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.

Our PowerFlex#174; 7000 Medium Voltage AC Drives are aircooled or liquidcooled drives available in a broad power range of Hp and supply voltages of V AC. These general purpose, standalone drives control speed, torque, direction, starting, and stopping of standard asynchronous or synchronous AC motors.
AC drive is also known as VFD (variable frequency drive), VSD (variable speed drive) or ASD (Adjustable speed drive). The different types of AC drives operate on the same principle they convert the fixed amount of input voltage and frequency into the variable voltage and frequency output to control the motion of AC motors.
Our GMD eliminates all mechanical components of a conventional mill drive system, such as ringgear, 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.
Use a Treadmill DC Drive Motor and PWM Speed Controller for Powering Tools: Power tools such as Metal cutting mills and lathes, Drill presses, bandsaws, sanders and more may require .5HP to 2HP motors with the ability to fine tune the speed while maintaining most Treadmills use a 80260 VDC motor with
(AC induction motors need varying frequency to control their speed.) The 1 hp single phase motor would be a good candidate for a belt grinder. Preferably it is sealed (TEFC) and has a suitable shaft 5/8quot; or 7/8quot; diameter for mounting a wheel.

Dual pinion highspeed mill drive (with gearbox) and dualpinion lowspeed mill drive (without gearbox). By using the latest generation medium voltage frequency converter drives of ABB as shown in figure 2, with exclusive DTC (direct torque control) technology,
efficiency of grinding mills is low. Optimizing the grinder speed by using AC drives ensures efficient use of energy and an improvement in the overall efficiency of the grinding process. ABB drives can be used to control the speed of permanent magnet motors in applications running at low speeds. This
Common types of grinding mills include Ball Mills and Rod Mills. This includes all rotating mills with heavy grinding media loads. This article focuses on ball and rod mills excluding SAG and AG mills. Although their concepts are very similar, they are not discussed here. Photographs of a glass ended laboratory ball mill show action of ball mass within the mill. The action of other grinding
A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.
