Ball Mill | Henan Deya Machinery Co., Ltd.

The final stages of comminution are performed in tumbling mills using steel balls as the grinding medium and so designated "ball mills.". Since balls have a greater surface area per unit weight than rods, they are better suited for fine finishing. The term ball mill is restricted to those having a length to diameter ratio of 1.5 to 1 and less.
