How Many Types of Ball Mill? - JXSC Machine
1. Overflow type: discharge ore through the hollow shaft. When the ore discharge surface is higher than the slurry surface, the finished product is discharged and the ore is automatically discharged by gravity, thus the overflow ball mill saves energy. 2. Grate discharge ball mill: the ore is discharged through the grate plate.
