1 The transmission machinery of cone grate ball mill substitutes large-scale double row self-aligning roller bearing for sliding bearing. It is easy to start and saves energy.

2 The discharge end is cone-shaped. Such design can not only increase the volume, but also separate ores from iron balls when they are carried toward the conic end. The closer ores and iron balls approach toward discharge opening, the smaller diameter of ball becomes. As a result, the grinding action is repeated and enhanced.

3 Cone grate ball mill adopts groove-type circular lining plate that is instrumental in increasing contact areas of iron balls and ores, which enhances grinding action and ore lifting capacity and decreases energy consumption.

It is used for coarse ores
