DIRECT CONNECTED Ball Mill DRIVE. When power exceeds 300 HP a direct connected drive is recommended. This drive is also applicable for lower power requirements if desired. Synchronous motors are preferred, but in some cases wound rotor motors may be used. Motor speeds will vary from 225 rpm to 450 rpm.
Check the wear condition of the steel ball used in the ball mill and monitor it in real time to ensure that they can be replaced in time in case of serious wear. Check the sanitary condition of the equipment. Except for the running part, all other parts of the ball mill should be kept clean at all times. 2. Ball Mill Lubrication System Inspection.
