Ball mills typically use water or other liquid and additives to help reduce friction and provide cooling during the grinding process. The feed enters one end of the ball mill, and discharges out the other end. Ball mills vary greatly in size, from large industrial ball mills measuring more than 25 ft. in diameter to small mills used for …
Öksüzoglu and Uçurum [27] studied the ultrafine grinding of gypsum ore in a dry ball mill. In their grinding tests, the mill speed was varied from 50 to 90% of the critical speed for gypsum ore
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.
