R=spherical roller trunnion bearing, discharge end K=ring gear and pinion drive CRRK is the common type in wet grinding. The PRRK-series is often used for dry grinding in rod mills, and in certain ball mill applications. Type CHRK is designed for primary autogenous grinding, where the large feed opening requires a hydrostatic trunnion shoe bearing.
OEM visual inspection of the mill with temperature, pressure, and flow readings. Catch cracks, drivetrain misalignment, oil contamination, vibrations, missing bolts, equipment condition and more. Performed with 1 shift with mill running and 1 shift with mill stopped. Historical data helps predict mill component performance over time.

Between the rod and ball mill an intermediate separator in the form of a hydrocyclone was placed. Determine power at the pinion shaft (including loss due to bearings, friction, etc.) for 1. wet rod mill grinding, 2. wet ball mill grinding. Data: Both mills filled to 35% of their internal volumes. Both mills operated at 70% of the critical speed.

The grinding process with one 34' x 20' SAG mill and two 24' x 39.5' ball mills will be briefly discussed. All three mills are gear driven by a ring gear, dual pinion and two low speed synchronous motors. Copper Mountain has installed on all three mills, the new state-of-the art dual pinion mill drives.
Along the shaft that connects the motor to the pinion gear are two bearings these are the INBOARD and the OUTBOARD pinion bearings, they may be one of two types a HYDRODYNAMIC, or a ROLLER BEARING.
The 38" Standard Hammermill has a screen area that ranges from 1,242 to 5,148 square inches, horsepower that ranges from 50 to 350 HP and tip speeds of 17,836 ft./min. Designed for the most demanding applications, the heavy-duty Champion Series Hammermill comes in a variety of sizes and models that match any particle size-reduction and grinding ...
A grinding mill assembly (50) includes a mill shell (10), a pair of mill bearings (54) supporting the mill, a motor (58) configured to drive said mill shell, and at least one of a noise sensor (68) and a vibration sensor (74). The at least one sensor generating an output signal indicative of whether a charge (12) within the mill shell has cascaded.
