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 0.2mm) or the second stage grinding.Overflow ball mills adopt the overflow principle to discharge the qualified material slurry higher than the discharge port naturally.

The difference between them is only that there is no fan-shaped grid plate device in the discharge part of overflow type. The slurry of overflow type ball mill is discharged automatically through ...

The main component of the overflow type ball mill is a cylinder with a small diameter and a large length. It is supported by a rolling bearing and slowly rotates through a transmission mechanism. The material is fed from the feeding end of the cylinder.

Grate ball mill (grate discharge ball mill) is a ball milling machine used to grind various ores and other materials. Grate type ball mill is a traditional ball milling equipment for forced ore discharge by ore discharge grate..
