The type of material you want to grind is crucial in determining the type of ball mill to use. Some materials are more abrasive than others and require a specific type of mill that can withstand wear and tear. 2. Particle size The particle size of the material you want to grind will determine the size of the ball mill you need.

Ball mills are usually either of the grate ( diaphragm) or overflow type. Ball Mill Components Ball mills consist of the following components: Inlet crushed ore is fed to the ball mill through the inlet. A scoop ensures the feed to the mill is constant. Discharge reduced feed exits the mill through the discharge. Ball Mill Components

How a Grate Discharge Ball Mill Works Here I try to explain how ground slurry is discharged from a grate ball mill (or SAG). How it works is, the slurry flows across the grate as it would a screen panel. On the other side of the grate/screens are veins like a pump impeller. As the mill turns/rotates the slurry is "pumped" out and discharged.

Ball mill. According to the discharging way, ball mills can be divided into two types: grate discharge type and overflow type. a. Grate discharge ball mill. The grate discharge ball mill can discharge material through a sieve plate, with the advantage of the low height of the discharge port, which can make the material pass quickly.

W for rod and ball mills shall be taken as the weight of the rod or ball charge, the weight of the pulp is to be ignored. For pebble mills therefore W is to be calculated on the basis of the bulk weight of the pebbles.

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.
