Jaw crusher is commonly known as Epu, also known as Tiger Mouth. The crusher is composed of moving jaw and static jaw, which simulates the movement of animal's two jaws and completes material crushing operation. Widely used in mining, smelting, building materials, highways, railways, water conservancy and chemical industries, all kinds of ores and bulk materials of medium size crushing. The crushed material has a compressive strength of 320 Mpa. Next mobile gravel machine rental manufacturers to summarize the details of this kind of gravel machine operation should pay attention to!
1. Jaw crusher must start without load. If the crusher makes abnormal knocking sound after starting, it should stop running and restart the machine after identifying and eliminating the malpractice. After a certain period of time after starting, the feeding equipment can be operated normally. The ore fed into crusher should be gradually increased until full load operation, and overload should be avoided as far as possible.
2. In the course of operation, attention should be paid to whether the lubrication of each lubrication point is normal. Pay attention to the bearing temperature, especially the eccentric bearing temperature is not allowed to exceed 600C. Often check the wear condition of the ore discharge port, and adjust the size of the ore discharge port in time according to the wear condition.
3. In the course of operation, we should also pay attention to the large ore block jamming the feeding port of the crusher. If it has been jammed, we must use the iron hook to turn over the ore to remove it. If the ore is blocked in the crushing chamber, it should stop feeding until the ore in the chamber is crushed and opened to the miner. If the large ore needs to be removed from the crushing chamber, it must be stopped and treated with special tools. It is strictly forbidden to take the ore out of the crushing chamber by hand in order to avoid accidents.
4. In operation, attention must be paid to uniform ore feeding, and ore must not be crowded into the crushing chamber. At the same time, the shovel teeth and drill bits of the electric shovel should be strictly prevented from entering the crusher. Once it is found that these non-broken objects enter the crushing chamber and pass through the discharging port of the machine, the belt transportation post should be notified immediately to take them out in time so as not to enter the next crusher and cause serious equipment accidents.
