  • Advantages of Gearless Motor Drives in Large Ore Grinding

    Gearless motors up to 22 MW are in service in many of these ore processing plants. Gearless motor drives are also known as “ring motors” or “wrap around motors.” The motor consists of a large number of magnets placed circumferentially on the shell of the grinding mill. This is similar to the rotor of a conventional motor.grinding mill dimensions mechanical drive,Ball mills are commonly used in the manufacture of Portland cement and finer grinding stages of mineral processing, one example being the Sepro tyre drive Grinding Mill.

    1). A 2 pole (3600 RPM) motor with a 4" drive wheel will produce a surface speed of about 3700 sfm. 2). A 4 pole (1800 RPM) motor with a 6" drive wheel will produce a surface speed of about 2800 sfm. This is why 6 and 8 pole motors are not very useful without some counter-shaft ratio to up the speed.Drive Solutions for the Global Mining Industry,All three grinding mills are driven by synchronous motors of identical ratings.
