Background

As basic engineering machinery for material crushing, crushing equipment is widely applied to various fields such as mining, traffic construction, metallurgy, chemical industry, electric power, water conservancy, real estate and the like. Among them, the impact crusher (commonly known as "sand making machine") plays an irreplaceable role in the fine crushing field due to its advantages of high energy consumption, simple structure, low maintenance cost, etc.

Generally, the impact crusher mainly uses the principle of 'stone beating', and uses stones (or other materials) thrown by an impeller and naturally falling stones to collide with each other in a crushing cavity so as to achieve the purpose of crushing. Therefore, the crushing efficiency can be increased to obtain a higher sand forming rate by improving the collision efficiency in the crushing cavity.

Therefore, the impeller continuously throws the materials into the crushing cavity, the materials flying out of the impeller and waterfall overflow stones and the like are beaten, collided and recombined in the crushing cavity, but the stagnation time of the materials in the crushing cavity is short, part of the materials cannot fully participate in repeated and cyclic beating crushing, and the sand forming rate cannot be effectively improved.
