In order to ensure the normal operation of jaw crusher and give full play to the production capacity of the equipment, it is necessary to pay attention to the correct operation, regular maintenance and regular overhaul of the crusher. In particular, correct use is one of the important factors to ensure the continuous normal operation of jaw crusher. Improper operation or negligence during operation is often an important cause of equipment and personal accidents. Correct operation is strictly in accordance with the provisions of the operation procedures.
Precautions in the use of jaw crusher:
1. Before starting the crusher, the motor of the oil pump and the cooling system should be started first. After 3-4 adding minutes, the motor of the crusher should be started when the oil pressure and oil flow indicator is normal.
2, after starting, if the crusher makes an abnormal knocking sound, it should stop the operation, identify and eliminate the defects, and restart the machine.
3. The crusher must be started without load. After starting, it can run normally before starting the ore feeding equipment. Ore for crusher should be gradually increased until full load operation.
4, the operation must pay attention to uniform ore feeding, ore is not allowed to fill the crushing chamber: and the maximum size of the ore block should not be greater than 0.85 times the width of the feeding mouth. At the same time, when feeding the ore, strictly prevent the shovel teeth and drill bits and other non-broken objects into the crusher. Once these non-broken objects are found to enter the crushing chamber and pass through the mine outlet of the machine, they should immediately notify the belt transport post to take them out in time, so as not to enter the next section of the crusher and cause serious equipment accidents.
5, in the process of operation, but also often pay attention to the large ore block stuck crusher mouth, if it has been stuck, must use iron hook to turn over the ore; If large ore needs to be taken out from the crushing chamber, special instruments should be used. It is strictly forbidden to carry out these work by hand, so as to avoid accidents.
6. In operation, if the ore is too much or the crushing chamber is blocked, the ore feeding should be suspended. After the ore is crushed in the crushing chamber, the feeder can be started again, but the crusher is not allowed to stop running at this time.
7. In the operation of the machine, regular inspection should be taken to observe the working condition and bearing temperature of all parts of the crusher by means of seeing, listening and mould. For large jaw crusher sliding bearings, more attention should be paid to the bearing temperature, usually bearing temperature shall not exceed 60℃, in order to prevent the melting of alloy sleeve, burning tile accident. When it is found that the bearing temperature is very high, do not stop running immediately. Effective measures should be taken to reduce the bearing temperature in time, such as increasing the amount of oil, forced ventilation or water cooling. After the bearing temperature drops, it can be stopped. Check and troubleshoot.
8. When the crusher is stopped, it must be stopped in accordance with the production process sequence. First of all, we must stop feeding. After all the ore in the crushing chamber is discharged, we must stop the crusher and belt machine. When the crusher stops, the motor of the oil pump can be stopped.
9. It should be noted that the crusher stops suddenly for some reason. Before the accident is handled and ready to start, the backlog of ore in the crushing chamber must be cleared, and the operation shall be allowed.
10. In order to ensure the normal operation of the machine, it is not allowed to operate the crusher alone without being familiar with the operation procedures.
