LUBRICANT FEED FOR ROTARY CRUSHER

摘要

A gyratory crusher provided with a wobbling crusher cone supported by a dish-shaped sliding bearing on the upper end of an axially slidable piston arranged in a stationary tubular shaft and provided at the lower end of the piston with a pressure medium chamber for adjusting the piston slidably in said tubular shaft is provided with a lubricant system comprising a lubricating channel extending centrally along the axis of the entire piston and connected with its upper end with the center of said sliding bearing, while the lower end of said lubricating channel slidably engages a tubular pin which extends through said pressure medium chamber and is fixedly attached to a cover plate which closes the lower end of said tubular shaft. An exterior lubricant supply source is connected with the lower end of said tubular pin which extends through said cover plate.
