Aggregate and Mining
Gyratory Crushers Gyratory crushers are similar in shape and operation to cone crushers. However, their moving crushing components gyrate (, oscillate along a circular path) rather than rotate. The crushing head can be heightadjusted, and the hole at the bottom of the crushing chamber determines the final size of the crushed material.

Troubleshooting Tips for Hydraulic Pumps
At temperatures of 200°F and higher, rubber seals have a very short life. Abrasives in the oil may wear seals out quickly, and will also produce circumferential scoring of the shaft in the seal area. If abrasives are present, they will settle out of a sample drawn from the reservoir if it is allowed to stand an hour or so. Check all points ...
