Description

Technical Field

[0002] Hammer crusher is a kind of equipment that crushes materials in the form of impact. It is divided into single rotor and double rotor. It is a crusher that directly crushes materials with a maximum particle size of 600-1800 mm to 25 or less. Hammer crusher is suitable for medium and fine crushing of materials with medium hardness in cement, chemical, electric power, metallurgy and other industrial sectors, such as limestone, slag, coke, coal and other materials. In the document with publication number CN212915900U, a hammer crusher is proposed. When the materials with larger particle size on the screen plate accumulate to a certain extent, the compression spring of the screen plate moves downward. Due to the inclined setting of the screen plate, the materials on the screen plate can slide from the screen plate to the collection port, avoiding the screen plate being blocked by the larger particle size on the screen plate, affecting the screening effect of the screen plate. When the above-mentioned hammer crusher is in use, because the materials on the screen plate are not cleaned from the outside, the materials are easily stuck in the holes of the screen, affecting the normal screening of the materials.
