The spring cone crusher consists of a movable cone and a fixed cone to form a crushing chamber. The movable cone is pressed onto the main shaft (hard shaft), and one end of the main shaft is inserted into the conical hole of the eccentric sleeve. A bronze bushing or a nylon bushing is installed in the conical hole of the eccentric sleeve. When the transmission gear drives the eccentric sleeve to rotate, the main shaft deep inside the eccentric sleeve drives the movable cone to perform a swinging motion, so that the movable cone surface and the fixed cone are separated and combined from time to time, resulting in crushing and discharging of ore.

When the crusher is working, high-pressure oil enters the locking cylinder to raise the piston, slightly lift the locking nut and the adjustment ring, so that the serrated threads of the two are closely fitted in an inclined plane. When adjusting the discharge port, the locking cylinder needs to be depressurized to loosen the serrated thread, and then the hydraulic system is started to push the cylinder to move, thereby driving the adjustment ring to rotate left or right. With the help of the serrated thread transmission, the fixed cone is raised and lowered to achieve the purpose of adjusting the discharge port.
