The following equation is used to determine the power that wet grinding overflow ball mills should draw. For mills larger than 3.3 meters (10 feet) diameter inside liners, the top size of the balls used affects the power drawn by the mill. This is called the ball size factor S. Rod and Ball Mills by C.A. Rowland and D.M. Kjos @ Allis-Chalmers

Our GMD eliminates all mechanical components of a conventional mill drive system, such as ring-gear, pinion, gearbox, coupling, motor shaft and motor bearings: By mounting the rotor poles directly onto the mill, the mill itself becomes the rotor of the gearless motor.

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. As a result the motor does not have a separate (motor) rotor and thus no separate (motor) bearings. The number of poles is based on the required speed of the mill.

The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum ‘chunk size’, product size as P80 and maximum and finally the type of circuit open/closed

Mill Power Draw Models. The mill power draw models are used to predict how much power will be consumed by a particular type of mill, mill geometry and set of mill operating conditions. This power is transferred to the ore and used to predict the throughput when combined with the specific energy consumption models.

Typical motor speeds are either 4 or 6 pole, i.e. 1750 rpm or 1170 rpm for 60 Hz applications and 1450 rpm or 970 rpm for 50 Hz applications. The advantage of using a four pole motor allows for a smaller footprint and a smaller brake if required by the process. A six pole motor will be larger but will have a

Feb 23, 2018· Before drawing any conclusion, check the line-to-line voltage. If it is more than 10% above the motor rated voltage, it could be the cause of the high full-load speed and possibly the high current. An open rotor can cause a pulsation in the output torque of a motor as the open rotor bar passes under each phase of the motor winding.

The poles of the gearless or synchronous motor (also called wrap-around motor or ring motor) are directly installed on the pole flange of the mill shell, turning the mill body into the rotor. The stator is then wrapped around the mill. The gearless motor is fed by a cycloconverter which has a rated output frequency of around 5 Hz for the GMD drive.

I am aware that the synchronous motors on ball mills are often used to correct the facility PF. The biggest mill I've seen was around 30,000hp with the field poles mounted around the outside of the mill. It was over 40 poles. Driven by a large cycloconverter. Wish I could remember the details better.
