Background

Jaw crushers are commonly known as jaw crushes, also known as old tiger mouths. A crushing cavity is formed by two jaw plates of a movable jaw and a static jaw, and the crusher simulates the movement of the two jaws of an animal to finish the crushing operation of materials. The crushing device is widely applied to crushing various ores and massive materials in industries such as mine smelting, building materials, highways, railways, water conservancy, chemical industry and the like. The highest compressive strength of the crushed material is 320Mpa. Commonly used jaw crushers have two types of double toggle plates and single toggle plates. The movable jaw only swings in a simple arc during working, so that the movable jaw is also called a simple swinging jaw crusher; the latter also moves up and down while swinging in circular arc.

When the existing jaw crusher is used for discharging, a large amount of materials are generally fed from the upper part of the jaw crusher body at one time, although the feeding mode is relatively quick, the flow is not easy to control, and excessive materials can cause larger impact and damage to the jaw crusher body, so that the fixed jaw plate and the movable jaw plate are easily damaged, and the service life is influenced. We therefore propose a jaw crusher to solve the above problems.
