Technical Field

[0001] The utility model belongs to the technical field of crushers, in particular to a crusher for recycling and processing waste steel materials. Background Art

[0002] Scrap steel includes industrial scrap steel, construction scrap steel, etc. For example, construction scrap steel refers to steel waste generated during the construction process, including scrap rebar, scrap steel pipes, scrap iron plates, etc. Most of them can be recycled as renewable resources.

[0003] When recycling scrap steel, most people currently use crushers to crush the steel. The steel is put into the crusher and crushed with the crushing rollers inside the crusher. At the same time, the materials that meet the requirements are filtered out through the screen.

[0004] After the scrap steel is crushed, the materials that meet the requirements are discharged through the discharge port, and the large pieces of materials that do not meet the requirements need to be crushed again. When the large pieces of materials are put into the crusher again, most of them need to be transported by a cart, and then according to the height of the crusher, a lifting device is used to put the large pieces of materials into the crusher. The operation is relatively complicated, time-consuming and labor-intensive. Utility Model Content
