Structural improvement of the simple pendulum jaw crusher

The simple pendulum jaw crusher to break material by the cyclical movement of the movable jaw. The fixed jaw swinging the process of moving the jaw around the hanging heart axial asked in the two jaw material will be squeezed, splitting and bending combined effects of beginning, less stressful, so that the material volume is reduced, the material close to each other, squeezing, when the pressure rose to exceed the material strength can bear, that is fractured. When the movable jaw to leave the fixed jaw to swing in the opposite direction, the material by gravity downward movement. The moving jaw of each cyclical movement will cause the material by first crushing the role, and the carriage of some distance. After several cycles, the crushing of materials begins with the discharge opening from the plane.

Simple pendulum jaw crushers structure, belonging to six organizations in the crank rocker mechanism the application, where the crank is the driving part.

Simple pendulum jaw crusher, vertical travel of the movable jaw is small, and overcome the shortcomings of the compound pendulum jaw crusher vertical travel, but the stroke of the upper level (the upper part of the crushing chamber are larger nugget, For broken themrequire a greater level of travel), Therefore, the crusher can not fully meet the broken ore to the required compression, crushing the poor. If you increase the level of the upper movable jaw travel is bound to make the lower level of travel increases, resulting in the product particle size is more uneven. In order to eliminate this defect, on the basis of foreign experience, will generally simple pendulum jaw crusher to improve-lift mandrel, that is, the spindle position of the movable jaw and move forward to the crushing chamber nip angle angle bisector.
