Girth Gears More than Just Metal and Teeth Gear
such as SAG (semi autogenous grinding) mills and ball mills for use in the mining and cement industries. By current stan-dards, girth gears can be as large as 14 meters (46 feet) in diameter, 1.1 meters (44 inches) face width, and 50 module (.5 DP) tooth size, and weighing upwards of 120 tons. Flange mounted gears rely, in large part, on theThe 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 lineGirth Gear Inspection Pre and Post Manufacture

Unlocking the Secrets of Mill Pinion Gears
As the motor rotates, the pinion gear engages with the mill’s girth gear, efficiently transferring power to the mill’s drum or shell. This power transmission is essential for the mill’s operation and the grinding of materials. Torque Distribution. Even torque distribution is a key function of mill pinion gears.It is highly acknowledged for effective and quick grinding in several industries such as limestone, cement, coal, iron ore, chrome ore and many others. The major highlight in the mill is its fully automatic function with PLC control and instrumentation. We are manufacturer and supplier of ball mills since 1980. 400 installations worldwide withClosed and Open Circuits Ball Mill for Cement, Limestone,

Ball Mill Maintenance & Installation Procedure 911
Ball Mill GEAR GUARD. A plate steel gear guard is furnished with the mill for safety in operation and to protect the gear and pinion from dirt or grit. As soon as the gear and pinion have been cleaned and coated with the proper lubricant, the gear guard should be assembled and set on its foundation. DISCHARGE HOUSING “Doghouse”b) Clean and crack detect gear using magnetic particle method. c) Install Hofmann case hardened Pinion.

Development of High-Hardness-Cast Gears for High
The second parameter manufacturers have worked on is gear size: the more teeth, the larger power, but also larger is the diam eter and the mill a gear can be assembled on. As previously said, a 36' SAG mill was the limit a mill can be equipped with a mechanical drive, simply because the largest gear cutting machines were about 14 m/46' Extensive experience in delivering large, multi-segment, cast and fabricated girth gears for pyro processing and grinding applications. Application-based design techniques ensure each segment is matched to our customers’ specifications, delivering optimal and reliable performance. Our girth gears are machined to exacting tolerances.Cement Industry Gear design & Manufacturer David Brown
