Gravel crusher

Abstract

The invention provides a gravel crusher. The gravel crusher comprises a rack, a crushing machine box, a rotor, crushing hammer assemblies, a toothed plate and a screen plate, wherein the crushing machine box is arranged on the rack, the rotor is arranged inside the crushing machine box, the crushing hammer assemblies are uniformly arranged in the circumferential direction of the rotor, the toothed plate is arranged on the inner wall of the upper portion of the crushing machine box, the toothed plate is matched with the crushing hammer assemblies, the screen plate is arranged below the crushing machine box, a feeding hopper is arranged above the crushing machine box, a discharging hopper is arranged below the crushing machine box, and the discharging hopper is located below the screen plate. Materials can be crushed through cooperation of crushing hammers and the toothed plate, wherein the crushing hammer is of a split type structure, which facilitates replacement; and the toothed plate and the crushing hammer assemblies adopt an inverted V-shaped structure so that the resistance borne by the crushing hammer assemblies to strike materials can be reduced, and the service life of the toothed plate and the crushing hammer assemblies is prolonged.

Description

【Technical field】 [0001] The invention relates to the technical field of crushing equipment, in particular to a sandstone crusher. 【Background technique】 [0002] The hammer crusher mainly breaks the material through the high-speed rotating hammer body and the material collision surface. It has the characteristics of simple structure, large crushing ratio, and high production efficiency. It can be used for dry and wet crushing. It is suitable for mines, cement, coal, Metallurgy, building materials, roads, combustion and other departments are used for finely crushing medium hardness and brittle materials. The material is fed into the machine from the upper feeding port, and is pulverized by the impact, impact, shearing and grinding of the high-speed moving hammer. In the lower part of the rotor, there is a sieve plate, and the particle size smaller than the sieve hole size in the crushed material is discharged through the sieve plate, and the coarse particle size larger than...

AI Technical Summary

Problems solved by technology

During the production process, many shortcomings of the hammer crusher were found. The crushing process will generate a lot of dust, which will pollute the environment. The hammer head wears quickly and is inconvenient to replace. Processing natural minerals will generate a lot of heat energy, which will cause the material to agglomerate and block the sieve plate. This is easy to cause downtime, and a sand and gravel crusher is now proposed
