Ball Mill | For Industrial Supplies
The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter. Ball mills are filled up to 40% with steel balls (with 30–80 mm diameter), which effectively grind the ore. The material that is to be ground fills the voids between the balls.

AGGREGATE TOUGHNESS/ ABRASION RESISTANCE AND DURABILITY
The Micro-Deval abrasion test was developed in France during the 1960''s. It is a wet ball mill test. A 1.5 kg graded aggregate sample (retained on the 9.5 mm sieve), 2 L of water and a 5 kg charge of 5 mm diameter steel balls are placed in a stainless steel jar mill and rotated for 2 hours.

The hardness of grinding media ball
When the hardness of grinding media ball is too high, there are two unfavorable reasons for grinding: 1. The grinding media Ball bounces seriously, causing part of the energy loss in the rebound, so the energy of grinding media ball is not more used for crushing, thus affecting the crushing; 2 When the ball and the ball contact with each other
