1. Cylindrical Shell: The ball mill consists of a hollow cylindrical shell that rotates about its axis. The shell is usually made of steel, stainless steel, or rubber. 2. Liners: An abrasion-resistant material such as manganese steel or rubber typically lines the inner surface of the cylindrical shell to protect it from wear due to the grinding action.

What is a ball mill? A ball mill is a size reduction or milling equipment which uses two grinding mechanisms, namely, impact and shear. 1 Unlike other size reduction equipment, such as breakers and jaw crushers, ball mills are capable of producing powders and particulate materials of mean particle sizes within the 750 to 50 micron (µm) range.. Ball …

There are three mill slurry characteristics which you should note. The % fines in the rod mill feed. For the purposes of rod mill performance analysis, "fines" can be arbitrarily defined as particles finer than 75 microns (200 mesh). Rod mill feeds which contain less than approximately 10% fines are good candidates for fines addition testwork.

The procedure used in the experimentation was to pass about 1000 lb of ore through the mill at 1200 lb per hr. The product from the mill was passed through the mill again at 1200 lb per hr until five passes had been made. In each case, samples of the product were taken after 5, 10, 20, 30, and 40 min of operation.
