Double-rotor scrap steel crusher and crushing method

Abstract

The invention discloses a double-rotor scrap steel crusher. The double-rotor scrap steel crusher comprises a feeding groove and a crushing bin, wherein the crushing bin comprises a box body and at least two crushing shafts, the crushing shafts are rotationally arranged in the box body in a driven mode, a plurality of crushing hammers are arranged on the crushing shafts, and a feeding hole of the crushing bin is positioned above one sides of the end parts of the crushing shafts. According to the double-rotor scrap steel crusher, the feeding mode that feeding is carried out above the end sides of the crushing shafts is adopted in a breakthrough mode, so that crushed materials are crushed while axially advancing along the crushing shafts, the crushing time is long, the breaking and striking points are large, and the large pieces of materials can be effectively crushed. In addition, due to the fact that the crushing hammers cannot be arranged on the material falling point side, the influence of the falling materials on the crushing hammers is effectively reduced, and the accidents such as jamming at the material falling point are avoided. Moreover, the feeding hole is formed in one side of the end part, so that the falling materials do not interfere with the materials hit in the crushing bin, and the feeding disorder is reduced.

Description

technical field [0001] The invention relates to the technical field of crushing machinery, in particular to a double-rotor scrap steel crusher. Background technique [0002] At present, there are mainly two types of scrap steel processing equipment: one is packing and briquetting equipment. It is mainly used to deal with light and thin materials such as thin plates, wire rods and chips produced in the machining process, so as to facilitate transportation and increase the stacking specific density; the second is shearing equipment. It is mainly used to process heavy steel scrap and large components, which is convenient for entering the furnace. The above two types of scrap processing equipment have the following disadvantages: the processing range is small, and they can only handle light and thin materials such as thin plates, wire rods, and chips produced during mechanical processing, as well as heavy scrap steel and large components, but they cannot handle scrapped cars, h...

Problems solved by technology

The above two types of scrap processing equipment have the following disadvantages: the processing range is small, and they can only handle light and thin materials such as thin plates, wire rods, and chips produced during mechanical processing, as well as heavy scrap steel and large components, but they cannot handle scrapped cars, household appliances, and extra-heavy Scrap and Large Components

[0004] However, the current crushers all have poor crushing capacity for bulk materials and are prone to jamming.
