The discharge end of the mill For the operator this only becomes a problem should the bolts that hold the liners in begin to leak water and ground rock. This combination is called SLURRY.Torque limiting couplings in a ball mill Ball and SAG Mills In the grinding process, the dual pinion drives can sometimes come out of sync due to problems in the motor control system. Frozen or solidified minerals inside the mill might also cause torque peaks when tipping over.
Flexible drive solutions for use in ball mills A ball mill is a horizontal cylinder filled with steel balls or the like. This cylinder rotates around its axis and transmits the rotating effect to the balls. The material fed through the mill is crushed by the impact and ground as a result of the friction between the balls.WEG successfully tests dual-pinion ball mill drive WEG has successfully tested low speed synchronous motors driven by frequency inverters for mills with dual pinions at its plant in Brazil. As a multinational company, WEG supplies a range of solutions to the mining industry for driving large mills, including low and high speed motors, gearboxes.

In the chemical and process industries, grinding is an important step in preparing raw materials for subsequent treatment.
Single- or dual-motor configurations. In this type of application, the pinion to power is ~ mill diameter2.5. To get torque, we also need the speed of the drum. This is based on the concept of Ball mills are smaller still and use a larger percentage of balls to perform most of the work. Large-di-.Torque peaks, when there are synchronization problems or overloads caused by frozen charge during start-up. The dual pinion drives can come out of sync due to power problems or disturbances in the motor control system. Frozen charge inside the mill might cause torque peaks or consequential damage.
