the desired motor power and drive rating, the maximum design mill speed, and the maximum design ball charge volume (Barratt, 1989). For single pinion and dual pinion drives, with 21 MW now a distinct possibility, the probability of pinion changes to a higher mill speed should always be considered when set-

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.

2 GEARLESS MILL DES The gearless mill drive eliminates ring-gear, pinion, gearbox, coupling, motor shaft and motor bearings, used within a conventional mill drive system. By mounting the rotor poles directly onto the mill, the mill itself becomes the …

Two Common Permanent Magnet Energy-Saving Solutions: (1) Permanent magnet direct drive motor to drive pinion instead of asynchronous motor + reducer; the 2 nd type of ball mill which uses a three-phase synchronous motor, can not be replaced by permanent magnet motor;(Ring type direct-drive permanent magnet motor can be used for modification) (2) Ring type direct …

The inching drive, also known as a barring or auxiliary drive, is an important component of any mill or kiln installation. It is used for maintenance and inspection purposes, as well as an emergency auxiliary drive to keep kilns rotating when the main motor fails. This paper covers what data the end user needs to

Oct 22, 2016· Ball Mill SPEED REDUCER DRIVE. This is essentially a direct connected drive permitting the use of higher speed motors. The motor shaft is connected to the high speed shaft of a reducer by a flexible coupling and similarly the low speed shaft and pinion shaft are coupled.

The mill used for this comparison is a 4.4-meter diameter by 13.6 meter long ball mill with a 5000 HP drive motor. It is designed for approximately 90 s.ton per hour. This type two-compartment mill is a state- of-the-art shell supported cement finish mill. The torque and time requirements of the mill with the ball

Benshaw has in excess of 100,000 HP of installed ball mill motor control base, and 30 years of experience with ball mill motor controls. Using this experience, Benshaw has pioneered the innovative technique of using a low voltage AC drive to power a medium voltage application … providing a reliable, cost effective solution for ball mill control.

These large coal crushing drive systems are usually rotated by motor-driven gearing. A typical application consists of a motor-driven primary single-stage 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.

Steel Ball Mills & Lined Ball Mills. Particle size reduction of materials in a ball mill with the presence of metallic balls or other media dates back to the late 1800's. The basic construction of a ball mill is a cylindrical container with journals at its axis. The cylinder is filled with grinding media (ceramic or metallic balls or rods ...
