Impact crusher

Abstract

The invention discloses an impact crusher. The impact crusher comprises a rotor body, a flattening plate and a flattening cavity formed by the rotor body and the flattening plate; and an impact baffle plate device is arranged on the line of the material throwing direction of a discharging hole of the flattening cavity. A set angle between the toothed plate surface of a toothed plate and the line of the material throwing direction of the discharging hole of the flattening cavity is kept. The impact baffle plate device comprises a plate frame and the toothed plate; the toothed plate is arranged on the plate frame; the lower part of the plate frame is provided with an invertedly hooked structure; the lower part of the toothed plate is provided with an oblique angle groove matched with the lower part of the toothed plate; and an L-shaped press block presses the toothed plate tightly and is tightly fixed on the plate frame by a bolt pair. In the impact crusher, the impact baffle plate device is arranged to effectively prevent materials from impacting a crusher body and civil foundation so as to avoid damage accident. Meanwhile, the crushing efficiency of the crusher can be improved, and the discharging grain size can be effectively reduced and the qualification rate of a material finished product can be improved. The impact baffle plate device has the characteristics of simple structure and the like, is convenient to mount and maintain, and runs safely and reliably.

Description

technical field [0001] The invention relates to a crusher in the field of material crushing machinery, in particular to an impact crusher. Background technique [0002] Impact crushers are widely used in the crushing of raw materials in metallurgy, mining, building materials, road construction, chemical and cement industries. Such as Figure 4 As shown, it is mainly composed of shell, rotor body, first impact plate, second impact plate and leveling plate. It uses the high-speed rotating striking plate to break the material block, and the material is crushed by the crushing cavity and the uniform cavity, and then it becomes the finished material particle size and is discharged from the crusher. As we all know, the impact crusher is a one-way crushing channel. The leveling device can only control the radial distance from the rotor body, and the axial direction is a crushing belt with the same width as the crusher cavity. The structural characteristics of the impact crusher no...

As we all know, the impact crusher is a one-way crushing channel. The leveling device can only control the radial distance from the rotor body, and the axial direction is a crushing belt with the same width as the crusher cavity. The structural characteristics of the impact crusher not only cause It cannot fully control the discharge particle size of the material, that is, the material that does not meet the discharge particle size may also be discharged from the crusher, and the discharged material will have a large kinetic energy, causing serious damage to the crusher body, civil foundation and conveyor belt.
