Ball Mill Motor Drive

In the past the conventional method of driving large ball mills included some form of speed reducing gear between the higher speed driving motor and the lower speed ball mill. Process developments in the mining and cement industries have increasingly tended toward the use of ever larger ball mills for grinding their products. As the horsepower drive ratings required have increased to several

Ball Mill Explained - saVRee

The motor is usually fitted with a variable speed drive (VSD) to control the rpm of the ball mill. Gearbox – used for speed reduction from the motor to the ball mill. Balls – usually manufactured from manganese alloy steel , but the material depends upon for what material the mill will grind ( chrome steel alloy and rubber also available).

Nov 26, 2019 The slow drive consists of a brake motor, a coupling, a planetary reducer and a claw-type clutch. The device is connected to a pinion shaft and is used for mill maintenance and replacement of liners. In addition, after the mill is shut down for a long time, the slow-speed transmission device before starting the main motor can eliminate the

The normal operation of the ball mill uses the motor to drive the ball mill to perform rotation operation. The motor drives the ball mill to directly connect the pinion through the elastic pin coupling and drive the big gear ring to realize the operation of the ball mill. In the process of

Electrolytic starter (LRS) for high power slipring motors

The level variation of electrolyte is pretty slow, which does not enable resistance to vary quickly enough for some specific applications (control of the slip for the ball mills for example). Why using a starter for slip ring motors. In order to start a slip ring motor, the accelerating torque has to be sufficiently higher than the resisting

One side drive provides a power range up to approximately 8,000 kW when engaged with the girth gear of your ball mill. In dual arrangement, with one gear unit on either side of the mill, our MAAG LGDX gear unit covers grinding applications up to 14,000 kW. Product features. Reliable gear unit components for a complete, adaptable side drive.

Ball mill special PM motor: In the traditional ball mill, the two most common transmission modes are : The 1st type: open peripheral gear transmission: that is, winding asynchronous motor drive reducer - reducer (or large winding synchronous motor) drive pinion- pinion meshing with gear ring mounted on the mill roller drive the mill.

•Additional vibration data was collected from the motor & gearbox of the 1A Ball Mill Drive under no load. •To determine what problems (if any) existed with the drive, a comparison of the route vibration data between 1A & 1B Ball Mills was made as well as between loaded & unloaded data at 1A Ball Mill.
