Jaw crusher, also known as jaw breaker or jaw breakers, fulfills the crushing process by simulating the movement of the two jaws of an animal. Jaw crusher machine is mainly used for primarily crushing the raw materials, so that is also called primary jaw crusher or primary crushers. Small jaw crusher or mini jaw crusher, as new type crusher equipment, is widely used in all kinds of ores and large materials’ medium size crushing in mining, smelting, building material, highway, railway, water conservancy, chemical industry, etc.
The crushed material’s maximum compressive strength is 320 mpa. In the process of crushing operation, in addition to the pursuit of high yield and high efficiency, more attention should be paid to small jaw crusher’s operation details at the same time. The following are some attention points:
1, no-load start: after starting small jaw crusher, if there is abnormal tapping, operators should stop machine to identify and eliminate evils, and then reboot the machine. After starting a certain time, the functioning is normal, and operators can start the feed equipment.
2, pay attention to lubrication and temperature: in the process of running, operators often should pay attention to whether lubrication is normal in all lubricating points. Pay attention to the temperature of the bearing, especially the temperature of the eccentric shaft bearings is not allowed to exceed 600 ℃.
3, feeding mouth blockage problem: during operation, operators also should pay attention to whether the big ore blocks stuck crusher’s feed mouth, if stuck, operators can use the hook to flip ore and make it out.
4, pay attention to even feeding: in the operation, the ore is not allowed to fill full of crushing cavity, and prevent excavator, drill bit and other non-crushed materials coming into the crusher.
