With the expansion of the scale of cement production, the specifications of the rotary kiln are also increasing. As one of the important components of the rotary kiln, the diameter and weight of the girth gear increase accordingly (such as the girth gear produced by CHAENG for the φ4.8m×72m rotary kiln has a net weight of up to 32t), and the strength and rigidity of the girth gear become lower. During the operation of the rotary kiln, the girth gear often suffers from deformation problems.

 

The girth gear produced by CHAENG has high hardness, strong impact resistance, and strong anti-deforming capability.In view of the girth gear deformation problem that often occurs in cement plants, CHAENG has optimized the girth gear manufacturing process on the basis of summing up the traditional processing technology, improved process details, and greatly increased the life of the girth gear.

 

The traditional girth gear manufacturing process is: scribing → rough milling on half surface → combination → rough machining → fine milling on half surface → drilling reaming, combination → finishing → hobbing → disconnect → delivery.
