Types of Frequently Used Ball Mills
Ball Mill
Ball mill is the vital equipment for regrinding after primary crushing. It is extensively applied in cement, silicate products, new construction material, refractory material, chemical fertilizer, ferrous and non-ferrous metals beneficiation and glass ceramics industries. It is great choice for dry or wet grinding any kinds of minerals and other grindability materials.
Ball mill is a widely used ultra-fine grinding mill in industrial production. Ball mill has a variety of types, according to different ways of discharging materials, ball mill could be in grate and overfall style. There are also tube mill, cone mill, etc.
Ball mill application
Ball mill is applied to grind ores or other material, normally the size of final products is less than 35mesh.
Feeding applications of the ball mill:
1. One section or multiple sections crushing and screening 2. Crushing, screening, and rod milling 3. Coarse crushing, autogenous grinding or semi-autogenous grinding
Normal feeding material size:
1. For hard ore, 80% should be smaller than 6mm 2. For soft ore, 80% should be smaller than 25mm( some plants could afford bigger material size)
Two types of frequently used ball mills:
Grate type ball mill
At the discharging end of the Grate ball mill, the combination of grating plate with long holes and discharging liftout plate deliver the materials to the hollow shaft opening at the discharging end. The grating plate preserves the steel ball, inclusions and coarse materials.
Overfall type ball mill
The overfall type ball mill has an open-ended discharge opening. Since there is an ore pulp gradient between feeding end and discharging end of the ball mill, the final materials overflow from the hollow shaft. The anti-spin device on the liner plate of the hollow shaft keeps the steel ball in the mill.
Ore experiment of ball mill
There are three types experiment to test mill power. Under most circumstances, one of
