Details of the jaw crusher operation

Commonly known jaw crusher broken jaw, the movable jaw and static jaw crushing chamber consisting of two jaws, the jaws moving simulated animal completed the material crusher crushing operations. Widely used in mining, smelting, building material, highway, railway, water conservancy and chemical industry in a variety of ores and bulk materials of medium-grained broken. The highest compressive strength of the crushed material is 320 MPa.

Jaw crusher operation details

The structure of jaw crusher mainly consists of frame, eccentric shaft, large pulley, flywheel, moving jaw, side guard, bracket, bracket rear seat, gap screw, return spring, fixed jaw and flow jaw. The brackets also serve as insurance. So what details should be paid attention to during operation? The following is a detailed introduction for everyone:

1. The jaw crusher must be started at no load. If the crusher makes an abnormal knocking sound after starting, stop running, identify and eliminate the ills, and restart the machine. After a certain period of time after starting, the operation can be normal to start the mining equipment . The ore fed into the crusher should be gradually increased until it is fully loaded, and overload should be avoided as much as possible. Article link: Global Crusher Network http://

2. During operation, always pay attention to whether the lubrication of each lubrication point is normal. Note that the temperature of the bearing, especially the temperature of the eccentric bearing, must not exceed 600 °C. Frequently check the wear and tear of the discharge port, and adjust the size of the discharge port in time according to the wear situation.

3. During the operation, always pay attention to the large ore block stuck to the feeding port of the crusher. If it is stuck, it is necessary to use the iron hook to turn the ore to remove it. If the ore blocks the crushing chamber, the ore should be stopped. When the ore in the chamber is broken, the ore is opened. If the ore needs to be taken out of the crushing chamber, it must be shut down and then treated with special tools. It is strictly forbidden to use the hand to remove the crushing chamber. Remove the ore to avoid an accident.

4. It is necessary to pay attention to uniform ore feeding during operation, and the ore is not allowed to be filled with crushing chambers. At the same time, the non-crushing materials such as the shovel teeth and the drill bit of the electric shovel are strictly prevented from entering the crusher. Once these non-broken objects are found into the crushing chamber and pass through the discharge port of the machine, the belt transport post should be immediately promptly taken out to avoid entering the next section of the crusher, causing serious equipment accidents.
