MATERIAL RETENTION TIME IN A BALL MILL VRM - Page

2010-8-11  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].

Optimization of continuous ball mills used for finish ...

The optimal retention time depends not only on the feed material and the desired comminution result but also on the ball charge filling ratio and particularly on the L/D ratio. On the basis of the present results and considerations, a specific optimisation of ball mills in semi-finish-grinding plants can be done.

Clinkerization - Cement Plant Optimization

Length and diameter of kiln is decided for the required capacity throughput. Main factors dictating size of kiln are the retention time (25-30 minutes) of material in kiln, degree of filling (10-17%) and thermal loading of burning zone (2.8-4.8 x 10 6 kcal/h/m 2). Pre-calciner kilns are shortest in length, as 90-95 % calcination is completed ...

Ball Mills - an overview ScienceDirect Topics

8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.
