When feeding the jaw crusher, it is required to observe whether the operation is good and there is no noise after half an hour of operation, and then perform the crushing work after normal. In addition, the initial feeding should be small-size crushed stone or all finished materials, so that the jaw crusher will not vibrate during the initial operation of the machine; the materials fed into the jaw crusher should gradually increase. Until fully loaded.

The particle size of the crushed materials must meet the requirements of the equipment, and the materials put into the crushing cavity must be the materials after screening. If it does not meet the requirements, a vibrating screen should be added to the front process of the jaw crusher, and the non-compliant materials will be returned and continue to be crushed. This will help increase the throughput and increase the productivity of the jaw crusher. The role of.

Because these materials that do not conform to the machine can fill the grooves between the edges of the jaws, the effective height of the edges is reduced, and the materials between the jaws are crushed only by pressure, so that the crushing force of the jaws on the materials is reduced, and the crushed materials The effect is not good.

Regular inspection of jaw crusher accessories: jaw crusher conveyor belt is indispensable in the stone production line. Regularly adjust the tightness of the conveyor belt to ensure that the conveyor belt is evenly stressed; the bearing wears relatively large in use, and often add lubricating oil to extend the use of the bearing life.

Do a good job in the lubrication of jaw crusher equipment components: timely lubrication of the friction surface can ensure the normal operation of the jaw crusher equipment and prolong its service life. The choice of grease should be determined according to the location of use, temperature and other conditions, and it should be replaced every three months; when changing the oil, clean gasoline or kerosene must be used to clean the dirt in the bearing and the bearing seat; the contact between the toggle plate and the toggle plate pad Before starting the machine, grease must be added.

What is the regular movement of a cone crusher? The counterweight is added to the large bevel gear of the cone crusher to eliminate the inertial force and moment of inertia caused by the direction change of the crushing cone. Due to the limitation of the size of the crusher, the inertial force of the crushing cone cannot be completely eliminated. Therefore, when the crushing cone rotates, a large unbalanced inertial force will be generated. This unbalanced inertial force causes the frame and foundation of the vertical shaft crusher. Disturbance of vibration.

That is, the disturbance force of the crusher is the unbalanced inertial force generated when the cone of the cone crusher rotates around the central axis. Vibration analysis under disturbance force. The vibration of cone crusher can be divided into free vibration and forced vibration according to the vibration reason. Because the body and foundation of the crusher are continuously excited by the outside, there will always be disturbance during the whole vibration process, so they are typical forced vibration. vibration.

According to the angular velocity vector diagram of the crushing cone of the cone crusher, due to the structural characteristics of the crushing cone supporting device, the crushing cone not only rotates with the eccentric hole of the eccentric shaft sleeve around the center line of the machine, but also rotates around its own axis. This kind of exercise is called regular exercise.

Since the center of mass of the crushing cone is not on the center of rotation, it will inevitably produce inertia force and moment of inertia during operation. This force acts on the frame as a periodic dynamic load, causing vibration of the frame and deflection of the eccentric shaft sleeve. When the cone crusher is in regular motion, it will produce periodically changing reaction force to the frame sleeve and spherical bearing when it is unloaded, which will cause harmful vibration of the frame and the eccentric shaft sleeve deflection and cannot work normally.

Cone crusher is a relatively large and important beneficiation equipment. During its operation, the wear of parts will seriously affect the stability of the vibration of the crusher. At the same time, the machine will be in a state of forced vibration for a long time, which will seriously affect the crusher. Safe operation. Pay attention to the maintenance of the crusher in use.
