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.
Overview. Our GGBS ball mill is a key grinding machine mainly used to process materials by crushing process, and it is widely used in various manufacture industries, like cement, silicate, new building material, refractory material, fertilizer, ferrous metal, nonferrous metal and glass ceramics.
The cement mill is composed of horizontal cylinder, hollow shaft and other parts. The cylinder is long round barrel, and there are grinding media in it. The cylinder is made of steel plate, and there is steel liner fixed on the cylinder.

Cement manufacturing - brief description of a cement mill. Cement clinker is usually ground using a ball mill. This is essentially a large rotating drum containing grinding media - normally steel balls. As the drum rotates, the motion of the balls crushes the clinker. The drum rotates approximately once every couple of seconds.
balls (grinding media) of various sizes. During operation, cement clinker that has been baked in the rotary kiln is fed into the mill through the input shaft. The cylinder rotates at approximately 15 rpm, with the result that the clinker is ground into cement powder by the impact and friction of the grinding media. Schematic diagram of a cement ...

mill, etc). 2. Grinding media The grinding media used are, generally, balls and cylpebs. In compartments of coarse and medium grinding are used balls, and in that of fine grinding, balls or cylpebs. In any compartment, sizes of grinding media must be correlated with the size of the material. Between the balls are formed free spaces (emptiness).
