Apr 26 2019 A ball mill is a form of grinder that is used to blend or grind materials for use. It is a cylindrical device mainly for grinding material such as iron ores ceramic raw materials glass steel etc. The ball mill works on impact and attrition principle. Its impact is the size reduction given that the balls drop from almost the top of the shell.

Raw Material Ball Mill

As rotation continues steel balls inside the drum compartment are lifted up as high as centrifugal force and friction take them before falling back down on the materials. During this process a large crushing force acts on the materials grinding them to finer sizes. The finely ground particles move out of the drum via a classifier.
