The shovel blade picks up the material and send it between the grinding roller and grinding ring. The ball mill is a horizontal structure. When ball mill works, the rotation of grinding body drives the steel balls inside. The grinding media, steel balls, reach a high point and fall down. The compaction against each other grinds materials into ...
The cost of edge drive is low, but the pinion needs to be replaced every 25 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.
The ball mill understudy has a length of m in its cylindrical geometry and a length between supports of m (Fig. 1 a,b).The formation of cracks in the middle span has been identified, generally spreading from the holes near the maintenance manhole, as shown in Fig. 1 c. Certified welders carry the repairing procedure using PERMA 622 electrodes [1].
