Advantage of central drive system ball mill : central drive ball mill - dent-all. Center drive ball mill. The central drive ball mill adopts gear reducer which has large transmission ratio compact structure stable operation low noise and easy maintenance The transmission efficiency can reach 96 which is 73 higher than that of conventional mill transmission and
Apr 03 2013 The mill derives its name from the unique kinematics wherein the grinding bowls are mounted on a rotating sun disk that rotate in the opposite direction around the disk centre. Because of this the samples are quickly and effectively comminuted by impact frictional and shear forces resulting from ball-to-wall and ball-to-ball collisions.
Ball mills are known worldwide as straightforward and a reliable comminution system used in cement and mining application. Two fundamentally different philosophies exist to drive horizonal mills: While the gear unit and the electric motor of a central drive are located at the front of the mill and take up a lot of space the lateral drive is ...

Jun 17 2020 Two fundamentally different philosophies exist to drive horizonal mills: While the gear unit and the electric motor of a central drive are located at the front of the mill and take up a lot of space the lateral drive is placed at the side of the mill. The three-stage spur gear unit includes a mechanical torque split and contributes significantly to the extremely compact setup.

Outotec offers a full range of ball mills to suit a wide variety of duties from a few hundred kW all the way up to 20 MW and beyond. Rod mills
The Ball-Mill Drive System Looking inside the mill's motor compartment you can now see the motor with a small fan and pulley on its shaft. That small pulley is connected by a drive belt to a large pulley which is mounted on the unit's drive roller. The other roller is the idler roller which simply rolls along with the mill jar when the drive ...
The new drive systems are replacing the existing synchronous motors and direct converters for the SAG mills and the drive systems of the ball mills which were installed by a different manufacturer. The standardized system design now offers all the benefits of controllable drives also for the ball mills.
The speed control system behaves like a DC machine. The TRANSVEKTOR control system used on high-power mill drives has gone through a long development phase. A lot of experience has been gained with this system during the last 33 years. The first gearless drive with this control has been operating successfully for more than 30 years.
