Chat OnlineA ball mill grinds material by rotating a cylinder with steel grinding balls, causing the balls to fall back into the cylinder and onto the material to be ground.The rotation is usually between 4 to 20 revolutions per minute, depending upon the diameter of the mill.
Chat OnlineMaterial retention time in a ball mill vrm.The material m accumulated within the mill could be observed by measuring the level of the material within the mill, deducting the volume occupied by the balls and assuming a reasonable value for the material density.Alternatively, you might empty the mill and weight what comes out.
