Description

Technical Field

[0001] This utility model relates to the field of crusher technology, specifically to a metal waste crushing device. Background Technology

[0002] Metal scrap refers to metal fragments and shavings discarded in the metallurgical and metal processing industries, as well as metal objects from equipment upgrades and disposals. It also includes metal packaging containers and scrapped vehicles recovered from municipal waste. Recycled metal scrap is primarily used for smelting and refining into recycled metal, with some used in the production of machinery, equipment or parts, tools, and household appliances. The recycling of scrap metal not only contributes to resource conservation but also reduces negative environmental impacts.

[0003] Before recycling metal scrap, it is generally necessary to crush it to break down large, irregularly shaped pieces into smaller fragments. A metal shredder is a device that crushes scrap metal, using specific crushing mechanisms and processes to break the scrap metal into particles or blocks that meet the required specifications. Conventional metal shredders utilize the basic principle of hammer impact. Driven by a high-speed, high-torque motor, the hammers on the main rotor alternately strike the material to be crushed inside the crushing chamber. Through the space formed between the liner and the hammers, the material is torn into smaller, more sized pieces. While this type of metal shredder has a strong processing capacity, its pulling force is relatively weak, resulting in insufficient fineness of the crushed material, often requiring secondary crushing. Furthermore, this type of metal shredder has high energy consumption, generates significant noise, and is poorly suited for thin-walled metal scrap. Summary of the Invention

[0004] This utility model aims to address the technical deficiencies of existing technologies by providing a metal waste crushing device to solve the technical problems of conventional metal crushers, such as insufficient fineness in processing thin-walled metal waste, high noise levels, and high energy consumption.

Several support bodies are fixedly connected to the bottom of the crushing bucket. The top of the crushing bucket has an upper port, with guide ramps on the left and right sides of the upper port. The bottom of the crushing bucket has a discharge port, and enclosures are located on the front and rear sides of the upper port. A pair of main crushing rollers are arranged inside the crushing bucket, and a peripheral crushing roller assembly is arranged around the pair of main crushing rollers.
