Our company mainly producing and selling machines like jaw crusher, ball mill, sand maker, sand washing machine, mobile crushing mill girth gear radial Establishing a special research and development base and taking technological innovation as our main duty help us always taking the lead in the field of China mining machinery industry.
The girth gear is the main component of the rotary kiln and ball mill, which drives the entire cylinder to run for a long time. Therefore, in actual production, the quality requirement of the girth gear is the basis of rich manufacturing experience and advanced equipment, CHAENG is able to offer high quality girth gears according to users'' drawings and requirements.
#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.
Girth Gear Applications Girth gears fall into two basic categories; flange mounted and tangential spring mounted. Flangemounted 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.
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.
#0183;#32;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. In order to ensure their reliable operation, in addition to strengthening the daily maintenance and regular maintenance, the installation and alignment of the girth gear and pinion are also important.
The ball mill trunnion is a key part to support and connect the cylinder, and is also the inlet and outlet channel of the material. CHAENG adopts highstrength steel and unique heat treatment technology, which makes ball mill trunnion have high hardness and strong impact resistance.
Check where to position a dial gauge to measure radial runout of a Girth Gear, hope this helps, thanks for viewing :)

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
Gear cutting of a split girth gear for a cement mill having an input power of 2200 HP 5. Separate mill A: Damage to mill cylinder, neck or stub endanger girth gear and pinion. Repairs entail extra work for girth gear dismantling. B : Damage to mill cylinder cannot endanger gear teeth. Mill repairs do not entail gear dismantling. KAANU FAC TU RE 6.
A dial gauge E is placed at the midpoint of girth gear tooth width. The micrometer pointer is to be vertically measured to measure the radial runout of girth gear; a dial gauge A is placed on the end face of the girth gear to measure the end face runout of the girth gear; two dial gauges B and C are respectively placed at the shoulder of the ball mill trunnion and separated by 180#176;, to
We are engaged in manufacturing and supplying Girth Gear, Industrial Girth Gear, Kiln Girth Gears. This girth gear is widely demanded in different industries to be installed in different machines such as Rotary Kilns, Rotary Dryers and Ball Mills, girth gear for ball mill, girth gear for cement mill, girth gear for raw mill, girth gear for rod mill, gear for ball mill, gear for rod mill, gear
7 Radial runout of the girth gear measured in the field 8 Floating shaft movement measured in the field For the successful operation of industrial ball mills, the radial runout of the girth gear arising out of thermal and structural loads has to be monitored.
One side drive provides a power range up to approximately 8,000 kW when engaged with the girth gear of your ball mill. In dual arrangement, with one gear unit on either side of the mill, our MAAG#174; LGDX gear unit covers grinding applications up to 14,000 kW.
