Clearing jack for cone crushers

摘要

A clearing system for a cone crusher used to crush rock. The clearing system includes an actuating member which engages and lifts a lower push rod which is guided through a lower rod boss so as to remain axially aligned with an upper push rod, which in turn is guided by an upper rod boss. The upper push rod engages an adjustment ring which allows the crushing chamber sections to be separated to allow clearing of foreign material from the crusher. A preferably removable intermediate guide engages the lower push rod between the lower rod boss and the actuating member so that the lower push rod remains axially aligned with the actuating member and the upper push rod.
