The pinion is a part of rotary kiln, girth gear and pinion transmit the motion and the dynamic force according to the required speed ratio. pinion gear is also known as kiln pinion and is widely applied in many equipment, take cement equipment as an example, rotary kiln and ball mill are two typical applications.

As one of the small spare parts of a rotary kiln, the kiln pinion must be repaired regularly, For example, sometimes there will always be some abnormal sounds during rotary kiln operation, then it is very likely that the pinion is loose, so it is necessary to repair or replace the pinion in time.

What do we offer?

  • we specialize in providing various types and specifications of girth gears and pinions. It can process gear rings with a diameter of 6 meters and a module of 32 modules. At the same time, various non-standard transmission machinery products can be supplied according to user requirements and drawings. The material used is of good quality and the machining accuracy is high.
  • Professionally provide all kinds of spur gears, helical gears, sprockets, and various large gears, worms, turbines, ring gears, aperture eccentric shafts, etc.; non-standard and special types of ring gears can also be customized. (processing module 2.5 – 32M, processing diameter 0.1 – 6.3 meters), can be used in tumble dryers, ball mills, rotary kilns, coolers, cement equipment, and other large gear transmission machinery.
  • In addition, it can be customized according to drawings, samples, and materials. For customers who want to customize gears pinion, please send drawings or report the size to customer service to calculate the price for you.
