Large diameter casting steel ring gear for ball mill/rotary kiln

Large diameter casting steel ring gear for ball mill/rotary kiln

    The girth gear is the main component of 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.

 1) The particular heat treatment technology is used for the big gear ring manufactured by Tongli Machinery which makes the improvement in the structure optimization and the hardness of the product. The performance of wear-resistant and anti-impacting are also enhanced greatly.

2) The high strength steel was used by us in manufacturing the big gear ring. We also take the optimization for the product against the operation characteristics of the rotary kiln to ensure the stability of the component during the long time operation and extend the service life of the component.

3) Our company has rich production capability in steel castings. For the components such as the girth gear ring, we can provide them in large production quantity with short cast period and large amount.
