#0183;#32;Re: Ball Mill Girth Gear and Pinion Alignment 08/27/2011 2:07 AM pinion alighnment is done by coating the pinion with a lead based grease. after rotating the drum, the grease marks will show the contact area. the pinion should contact the girth quot;ringquot; near the center of the gears.
Mill Girth Gears comprise high integrity girth gears that find application in driving horizontal grinding mills. With these gears developed for achieving superior finish strength and process reliability, these can be designed for different kW applications as well as in diameter and weight choices.

The girth gear driving pinion ends up getting aligned to the reducer, 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 line

The large girth gear of the ball mill not only has a large shape, but also has a certain weight. It is formed by combining two halftoothed gears, which is mainly for the convenience of disassembly and installation. The number of teeth of the large ring gear is generally even, and it needs to be opened on the tooth groove.
Keywords: Ball mills, grinding circuit, process control. I. Introduction Grinding in ball mills is an important technological process applied to reduce the size of particles which may have different nature and a wide diversity of physical, mechanical and chemical characteristics. Typical examples are the various ores, minerals, limestone, etc.
mills and ball mills for use in the mining and cement industries. By current standards, girth gears can be as large as 14 meters (46 feet) in diameter, 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 the mill structure to provide the stiffness

CHAENG has many years of experience in processing large girth gears for cement ball mills and limestone ball mills. In order to extend the service life of ball mill girth gears, CHAENG has studied a detailed processing plan, and every detail requires perfection to ensure the quality of cast steel girth following are suggestions for the processing of large cast steel gears by CHAENG:
installation procedure of girth gear of kiln. Ball Mill. Ball mills are used primary for single stage fine grinding, regrinding, and as the second stage in two stage grinding circuits. According to the need of customers, ball mill can be either wet or dry designs.
The girth gear is the main component of the rotary kiln and the ball mill. It needs to drive the entire Cylinder to run. Therefore, in actual production, the quality requirements of the girth gear are very high. CHAENG can process and produce various types of girth gear according to the drawings and dimensions provided.
