Strong counterattack crusher

Abstract

The invention discloses a strong counterattack crusher which comprises a rotor body, a first counterattack plate, a second counterattack plate, a mainframe of a balanced plate and a power-transmitting part, wherein the rotor body is provided with a base, a front box body, a rear box cover and a cylindrical surface, and a plurality of flat hammers are evenly distributed on the cylindrical surface; a first crushing cavity which is formed on the first counterattack plate relative to the rotor body is in an envelope curve shape; an adjusting device is arranged on a pull rod, and a protecting device is arranged on the pull rod; a pair of open-close mechanisms is arranged between two side plates of the rear box cover and two side plates of the base; one surface of each flat hammer is provided with a protrudent plug on the height central line of the plat hammer, and the other surface is provided with two protrudent plugs taking the height central line as a symmetric line; and the flat hammers are fixed on a rotor plate through compact plates of slots which are matched with the plugs of the flat hammers. The invention ensures that the functions of three crushing cavities are fully utilized, the granularity of finished product is moderate, and the percentage of granular small-granularity stone material is greatly increased.

Description

technical field [0001] The invention relates to a powerful impact crusher. Background technique [0002] The impact crusher can process various coarse, medium and fine materials (granite, limestone, concrete, etc.) with a side length of no more than 500mm and a compressive strength of no more than 350MPa. It is widely used in industries such as hydropower, highways, artificial sand and gravel, and crushing. . When working, driven by the motor, the rotor rotates at a high speed. After the material enters, it collides with the blow bar on the rotor and breaks, and then is counterattacked to the liner to be broken again, and finally discharged from the discharge port. [0003] Compared with other types of crushers, stones crushed by impact crushers have a good natural cubic shape and less needle flake content. With the increase of high-grade pavement construction and the increasing demand for high-grade buildings in high-rise buildings, the current standards have more stringe...

AI Technical Summary

Problems solved by technology

That is to say, the first crushing chamber does not play its role fully, which increases the crushing pressure of the second crushing chamber and the leveling chamber. The result is that in the finished stone, the proportion of formed small-grained stone is low, that is, mining There is no small problem with the stone hammering reflected on the stone site
