In order to ensure the continuous normal operation of large feeder breaker coal mining and give full play to the production capacity of the equipment, the operator must attach importance to the correct operation, regular maintenance and regular overhaul of the crusher from the ideological perspective. Correct use of large feeder breaker coal mining is one of the important factors to ensure the continuous normal operation of the crusher. Improper operation or negligence during operation is often the main cause of equipment and personal accidents. The correct operation is strictly in accordance with the provisions of the operation procedures. Before starting the feeder breaker coal minin, a thorough and careful inspection of the equipment must be carried out: check the wear condition of the crushing tooth plate, adjust the size of the discharge port: check whether there is ore in the crushing chamber, if there is a large ore, it must be removed: whether the connecting bolt is loose: Belt wheel and flywheel protection cover is complete: triangle belt and rod spring tightness is appropriate: storage tank (or thousand oil storage pump) oil filling degree and lubrication system intact condition: electrical equipment and signal system is normal, etc. Notes in use of large feeder breaker coal mining: Before starting the crusher, the oil pump motor and cooling system should be started first, after 3 to 4 minutes, when the oil pressure and oil flow indicator is normal, then start the motor of the crusher. After starting, if the crusher sends out abnormal knocking sound, should stop operation, identify and eliminate the disease, restart the machine. The crusher must be started idling, after a period of time, normal operation can be started to feed the ore equipment. The ore fed to the crusher should be gradually increased until full load is run.
Care must be taken to feed ore evenly in operation, and the ore should not be crowded with broken ores: and the maximum size of the feed block should not be greater than 0.85 times the width of the feed port. At the same time, the shovel teeth of the electric shovel and the drill bit of the drill are strictly prevented from entering the crusher. First, when these non-crushing objects are found to enter the crushing chamber and pass through the discharge port of the machine, the belt transportation post should be notified immediately to take them out in time, so as to avoid entering the next section of the crusher and causing serious equipment accidents. During the operation process, it is also necessary to pay attention to the feed port of the crusher when the large ore block is stuck. If it is stuck, it is necessary to use the iron hook to turn the ore: if the large ore needs to be removed from the crushing chamber, special instruments should be used. It is strictly prohibited to carry out these works by hand to avoid accidents. During operation, if there are too many feeders or the breaker coal mining chamber is blocked, the feeders should be suspended. After the ore in the crushing chamber is broken to play, the feeding machine is started again, but the crusher is not allowed to stop running at this time. In the operation of the machine, regular tour inspection should be taken to observe the working condition of each part of the crusher and bearing temperature by looking, listening, touching and other force methods. For sliding bearings of large feeder breaker coal mining, more attention should be paid to the bearing temperature, usually bearing temperature should not exceed 60℃, in order to prevent the melting of the bearing bearing containing gold, resulting in tile burning accident. When the bearing temperature is found to be very high, do not stop operation immediately, should take effective measures to reduce the bearing temperature in time, such as: increase the amount of oil, forced ventilation or water cooling, until the bearing temperature drops, can stop, check and troubleshoot, in order to ensure the normal operation of wet coal crusher is not allowed to unfamiliar with the operation of the operation of the crusher alone. When stopping the machine, it must be stopped in accordance with the sequence of the production process. First of all, the ore feeding must be stopped. After all the ore in the crushing chamber is discharged, the crusher and the belt conveyor can be stopped. When the crusher stops, the motor of the oil pump can be stopped. It should be noted that the crusher stops suddenly for some reason. When the accident is handled and ready to start, the backlog of ore in the crushing chamber must be cleared before operation. Maintenance and overhaul of large feeder breaker coal mining. In the operation of feeder breaker coal mining, attention must be paid to frequent maintenance and regular overhaul. In the crushing workshop, the working conditions of feeder breaker coal mining are very bad, and the wear problem of equipment is inevitable. But it should be seen that the too fast wear and even fracture of machine parts are often caused by incorrect operation and poor maintenance. For example, poor lubrication will accelerate the rapid wear of bearings. Therefore, correct operation and careful maintenance (regular overhaul) is an important way to extend the service life of the machine and improve the operation rate of the equipment. In daily maintenance work, for the correct judgment of equipment failure, accurate analysis of the cause, so as to quickly take the elimination method, which is the skilled operator should understand and master.
Feeder breaker coal mining can often be kept in good condition, in addition to correct operation, by maintenance, a repair (repair), and the maintenance of equipment is the basis of equipment repair. As long as we do regular maintenance, regular inspection and master the wear cycle of equipment parts in use, we can find out the defects of equipment parts as early as possible, and repair and replace them in time, so that the equipment will not reach the serious point of being unable to be repaired and scrapped. Therefore, the timely repair of equipment is an important link to ensure normal production. Working under certain conditions of equipment parts, the wear situation is usually enough to have a certain rule, after the work Ding time, it needs to be repaired or replaced, this time interval is called the wear cycle of parts, or the service life of parts. General situation of service life and minimum reserve of main easy wear parts of crusher
