Description

Technical Field

[0001] The utility model belongs to the technical field of hammer crushers, and in particular relates to a reversible impact hammer crusher with a dust reduction structure. Background Art

[0002] The reversible impact hammer crusher is a new type of crushing equipment whose crushing rotor can be forward and reverse. The reversible double impact hammer crusher mainly relies on impact to crush materials. After the fallen materials enter the crusher, they encounter the high-speed rotating hammer head for the first crushing. After the crushing, the materials with basically the same particles evenly enter the main crushing chamber for secondary main crushing. The homogenized material particles in the main crushing chamber obtain kinetic energy from the hammer head again, rush to the serrated lining plate inside the counter-attack chamber at high speed, and are crushed by the hammer head again after the upward rebound of the serrated lining plate. At the same time, the materials are also crushed by the impact between each other. This cycle is repeated, and they are crushed many times in the counter-attack chamber. Finally, the crushed materials are discharged from the discharge port. However, the device still has the following defects: When the above equipment is in use, the reversible impact hammer crusher mainly relies on impact to crush materials. During the crushing process, the materials are hit by the high-speed rotating hammer head and crushed into fine particles. During this process, the collision between materials, the impact of the hammer on the materials, and the friction between the materials and the lining plate and other parts inside the crusher will generate a lot of dust. Crushing operations are usually carried out in an open or semi-open environment, which makes the generated dust easily spread into the air. If there are no effective dust reduction measures, the dust will not only affect the visibility of the production site, increase the difficulty of operation and safety hazards, but also may pollute the surrounding ecological environment.
