Discrete Element Methods (DEM) is a numerical tool consolidated to the simulations of collisions in particulate systems. In this paper, the method was used to study the collisions between grinding media and grinding media and walls in ball mills, which is the most used unit operation in clinker grinding, the majority component of the cement. Amongst the variables that affect the dynamics of ...

Re: MATERIAL RETENTION TIME IN A BALL MILL VRM. You could do that by measuring the material flowrate Q [tons/h] through the mill as well as the quantity M [tons] of material that accumulates within the mill. The retention time, also called residence time, is the ratio (M/Q) [h] . The flowrate Q could be measured from the production P [tons/h ...
