1. Moving jaw plate and fixed jaw plate:
• The jaw plate is the main working part of the jaw crusher and bears huge impact loads. During the crushing process, the edges of the moving jaw plate and the fixed jaw plate will be severely worn, and the wear is mostly concentrated in the middle and lower parts. This is due to the repeated impact and friction of the material during the crushing process.
• In order to extend its service life, the moving jaw plate and the fixed jaw plate are generally made of materials with good hardness and wear resistance such as high manganese steel. The replacement cycle of the moving jaw plate and the fixed jaw plate is generally from a few months to half a year, depending on factors such as the use conditions, the hardness of the stone, and the equipment load.
2. Side guard plate:
• The side guard plate is located on the left and right inner sides of the jaw crusher frame to protect the body of the jaw crusher. Under the impact of the material, the side guard plate will wear. When the wear of the side guard plate reaches a certain extent, a new side guard plate needs to be replaced.
• The replacement cycle of the side guard plate is generally long, usually about half a year, depending on the use conditions and the working intensity of the crusher.
3. Toggle plate:
• The toggle plate is an important component connecting the movable and fixed jaw plates, and is also a safety part of the crusher. When the crusher falls into materials that cannot be crushed and the machine exceeds the normal load, the toggle plate will break immediately and the crusher will stop working, thus avoiding damage to the entire machine.
• The toggle plate needs to be checked and replaced regularly, and its replacement cycle is usually about half a year. The toggle plate and the toggle plate pad adopt a sliding contact method, and there is little friction under normal use. Usually, a layer of grease can be applied on the contact surface.
4. Spring pull rod and spring components:
• As an important component in the jaw crusher, the spring pull rod mainly plays the role of connecting the adjustment seat and the rear support plate. At the same time, it can also adjust the size of the discharge port and maintain the stability of the jaw plate. The spring component and the spring pull rod are matched, and their main function is to fix the toggle plate, prevent the toggle plate from falling off, and absorb and buffer the vibration and impact during the crushing process.
• The replacement cycle of spring pull rods and spring components is generally about half a year, and the specific replacement cycle depends on factors such as usage conditions, working intensity, and maintenance.
5. Bearings:
• The jaw crusher bearings use multiple sets of spherical roller bearings, which have good load-bearing and self-aligning performance. The bearings mainly bear the radial load when the equipment is working.
• In order to increase the service life of the bearings, bearing materials with higher durability and load-bearing capacity can be used. The replacement cycle of the bearings is generally more than one year, depending on the bearing quality, usage conditions, and maintenance.
