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] .

Optimization of continuous ball mills used for finish
The number of stresses can be characterised by the average retention time of the ground material inside the mill if the ball charge grading remains unchanged. 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.

Cement grinding Vertical roller mills versus ball mills
As less grinding energy is used in producing a cement of a required fineness in an OK mill and the retention time in the mill is shorter, the product will not be heated up as much as in a ball mill. This means that a lower degree of dehydration of the gypsum must be anticipated. This may not be a problem if the gypsum is sufficiently

Jan 07, 2015 CEMENT INDUSTRY Cement Mill Notebook QATAR NATIONAL CEMENT COMPANY DOHA-QATAR 2010 [email protected] The main influencing factor on the retention time is the mill length. Therefore, the ratio of length to diameter (L/D) of a mill is an important factor for an optimal design of the mill. L/D = 3.0 3.6 for closed circuit.
