Jan 19, 2016· The mills at Sentinel in Zambia are amongst the world''s biggest, with 2 off 40 ft SAG mills complete with 28 MW drives, and 2 off 28 football mills with 22 MW drives. For mines of this size ...
These large coal crushing drive systems are usually rotated by motordriven gearing. A typical application consists of a motordriven primary singlestage reducer that, through a flexible coupling, drives a large open pinion which in turn, meshes with a large ball mill ring (girth) gear that is attached directly to the ball mill.
May 12, 2000· Abstract: The time has come to rethink the approach to mill drive motors because of the growth in size of newer ball mills, the starting torque restrictions of some of the newer mill drive configurations, and the softness of some utility services. This paper looks at the serviceability and economics of five different mill motor options to meet these restraints.

May 02, 2018· An inching drive is used as an auxiliary system to the main drive for a large machine such as a ball mill, industrial kiln, conveyor, or elevator. Its purpose is to turn the equipment at a speed slower than the normal operating speed — typically 1 to 2 rpm, although fractional rpms are also common — and to do so at high torque — typically ...
•The gearbox between motor ball mill had been recently rebuilt. •Two identical ball mills were in place at the plant (1A 1B). •These machines are used to pulverize or crush lime into small particles (dust) that is then made into a slurry and injected into the flue gases to reduce pollution.

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. Industrial ball mills can be as large as m (28 ft) in diameter with a 22 MW motor, [4] drawing approximately % of the total world''s power (see List of countries by ...
The mill used for this comparison is a 44meter diameter by 136 meter long ball mill with a 5000 HP drive motor It is designed for approximately 90 ston per hour This type twocompartment mill is a state oftheart shell supported cement finish mill The torque
Motor The GMD is a drive system without any gear where the transmission of the torque between the motor and the mill is done through the magnetic field in the air gap between the motor stator and the motor rotor. The concept to drive the mill this way is relatively simple using the mill body as motor rotor and mounting the poles there.
