SAG Mill Components | Stone Crusher
418· The document discusses the key components of SAG (semiautogenous grinding) mills, including mill heads, shells, trunnion bearings, and drives. Mill heads must carry the load of the shell, liners, and material while transmitting force evenly to trunnion bearings. Shell design requires stress and deflection analysis to determine appropriate thickness. Larger mills …

SINGLE AND DUAL PINION MILL DRIVES If we concentrate on the single and dual pinion configurations, we can see that these two configurations can be powered by low speed motors connected directly to the pinions driving the ring gear or by high speed motors that require a gear reducer between the pinions and the motors. Low speed motors are synchronous motors …

Smooth Operators
The clutch’s primary role on the dual-pinion, direct-drive 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.
