Causes of Jaw Plate fracture and maintenance methods

1. The process of the jaw plate is not perfect during casting, and there are serious defects such as dense pores inside.

2. The movable jaw is displaced in the frame, and the bottom of one end collides with the frame side guard plate.

3. The tension of the pull rod spring fails and is not replaced in time.

4. The discharge port is smaller than the specified range, the feeding position is incorrect, it is biased to one end or the angle of the lower hopper is too steep, so that the material directly hits the head of the movable jaw.

5. The equipment uses unqualified toggle plates and toggle plate pads, resulting in the jaw crusher not breaking off when it is subjected to strong impact.

Maintenance method: The two jaw plates use excellent casting technology, and the internal structure is tight; adjust the size of the feed port according to the specification parameters, feed continuously and evenly, and ensure that the feeding position is in the middle; replace damaged accessories such as pull rod springs, toggle plates, toggle plate pads, and adjust the angle of the lower hopper.
