Gyratory crusher lubrication and filtration - Crushing ...

2021-8-29  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. Use the Social Share Bar on the Left.
