Early attempts to provide load sharing on twin pinion drives used primitive electronics which have since been developed to eliminate the problems encountered in earlier attempts. In particular, torque pulsations between the twin motors have been overcome using a higher number of devices (pulses) and better electronics.
Ball/Sag/AG Mill, Roller Press HPGR/HRC The dual pinion drives in a mill can come out of sync due to power problems, or disturbances in the motor control system. Another common problem is frozen charge that has built up inside. This might cause torque peaks or consequential damage. Synchronization problems or jammed rollers in a roller press ...
The clutch's primary role on the dualpinion, directdrive geared mill is to provide smooth starts during mill startup. When the mill is running, the clutch also serves as a torque "circuit breaker," reducing costly repairs and downtime by protecting the pinions and ring gear from potential damage caused by large pieces of grinding material.

Parts of SAG Mill to be lubried: Trunion Bearing (feed end) Motor Bearings Gearbox Pinion Bearings : SAG mill Diagram Trunion Bearing (dis. end) 7. Lubricant Data: Masbate Gold Project's SAG mill uses Compounded Gear Oil as their main lubricant. But a different class of Gear oil is use in every operating system of the SAG mill.
Hi Observing high vibs on pressing and lifting pinion DE and NDE bearing on a ball mill. Motor and main GB drive are OK. Clear predominant gear mesh frequency is appearing in the spectrum along with harmonics and side bands. But 1st GMF is predominant. side bands with pinion speed is seen. no GG speed side band was observed Some of the vib data, spectrums and photos shown in the attachment.
been used. Singlepinion and dualpinion fixedspeed gear drives offer a relatively simple design. However, process flexibility and optimization can only be achieved with variable speed drives. Furthermore, mechanical problems and maintenance for gearboxes increase operating cost and reduce availability of ball and SAG mills.

20/03/2020 · Ball mill: When the particle size of the product is less than, the grinding effect of the ball mill is greater than that of a rod mill of the same specifiion. SAG mill: The SAG mill has a wide range of feeding particle sizes and can process larger minerals, but at the same time, its output particle size is relatively larger.
