cement mill retention time

Re: MATERIALRETENTIONTIMEIN A BALLMILL& VRM. You could do that by measuring the material flowrate Q[tons/h] through themillas well as the quantity M[tons] of material that accumulates within themill. Theretentiontime, also called residencetime, is the ratio (M/Q) [h] .

The number of stresses can be characterised by the averageretentiontimeof the ground material inside themillif the ball charge grading remains unchanged. The optimalretentiontimedepends 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.
