STEP 7. Bearing execution. STEP 8. Sealing, mounting and dismounting. Rolling bearings must be adequately lubricated to operate reliably. The lubricant is required to reduce friction, inhibit wear, protect the bearing surfaces against corrosion and may also be needed to provide cooling. This section describes: how to select between grease or oil.
11. 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. SAG Mill Components Type Characteristic Motor Bearings Omala 150 Gear oil. 150 viscosity at 40 C and 15 viscosity at 100˚C Gearbox Omala 320 Gear oil. 320 viscosity at 40˚C and 25 viscosity at 100˚C.
Before stopping the ball mill, stop the ore feeding first, after the ores are processed and discharged from the ball mill, can stop the ball mill motor and finally stop the lubrication system. With the help of the classifier's lifting device, lift the spiral out of the sand surface, and then stop the classifier.
