The cost of edge drive is low, but the pinion needs to be replaced every 2-5 years. Edge drive is mainly used in coal mills and mills with small power. 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.

Dear friends, We have just finished to installation girth gear of ball mill. all measurement are good in cold conditions. but after ball mill worked, temperatures of mill and gear increased. and gaping of girth gear joints are opened a little bit. pitch errors between the two girth gear halves due to temperature. what can we do to solve this problem.

The ball mill design consists of a central vertical shaft driven by a motor -speed reducer set. The vertical shaft has a number of radial arms extending outward. At the end of each arm there is a pocket which holds one grinding ball. The ball rolling against the side of the vat grinds the chocolate and sugar to 30 micron size particles.

When an important gear failure occurs, someone becomes responsible for analyzing the failure, determining its cause and recommending a solution. A company can select its own engineer, an outside consultant or both. If a consultant is called in, this should be done as early in the process as possible. Though similar procedures apply to any failure analysis, the specific approach can …
