Description

Technical Field

[0001] This invention relates to the field of crusher technology, specifically a vertical impact crusher. Background Technology

[0002] Crusher, also known as stone crusher, is a crushing machine used in the processing of metal and non-metal minerals. It can crush mined raw ore into small particles through compression and bending. Commonly used crushing machines include jaw crushers, gyratory crushers, cone crushers, roller crushers, hammer crushers, and impact crushers. They are widely used in various industries such as ores, cement, refractory materials, glass raw materials, manufactured building sand, stone, and various metallurgical slags.

[0003] When using an impact crusher, the material is fed into a rotating impeller, where it is rapidly accelerated and then ejected from the impeller's flow channel. The materials collide, rub, and crush against each other, and the crushed material is discharged from the discharge port at the bottom. However, existing crushers cannot classify and feed materials of different diameters. Smaller materials tend to leak through the gaps in the impeller, while larger materials can easily clog the impeller, affecting the normal operation of the impact crusher. Summary of the Invention
