The Problems and Improvement of Jaw Crusher

Aug 18 2014

Jaw crusher is widely used for crushing stone in many production lines because of its big processing capacity. However, there are many problems in practical application. This article will discuss the problems and improvement of jaw crusher.


In the crushing process, jaw crusher crushes materials by the power passed from the triangle belt. But if the adapter sleeve of jaw crusher’s eccentric shaft is loose, the eccentric shaft will be deadly stuck, and the jaw crusher will be forced to stop. Besides, in the production, if materials are discharged slowly, or there is material blocking phenomenon at the discharge port, these phenomena will affect the normal work of the whole production line.


Since when the thread is right-handed, the seal cartridge will move to the end of the pulley, but the taper sleeve of the pulley will not loose. So the threaded direction of the pulley needs not to change. So we should change the threaded direction of the seal cartridge and the sleeve from right-handed to the left-handed. Then when the eccentric shaft rotates counterclockwise, the sealing sleeve will move to the flywheel and push the flywheel to fix on the eccentric shaft because of the inertial force. Then the taper sleeve can be fixed on the eccentric shaft tightly, reducing the downtime of the equipment.
