The working conditions of jaw crushers are quite bad, and incorrect operation or errors in operation often cause accidents. Practice has proved that strictly following the operating procedures of the equipment is important for the normal operation of the machine and improving the production capacity of the machine. The operating procedures of jaw crushers of different structures and specifications will be slightly different, but the basic principles are the same. The following describes the operation method of the medium-sized jaw crusher.
jaw crusher
    (1) After the crusher is started, a period of time will pass. In order to achieve the normal speed of the same rotation. When starting the motor, pay attention to the ammeter on the console, usually after 30~40s of starting peak current, it will drop to the normal working current value: during normal operation, also pay attention to the indicated value of the ammeter, and it is not allowed to ask for a long time. The specified rated current value, otherwise it is easy to cause accidents of burning the motor.
    (2) After the crusher is operating normally, the feeding equipment can be started to feed the crusher. When feeding the ore, adjust the feeding amount in time according to the size of the ore block and the working condition of the crusher, so that the feeding is even and avoiding overload. Generally, the height of the material in the crushing cavity should not exceed 2/3 of the height of the crushing cavity.
    (3) When the crusher is in operation, always pay attention to the phenomenon that large ore blocks are stuck to the mine gate. If it is stuck, turn it with an iron hook to remove it. If the ore is too much or the crushing cavity is blocked, the ore supply should be s ped, and the ore supply should be turned on after the ore block is broken. It is forbidden to take out ore blocks or sort ore by hand from the crushing cavity of the crusher. If there are large ore blocks that need to be taken out. It should be taken out with special equipment after parking.
    (4) Strictly prevent metal pieces such as shovel teeth, nuggets, drill bits, steel balls, etc. from entering the crusher. These non-crushed objects will damage the crusher. If any non-broken material enters the crusher and is passed again, the operator at the transportation post should be notified immediately to prevent entering the next process and causing an accident.
    (5) When the electrical equipment automatically trips, if the cause is unknown, it is strictly forbidden to start it continuously.
    (6) During the operation of the crusher, always check whether the lubrication of each lubrication point is good, and pay attention to the temperature of the bearing. The temperature of the eccentric bearing is not allowed to exceed 60 degrees. Check the oil temperature of the lubricating oil frequently, or check the temperature rise by touching the bearing by hand. If the oil temperature is out of the allowable range, or the machine makes an abnormal sound, s the machine immediately for inspection, find out the reason, and take corresponding measures. measure.
