ABSTRACT:
A division head for a tubular grinding mill for controlling the level of material being ground in the upstream compartment of the mill. The division head is formed by a plurality of hollow pie shaped segments covered on the upstream side by grates which permit material to flow into the division head and liners and on the downstream side. A partition divides the pie shaped segments into radially inward sections and a radially outward section. Material within the radially inward sections flows out of the division head into a downstream compartment of the mill through a central discharge cone. Some of the radially outward sections are flow connected directly to the radially inward sections through an opening in the partition dividing the pie shaped segments. Dampers are provided for controlling flow of material through the opening connecting radially outward sections with radially inward sections. By controlling flow out of the radially outward sections, flow into those sections is controlled and the level of material in the upstream mill compartment can be controlled.
