4.) Draw a construction line ( 1, 2 ) from the center of the circle through the top quadrant. Where this line intersects the circle is the location of point a. 5.) Draw a horizontal line ( 3, 4 ) through point a, (the top quadrant,) of the pitch circle. Make this line tangent to the pitch circle. 6.) Draw a circle with radius = R

GROSS POWER CALCULATOR - SMC Testing

the so-called "power at pinion", which is slightly lower than the gross power and relates to the power as measured at the shaft which drives the pinion gear in a gear-and-pinion drive. Apart from in pilot-scale ... power draw of an AG/SAG mill to drop can be gauged by switching the discharge mechanism choice in

Ball Mill Maintenance & Installation Procedure

Establish vertical and horizontal centerline of mill and pinion shaft against the effects of this, we recommend that the trunnion bearing sole plate be crowned so as to be higher at the center line of the mill. This is done by using a higher shim at the center than at the ends and tightening the foundation bolts of both ends. Ball Mill Sole Plate

Sugar Mill Pinions

While the tooth profile of a mill pinion is an involute curve, this fact is not helpful to th pattern maker in the foundry where the pinion will be cast. The involute curve is approximated by two arcs: one from the base circle to the pitch circle, the second arc extends from the pitch circle to the start of the tip radius of the tooth.

How to install and align the girth gear and pinion | prmdrive

The cost of edge drive is low, but the pinion needs to be replaced every 2-5 years. Edge drive is mainly used in coal mills and mills with small power. The girth gear(big ring gear) and pinion are the key of the edge transmission device. Their reliable operation is directly related to the stable production of the mill.

Rod Mill Design & Power Draw - Mineral Processing & Metallurgy

The rod mill motor power is in horsepower at the mill pinion-shaft. For different length rod mills power varies directly as rod length. For difference between new and worn liners increase power draw by 6%, and adjust for bulk density per Table A. Wet grinding rod mills are normally used in minerals processing plants.

Mill drives: the desire for increased power and the ...

design mill speed, and the maximum design ball charge volume (Barratt, 1989). For single pinion and dual pinion drives, with 21 MW now a distinct possibility, the probability of pinion changes to a higher mill speed should always be considered when set-ting gear ratios, service factors, and motor power ratings.

Rod Mill Design & Power Draw - Mineral Processing & …

The power draw of the mill is then obtained by multiplying KWr by the tons of rods in the mill, which yields: KW = (πD²/4 L V pρ) (1.07 D.34 (6.3-5.4 Vp ))Cs…………………………………………………. (3) KW = mill power draw at the pinion shaft, kilowatts. p = rod charge bulk density, tons per cubic foot. L = mill effective working length, feet.
