Complete safety procedures for jaw crushers
Start operation methodComplete the above inspection and preparation before you start.1 start the lubrication system and start the ventilation and water supply system at the same time.2, according to the technological process, start the crushing system, the lower ore handling system.3 、 no-load start jaw crusher.4, after the normal operation, start the ore feeding system.5. Start up.6. Fragmentation crusher with sectional starting device is started according to crusher starting program.
Preparation and inspection before operation1, crusher start, you must first start the thin oil lubrication system, as the oil back to normal before starting.2, operation manual dry oil, make each lubricating point sufficient gas.3, the manual dry screw oil cup.4, to the oil at the same time, check the oil system has no blockage, oil leakage phenomenon.5, check all kinds of instruments are normal.6. Check whether there is any ore or other non broken substance in the crushing chamber.7, check the electrical interlocking devices, lighting signals and protective facilities are complete and effective.
Rational use of crusher1, crusher feeding specifications shall not exceed the size of the mine mouth 0.85 times.2 jaw crusher must start without load.3, jaw crusher is suitable for crushing hard, medium and hard ore coarse breaking and crushing.
Stop operation and emergency shutdown1, crusher stop, must be all discharged ore, before you can stop.2. When stopping, the ore body should be stopped first.3 、 the main engine is shut down for 5 minutes, then the oil pump and cooling water system can be stopped.4, the following situations should be emergency shutdown:(1) the main bearing or moving jaw bearing rises sharply over 80C degrees. The surface phenomenon is that the back of the hand can not touch the bearing seat for one second.(2) rupture of front or rear thrust plate.(3) the high speed rotating parts are loose or broken and may fly out of the human body.(4) the machine smokes and sweeps the air.5 emergency shutdown should meet the following requirements:(1) not stopping immediately because of the high temperature of the bearing.(2) high temperature shutdown should first stop to the mine, increase the amount of oil, forced air cooling or water cooling, until the bearing temperature drop, you can stop.Five, safety precautions1, the operation often monitors all kinds of instrument is normal, each component has abnormal sound.2, crusher hydraulic chain system, under any circumstances can not be removed.3, the machine running, in the jaw crusher rotation surface shall not stick.4, the operator may not use hand to access the machine into the large ore or other items.5, treatment of jaw crusher ore blocking, should first get rid of the ore feeder head, then processed from the upper part, prohibit the use of turning processing or from the bottom to the port of discharge treatment.6. When dealing with the lower funnel of the jaw crusher, it should be connected with the feeder and belt conveyor, and disconnect the belt conveyor, power switch, and send special personnel to monitor.
