— Ball mills have been around since the late 1800's, playing a crucial role in the production of cement. The second-to-last stage of cement production happens in mills, where clinker is ground from a size of several centimeters into pieces less than 100 microns in size. That is smaller than a grain of beach sand! This process consumes ...

There are many types of grinding media suitable for use in a ball mill, including Hardened steel, stainless steel, ceramic, flint pebbles.
— Critical Speed: Critical speed is the hypothetical speed at which the centrifugal force is equal to the gravitational force, and the grinding media starts sticking to the inner shell of the equipment instead of falling freely.Grinding at or close to critical speed of the mill yields a poorer grinding efficiency. The ball mills are mostly operated at 65 …
— The only cylindrical ball mills in common use are those of the grate discharge type, the most important being the Marcy and the Allis-Chalmers mills. Fig. 10 illustrates the construction of the Marcy Ball Mill. The cylindrical shell and the feed and discharge heads are made of cast semi-steel. The hollow trunnions at each end run in …
