Girth Gear Applications Girth gears fall into two basic categories; flange mounted and tangential spring mounted. 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.

The girth gear is also called gear ring or gear wheel, the major component used in rotary kiln and ball grinding mill which is required to be operated in a long time. So, the quality requirements during the actual production for the big gear ring are very high. We can custom and produce gear ring according to drawing and technical requirement。.

It is these characteristics in addition to flexibility in the machine's design that have made open gear drives the most common type of drive used for ball mills and grinding mills, kilns, dryers, draglines and shovels. There are two types of open gear drives; Type 1 utilizes a rack whereas Type 2 utilizes a gear or series of gears.

The Essa LM201 Pulverising Mill is a top-of-the-range vibratory mill suited to high-volume mineral laboratories regularly preparing samples in the unique Essa single-puck style of bowl. Flexibility. The user-friendly LM201 can be fitted with 800, 1000 or 2000 cc single disc-type grinding bowls, and the standard size ring-and-roller grinding bowls.

Many of the original Delco direct drive pinions do not engage the ring gear completely, causing the eventual grinding at 4 spots on the ring gear. This is primarily because when activated, the solenoid/bendix throws the already spinning pinion at the ring gear, hoping the ramped teeth will help feed the pinion into the ring.

When talking about ring geared mill drives (RMD's) and especially dual pinion systems (see figure 1), the possibility to add mechanical stress by the motors can be significant. Therefore the control concept between the two motors must be fast and accurate to avoid any additional stress to the pinions and the ring gear. Figure 1.
