Principle

When the fine crusher works, the motor drives the eccentric shaft to rotate through the pulley, so that the moving ring is periodically close to and away from the fixed boring, so that the material has multiple crushing, smashing, rolling, etc., so that the material becomes larger and smaller, and gradually falls. Until it is discharged from the discharge opening.

1, the raft can be exchanged between the upper and lower heads: the fixed raft is fastened to the front wall of the frame by pressing bolts, and the movable sill is pressed against the movable raft by the bead, when the stern is worn (usually the lower end wears more) , the two can be changed position, continue to use.
2, protection: the bracket in addition to the supporting movement, so that it runs according to a certain axis, when the broken cavity enters the foreign object that can not be broken and the load increases sharply, it plays the insurance role, that is, the load is cut off by itself Protect other parts from damage.
3. How to adjust the discharge granularity: the adjustment seat is suspended by the T-bolt on the ear seat on both sides of the frame, and there is a set of adjustment gasket between the adjustment seat and the rear wall of the frame, and the function is to open the adjustment seat of the bolt. The width of the discharge opening can be adjusted by changing the thickness of the gasket to obtain the desired product size.
4. The function of the tension spring is: the tension spring device is used to ensure the tight combination of the entire mechanism of the jaw crusher, and partially balance the inertia force generated when the jaw and the bracket work, and the spring when the crusher works The pressure should not be too large, as long as it can eliminate the impact of the bracket and the movement of the bracket.
