The material enters the crusher from the feed hopper, directly enters the rotor rotating at high speed through the central feeding pipe and is rapidly accelerated, the acceleration can reach hundreds of times of gravity acceleration, then is ejected out from a flow passage uniformly distributed by the rotor at the speed of 50 to 75 m/s and impacts the reaction rod of the vortex cavity to be rebounded, the motion direction of the reaction rod is changed, the material emitted from the rotor flow passage forms a continuous material curtain, thus, one material is impacted, rubbed and ground and crushed twice at most times in the vortex cavity, the crushed material is discharged from a lower discharge port, and a closed circuit is formed through a circulating screening system;
2. the two move in different ways
Although the patent of CN104148139a discloses a prismatic roller with a plurality of crushing surfaces, the crushing of the material is to crush the material by two oppositely moving paired rollers, and the material is easy to slide and jump upwards in the process of being crushed, so the prismatic roller is designed to clamp the material during crushing, increase the friction between the material and the paired rollers, and is beneficial to pushing the material, thereby solving the problem that the material cannot be fed because the material slides on the roller surface;
the invention is characterized in that the material is thrown into the crushing cavity continuously from the high-speed rotating rotor in an accelerating way to form a material impact bar crushing mode, and the material is thrown out at high speed along the tangential direction of the excircle of the rotor body in the material throwing process, so that the prismatic impact bar is designed to increase the impact surface of the material, and the prismatic impact bar is designed to be used for the maximum efficiency, so that the production capacity of the crusher, the utilization rate of the impact bar and the grain shape of the sand forming rate can be improved.
Has the beneficial effects that: according to the invention, the counterattack rod is arranged into the prism shape, so that the counterattack rod is provided with a plurality of counterattack surfaces, when a certain counterattack surface is worn, the counterattack rod can be rotated by a certain angle, and the other side surface of the other prism is taken as the counterattack surface to continue production, so that the utilization rate of the counterattack rod is improved, the conditions of low sand making rate and low material utilization rate of the cylindrical counterattack rod during sand making are overcome, the high sand making rate of the counterattack rod is realized, the utilization rate of the material is improved, and the high yield and the low energy consumption are realized; the fixing part and the cylindrical positioning part which are regular quadrangular prism-shaped are respectively arranged at the upper part and the lower part of the counterattack rod, so that not only is the four surfaces of the fixing part fixed through the pressing block convenient, but also a certain angle of rotation is convenient.
