Six different conditions of solids concentration and three levels of ball loading were assessed.

## Ball Mill: Operating principles, components, Uses,

The degree of milling in a ball mill is influenced by; Residence time of the material in the mill chamber. The size, density and number of the balls. The nature of the balls (hardness of the grinding material) Feed rate and feed level in the vessel. Rotation speed of the cylinder. Several types of ball mill exist.Measurement and modeling of residence time distribution of,,AbstractComparison between anticipated and measured mean residence time (MRT) along with analysis of the shape of residence time distribution (RTD) curves provides the most useful and valid information about mixing properties within a ball mill operating at industrial scale.MATERIAL RETENTION TIME IN A BALL MILL & VRM - Page 1 of 1,Aug 11, 2010 · 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] .
