Ball mills are used primary for single stage fine grinding, regrinding, and as the second stage in two stage grinding circuits. According to the need of customers, ball mill can be either wet or dry designs. Ball mills have been designed in standard sizes of the final products between 0.074 mm and 0.4 mm in diameter.
How Overflow Type Ball Mill Works. Material Feed: The raw material is fed into the mill at one end and travels through the mill by rotation. The feed enters the mill at a specific rate, ensuring a controlled grinding process.; Grinding Process: As the mill rotates, the grinding media crushes and grinds the material into a fine powder. The wet …
choice for wet grinding. Ball and Pebble Mills Both mills utilize tumbling media. Ball mills use steel balls and pebble mills use ceramic or natural rock for grinding. Operating in open or closed circuits, ball and pebble mills are designed for long life and minimum maintenance. Rod mills rod mills are used in both wet or dry
