The Jaw crusher is the preferred device of primary crushing, and is also an efficient and energy-saving crushing equipment. The selection of the jaws determines the length of the lifetime of the jaw crusher. The operation method of the jaw crusher also determines the life of the jaw crusher.

Preparation before using the jaw crusher: (1) Carefully check if there is sufficient grease in the connection of the thrust plate; (2) carefully check if all fasteners are tight; (3) Carefully check whether the transmission belt is good. If there is an unsafe phenomenon, it should be replaced in time. When there is oil in the belt or the pulley, the application rag will wipe the oil; (4) Check whether the protective device is good. When there is an unsafe phenomenon, it should be excluded in time; (5) Check the ore or debris in the crushing chamber. If there is ore or debris, it must be cleaned to ensure that the crusher cavity is started; (6) Check if the top bolts are returned, whether the gasket is compressed, whether the T-shaped bolts are tightened.

The start of the jaw crusher: (1) After examination, it is proved that the various parts of the machine can be activated; (2) The molar is only allowed to start without load; (3) Being a ringtone or Signal warning; (4) After starting, if there is abnormal phenomenon, it should stop running immediately. When you find and exclude abnormal conditions, you can restart the crusher.

              
 

During the production of jaw crusher: (1) After the maneuver is operating normally, it can be pushed into the production; (2) The material to be broken is evenly added to the crusher cavity, and should avoid lateral feeding or stacking, so as not to avoid Unilateral overload or overload; (3) When operating normally, the temperature rise of the bearing should not exceed 30 ° C, and the maximum temperature must not exceed 70 ° C. When the above temperature is exceeded, stop immediately, identify the cause and exclude. (4) Before the parking, the addition should be stopped, and after the material is completely discharged, the power is turned off; (5) When it is broken, if there is a parking, it should immediately turn off the power to stop operation, will After cleaning the material in the broken cavity, it can be launched again; (6) After wear one end of the jaws, the head is used; (7) After using a period of time, the tightening bushing should be retracted to prevent tightening The load is loose and damage the machine.

When the jaw crusher is charged: (1) The tandem is continuously running 2h, and the bearing temperature rises must not exceed 30 ° C; (2) All fasteners of the jaw machine should be firm and no loosening; (3) flywheel, slot Wheel operation is stable; (4) All friction parts of the molar machine are free of strapping, cutting and grinding, and there is no normal sound; (5) The adjustment device of the molar discharge port should ensure the adjustment range of the exhaust port.

When the jaw crusher has a test: (1) The crusher must not have a cycle or a significant impact, hit the sound; (2) The maximum gum size should meet the design regulations; (3) Continuous operation 8 h, the bearing temperature rise must not exceed 30 ° C; (4) crusher treatment capacity and product particle size should comply with design regulations; (5) The adjustment seat and the rack ear room have no obvious movement.
