Flange-mounted girth gears, the more common of the two, are most frequently utilized in “cold” processing equipment such as SAG (semi autogenous grinding) mills and ball mills for use in the mining and cement industries.

Girth Gear Inspection Pre and Post Manufacture

The girth gear driving pinion ends up getting aligned to the reduc-er, causing a misalignment issue between the girth gear teeth and the driving pinion teeth (Fig. 1). Proper alignment should consist of: axial and radial alignment of the girth gear to the center line of kiln/mill; center line of the driving pinion is aligned to the center lineBall Mill Maintenance & Installation Procedure,Metallurgical ContentBall Mill Maintenance ManualOn Mill Installation and MaintenanceBall Mill Concrete FoundationsGrinding Mill FOUNDATIONGROUTINGBall Mill Sole Plate Am sure your Ball Mill is considered the finest possible grinding mill available.

Ball Mill Critical Speed Mineral Processing & Metallurgy

A Ball Mill Critical Speed (actually ball, rod, AG or SAG) is the speed at which the centrifugal forces equal gravitational forces at the mill shell’s inside surface and no balls will fall from its position onto the shell. The imagery below helps explain what goes on inside a mill as speed varies. Use our online formula The mill speed is typically defined as the percent of the TheoreticalAn Elementary Guide to Gear Inspection Gear Solutions,Size measurement is used to provide the correct backlash when the gear is mounted with its mating gear at operating center distance.

Photo of the Week: Girth Gear Run-Out Procedure

Generally speaking, a girth gear that does not meet ideal measurements should be replaced, or other areas of the drum can be negatively affected. Replacing, as opposed to servicing the gear, is often the most economical choice. Girth gear run-out procedures should be done on newly installed drums, and during annual inspections.TECHNICAL How to Spec a Mill Gear Power & Transmission,the mill builder can provide the gear designer with input power and output speed. The next step is the interface dimen-sions. Since the gear needs to turn the mill, it needs to have a bore larger than the mill outside diameter.

As this is the key to accurate spindle run-out! Before you put your DB/Sl into service after purchase or storage, service the bearings. Keep in mind some of these units are 45 years old and grease hardens up. If your spindle bearing are noisy or worn and can not maintain run-out .0005",replace them!Ball mill Wikipedia,A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering.It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about its axis. TANSWERS TO COMMON MILLING PROBLEMS,Tool Run out Check tool run out in holder/spindle.
