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.
