In the grinding mill, the ore blocks sized >100 mm function as grinding medium. The ore particles smaller than 80 mm but bigger than 20 mm have poor grindability and they cannot be easily ground by big lump ore, so such material is usually called "hardtogrind ore" or "hard rock." To crush the hardtogrind ore, sometimes steel balls ...

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.
