Separators or classifiers with higher efficiency give more accurate separation and thereby reduce over-grinding and mill energy consumption. Improved separation also helps increasing the mill capacity, improving the clinker quality – due to better size distribution – and can

Efficiency of separation Precise separation was previously only possible on a laboratory scale, but can now be achieved in large plants because of the SEPMASTER's high performance Upgraded plants show savings in grinding energy of 10 to 20 % on average and production increases of 10 to 25 % for cement raw meal and normal cement Si gnificantly

additives normally improves the efficiency of separation by reducing agglomeration and modifying the behavior of material processed by separator. In this paper an investigation on the morphology of cement particles ground in a typical ball mill with and without chemical grinding aids is described.

Formulas have been developed which use the feed tonnage and assays of the two recovered values to obtain the ratios of concentration, the weights of the three products of separation, and the recoveries of the values in their respective concentrates. For illustrative purposes data from a copper-zinc separation

In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize “just in case”. Well, this safety factor can cost you much in recovery and/or mill liner wear and tear.

8-3 Centrifugal force outward Fc mp 2 Dm 2 (8.1) is the angular velocity, mp is the mass of any particle (media or charge) in the mill and Dm is the diameter of the mill inside the liners. Gravitational force Fg mpg (8.2) The particle will remain against the wall if these two forces are in balance ie.
