Grinding Mill Feed Chutes. Grinding mills for the mining, cement and rock products industries may he furnished with or with-out mill feeders, as desired. Feed chutes can he any one of several types which convey the material into the mill. None of the feeders described here weigh or proportion materials fed to the mill.
the mill shell. Drive motors In the case of ring gear drives, either wound rotor induction motors or synchronous motors can be used. Induction motors Wound rotor induction motors are usually equipped with starters for a controlled ramp up of mill speed with modest inrush currents. Motor speeds usually require the appli-cation of a speed reducer.
Horizontal mills, almost exclusively ball mills, are widely used in the cement industry to grind materials into the required size. If the equipment is not operating at optimum efficiency, the result will be excessive energy and maintenance costs, reduced throughput and increased downtime.
