Description

Heavy impact crusher

Technical Field

The utility model relates to the technical field of crushers, in particular to a heavy impact crusher.

Background

The impact crusher is crushing equipment with relatively large market share, when the crushing equipment is crushed, a certain angle is formed between the crushing equipment and the tangent line of the plate hammer after the acting force of the plate hammer, so that the crushing equipment is used for explanation of popular point language, namely, the material is subjected to horizontal throwing motion in the impact crusher, then is rebounded by another plate hammer to continue crushing until the smaller material is formed, and the material is subjected to tangent motion relative to the plate hammer until the material is crushed into ideal granularity and then is discharged out of the crusher body, and the impact crusher is particularly suitable for crushing mine coal and coal gangue. Impact crusher is divided into hammer type and impact type, and the hammer head rotating at high speed strikes the rock to be crushed. The rock mass is crushed while obtaining a great amount of kinetic energy, forming a secondary crushing in its collision with the impact plate and other rock masses. The rock rebounded back from the impact plate repeats the above process again, eventually discharging the acceptable grain size product. Because the impact crusher fuses various crushing principles such as shearing, impact, beating, grinding and the like in the crushing process, the kinetic energy of the rotor and the space of the crushing cavity are fully utilized, and therefore, compared with a roller crusher, a jaw crusher cone crusher and the like which are mainly crushed by the extrusion force of the machine , the impact crusher cone crusher has the advantages of good product particles, large crushing ratio, high cube form proportion, fine and uniform discharging, convenient maintenance, lower energy consumption and the like. Meanwhile, the impact crusher is widely used for fine crushing before grinding, so that the granularity of the materials to be ground of the mill is greatly reduced, and the effect of replacing grinding with crushing is achieved.

The existing impact crusher has the following defects when in use: 1. the shape of the impact area is the same, so that the particle type of the final discharge is poor, the descending speed of the second material is slower, the crushing efficiency is lower, the particle size cannot be adjusted, and the use is inconvenient.
