Fig.1: Cascade Operation in Ball Mill (a) Low Speed (b) High Speed (c) Correct Speed: The material to be ground is fed from a hopper at a 60° angle and the product is discharged through a 30° angle. As the shell rotates the balls are lifted on the rising side of the shell and cascade down (or drop down onto the feed) from near the top of the ...
Produced strong vibration and sound and less in case of rubber ball usage. Can not reduce soft, tacky, and fibers materials; Wear occurs inside the cylinders hence chances of possible contamination are high; Less capacity, do not handle the large quantity. Ball Mill Price. Ball Mill Price in India ranges from 53,000 to 1.20 Lac depends on the size.

This ball mill training course is designed to train each participant on the overall technology, operation and maintenance of the ball mill cement grinding system. The training course focuses on the latest best practices for the operation and maintenance of ball mill systems to allow for optimal cement production, energy savings, reduced ...
If a ball mill uses little or no water during grinding, it is a 'dry' mill. If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills.
