The Overflow Discharge mill is best suited for fine grinding to 75 – 106 microns.; The Diaphram or Grate Discharge mill keeps coarse particles within the mill for additional grinding and typically used for grinds to 150 – 250 microns.; The Center-Periphery Discharge mill has feed reporting from both …
What are Mill Balls Made of?
They are made of steel and come in different sizes and shapes, depending on the application. Steel balls are very durable, have high density, and are resistant to wear and tear. They are also relatively cheap, making them a popular choice in the mining industry, where large quantities of mill balls are required. 2. Ceramic Balls.
