Description

Technical Field

[0001] The invention relates to a high-efficiency and stable crusher. Background Art

[0002] Roller crushers are widely used for crushing materials. For example, in the invention application with application publication number CN 111167549 A, entitled "Roller crushing device", a roller crushing device is disclosed, which includes a frame, a first roller, a second roller matched with the first roller, and a driving device for driving the first roller and / or the second roller to rotate, wherein the first roller is arranged above the second roller, the first roller is mounted on a movable pressing frame, and the movable pressing frame is mounted on the frame through a swing shaft.

[0003] There are several problems with this type of roller crusher when it is in use: 1. When crushing hard materials, such as stones, the first roller needs to be a heavy roller. When the first roller swings with the movable pressure frame, it will produce a large impact force on the frame, which is easy to damage. In addition, it will also produce a lot of noise. At the same time, the first roller has a large swing amplitude, needs to overcome a large weight, and has high energy consumption. 2. The material is transported to the space between the first roller and the second roller through the chute plate, and the material is crushed by the first and second rollers. During the crushing process, the material has a greater tendency to slide out from both ends of the second roller axis. Sometimes the material slides away from both ends of the second roller before it can be crushed, resulting in uneven crushing of the material, which needs to be crushed again, affecting the crushing efficiency.
