Technical Field
[0001] The utility model belongs to the technical field of impact crushers, in particular to a crushing gap adjustment device for an impact crusher. Background Art
[0002] Impact crusher has the advantages of simple structure, large crushing ratio, low energy consumption, high output, and cubic shape of materials after crushing. It can be used for medium and fine crushing of various medium hardness materials with compressive strength not higher than 100Mpa, such as limestone, clinker, slag, coke, coal, etc. in mining, cement, construction, refractory materials, coal, glass and other industrial sectors.
[0003] The impact plate inside the existing impact crusher is usually fixed, which is not conducive to adjusting the gap between the impact plate and the crushing roller. When the material to be crushed is large, the fixed gap cannot effectively crush the material by impact, and it is easy to get blocked, causing the crushing roller to get stuck, which not only affects the normal operation of the crusher, but also requires cleaning and dredging inside, reducing work efficiency.
