How a Grate Discharge Ball Mill Works 911 Metallurgist

How a Grate Discharge Ball Mill Works 911 Metallurgist

Each time the grate enters the mill charge, the horizontal force of the load in the mill deflects the grate. This stretches the rubber and forces any large material caught in the grate opening along through the grate slot. As the grate leaves the charge, the rubber assumes its original shape. This diaphragming action works the large particles ...
