The ball mill is traditionally the basic technology in a cement plant and is a very reliable machine. It is particularly well adapted to the grinding of products at high fineness, very abrasive products and solid fuels, as well as to a wide range of minerals.
There are two types of mills which are mostly used in cement plants for grinding raw mix viz. Ball mills and VRM. Ball mills Ball mills are essentially fine grinding units capable of grinding material to a fineness say 84% passing 90 microns. The size reduction technique involved here is attrition and impact. In ball mills, Hi-chrome steel .
ball mills, but also from our comprehensive scope of services, ranging from maintenance and OEM spares procurement to the optimization of existing plants. The grinding unit most commonly used for grinding brittle materials, such as cement, is still the ball-filled ball mill. The following types can be found: • single-compartment mills,
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 .
Fig. 8 shows the optimum composition of the make-up ball sizes for various feed sizes as a function of the size reduction ratio, R. Because mixtures of two balls (50.8 mm and 25.4 mm ball) are always found to be optimum, the results are plotted with the ordinate being the fraction of 50.8 mm balls.
