Problems solved by technology

[0004] In this way, the impeller continuously throws materials into the crushing cavity, and the materials flying out of the impeller and the waterfall overflow stones are hit, collided and recombined in the crushing cavity, but the stagnation time of the materials in the crushing cavity is short, and some materials It may not be able to fully participate in repeated and cyclical beating and crushing, and cannot effectively increase the sand forming rate

Abstract

Relating to the field of engineering machinery, the invention discloses an impeller component and an impact crusher. The impeller component includes: an impeller (10), which is driven by a rotating driving device to throw out a material falling into an inner cavity (11) of the impeller (10), and at least a set of upthrow opposite pieces (20) arranged along the circumference of the impeller (10), the upthrow opposite pieces (20) protrude from the impeller (10) and form a material upthrow surface (21) capable of colliding with the material falling from above so as to increase the material density in the crushing chamber and enhance the collision probability, thereby increasing the sand-forming rate.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to an impeller assembly and an impact crusher. Background technique [0002] As the basic construction machinery for material crushing, crushing equipment is widely used in many fields such as mining, transportation construction, metallurgy, chemical industry, electric power, water conservancy and real estate. Among them, the impact crusher (commonly known as "sand making machine") plays an irreplaceable role in the field of fine crushing due to its advantages of high energy and low consumption, simple structure, and low maintenance cost. [0003] Generally, impact crushers mainly use the principle of "rock hitting rock", and use the stones (or other materials) thrown by the impeller to collide with the naturally falling stones in the crushing cavity to achieve the purpose of crushing. Therefore, the crushing efficiency can be increased to obtain a higher sand forming rate by i...
