Gyratory Crusher Lube System

How a Gyratory Crusher Lube System Works: Certain components in the crusher (pinion shaft and bearings, pinion and eccentric gears, eccentric bushing, and step bearing) require continuous oil lubrication. http://www.911metallurgist.com/blog/g... The lubrication system is comprised of an oil reservoir, pumps, heat exchanger, and protective instrumentation. Its function is to lubricate and cool the crusher moving parts and keep them clean. • The spider bearing is lubricated with grease. The grease is drawn from a grease barrel and injected into the bearing at preset intervals by a timer circuit. • The hydroset system is used to change the gap between the mantle and concaves by raising or lowering the mainshaft assembly and mantle from underneath. • Sometimes very large rocks or items of tramp steel enter the crushing chamber. In a gyratory crusher these can cause the mainshaft to move suddenly upward in a jumping action. When this occurs a balance cylinder in the oil line maintains hydraulic support under the mainshaft. This prevents it from dropping suddenly, and damaging the crusher, when the condition is relieved.
