Overflow ball mill is also called overflow type ball mill. It is a kind of wet ball mill grinder, frequently used in the material refine grinding (finished material is lower than ) or the second stage ball mills adopt the overflow principle to discharge the qualified material slurry higher than the discharge port naturally.
A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.
Your Ball Mill reflects years of advancement in grinding principles, materials, and manufacturing techniques. It has been designed with both the operators and the erectors viewpoints in mind.

The grate discharge ball mill is also called grate ball mill. It is often used in the first stage of twostage grinding to dry or wet grind various ores and other grindable materials. Compared with overflow ball mill, grate ball mill is a type of ball mill grinder that can realize forced ore discharging by grid lining plate and fanshaped chamber.
The grate holds the balls inside the mill but allows the slurry to pass through, and it is then pumped out of the mill by the pulp lifters. This is different to an overflow mill which holds the slurry and balls inside until the slurry builds up to a level at which it is possible to overflow out of the discharge trunnion.
