In the course of the work of Jaw Crusher, most of the human factor will cause the equipment overload. If the device is overloaded, the light is off, the internal components of the device is broken, so, after the crushing device has been overloaded, we should make what kind of measures to protect the equipment?
1, when the jaw crusher internal access to non crusher, the device's crushing force will increase, this time the pressure plate role in the working cylinder pressure will be higher than the hydraulic cylinder, so that the oil pressure in the oil chamber can lead to a transient rise. So we can equip the device with the throttle valve, through this valve can make the action of the valve, and then make the hydraulic cylinder automatic discharge, limit the thrust plate to protect the maximum thrust.
2, Rule out un-broken materials. Such practices can have two kinds of, first, stop, exclusion and adopted by the human the crushing cavity the non crushing matter; second, equipment automatically excluded, owing to limiting the maximum thrust by the working cylinder can provide, retraction of the piston is shifted to the right, corresponding jaw type crusher row ore mouth increases, by on jaw crushing the engagement of the movable jaw, the non crushing matter gradually downward movement and ultimately from the row ore mouth discharge. These two methods can’t be broken, and then protect the equipment. Overload is not desirable, regardless of the majority of users in the use of any crusher equipment, should avoid such phenomenon, in order to obtain the good results we want.
