Jaw crushers are commonly known as jaw crushers and also known as old tiger jaws. The crushing cavity is formed by two jaw plates, namely a movable jaw plate and a static jaw plate, and the crusher simulates the movement of the two jaws of animals 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. The working part of the traditional jaw crusher comprises a static jaw plate and a movable jaw plate, wherein the static jaw plate is vertically fixed on the machine body, and the movable jaw plate is obliquely arranged on the machine body and forms a crushing cavity with the static jaw plate in a large upper part and a small lower part. When in operation, the movable jaw plate moves back and forth against the static jaw plate periodically, and is separated and closed. After the materials enter the crushing cavity, when the movable jaw plate approaches the static jaw plate, the materials arranged on the two jaw plates are crushed by extrusion, bending and splitting, and when the movable jaw plates are separated, the materials fall from the lower part of the crushing cavity under the action of gravity.
However, as the crushing jaw plate does not move axially in the swinging motion, the crushed materials are swung away from the fixed jaw by the movable jaw to generate a space, and gradually and naturally fall down to discharge materials according to gravity. Therefore, the method determines that only hard and non-sticky materials can be crushed, wet sticky materials cannot be crushed, the sticky materials are easy to adhere to jaw plates and cannot fall down to discharge materials, and gaps at the bottoms of the jaw plates cannot be made very thin to mainly consider blockage, so that the primary crushing particle size range is relatively smaller, and the method cannot be directly used for crushing to small particles.
