The grinding matrix was calculated using the selection and breakage functions whereas the classification matrix was defined from the

Wet Grid Ball Mill

Wet Grid Ball Mill

When the ball mill cylinder rotates the grinding body acts on the cylinder liner due to the action of inertia and centrifugal force and friction. It is carried away by the cylinder. When it is brought to a certain height it is thrown off due to its own gravity. The falling abrasive body crushes the material in the cylinder like a projectile. 3.The material is uniformly fed into the first chamber of the mill by the feeding device
