compared to other technologies the poor efficiency of ball mills has been one of the main reasons for research and development of more efficient grinding processes in recent years.
In the cement industry a ball mill for this application is called a Preliminator mill. . Characteristics of the long mill Longer retention time per particle and the production of a higher percentage of fines in the micron sizes. This is an important consideration in cement clinker grinding.
Cement Ball Mill Structure. When Ball Mill is working raw material enters the mill cylinder through the hollow shaft of the feed. The inside of the cylinder is filled with grinding media of various diameters steel balls steel segments etc. when the cylinder rotates around the horizontal axis at a certain speed Under the action of centrifugal force and friction force the medium and the .
Survival time was assessed following simulated mechanical fatigue in a ball mill. The amount of cement left attached to the band after debanding was also assessed. In addition the effect of sandblasting on the failure rate of 320 first molar bands cemented in 107 patients was examined in a half-mouth trial.
