Ball mills for cement raw material and coal equipped with a drying compartment adequately air swept with hot gas (2.5-3.5M/sec above the ball charge), can handle moisture about 8%. Fully air- swept mills (5-6M/sec) can dry up to 12-14% moisture. Grinding Operation Objectives and KPIs: Highly energy intensive unit operation of size reduction in ...

The mill should rotate in the proper direction. The mill gear should be lifted by the pinion causing a downward pressure on the pinion shaft bearing. Mills are made either right or left "hand". There are two methods of identifying the "hand" of the mill.

Control, Process Data & Preventive Maintenance. DCS or SCADA systems control many SAG, rod, and ball mills. These systems are diverse and individualized depending on the equipment and the scope of the system installed. Sometimes you'll see simple metrics, like run status, and other times you'll see more specific metrics like flowrate or RPMs.

Ball Mills can be supplied with either ceramic or rubber linings for wet or dry grinding, for continuous or batch type operation, in sizes from 15″ x 21″ to 8′ x 12′. High density ceramic linings of uniform hardness male possible thinner linings and greater and more effective grinding volume.

The cost of edge drive is low, but the pinion needs to be replaced every 2-5 years. Edge drive is mainly used in coal mills and mills with small power. The girth gear(big ring gear) and pinion are the key of the edge transmission device. Their reliable operation is directly related to the stable production of the mill.

A ball rolling groove 1 c is defined in an inner peripheral surface of A ball screwed nut 1 by a rolling process, not by a grinding process so that a ball screwed nut having small diameters or large leads can be manufactured. The surface of the ball rolling groove 1 c is finished to be sharp without concave and convex by a plastic working by the rolling process, so that the surface is …

The grate plate of the grid ball mill should be replaced when it is worn to be welded and repaired. The gear face of the big gear can be turned over for further use after it is worn to a certain extent. The pinion should be replaced for severe wear.

required ratio should a six pole mote be used. The size of the motor can be determined by the following formula: where P inch is the incher driver power (HP or kW) N o_inch is the requested ouput speed of the mill gear in inching mode N o_mill is the actual output speed of the mill gear in normal running mode P mill_motor is the actual power of the

Cement ball mills can be applied in the open-circuit grinding system and the closed-circuit grinding system. If combined with roller press, the productivity will be greatly improved. AGICO is a professional ball mill manufacturer. Our cement ball mills are both available in dry grinding methods and wet grinding methods.
