Scrap crusher plays a vital role in the recycling of scrap steel resources and has a good application and development prospect.

The effective recycling and utilization of scrap metal resources can greatly reduce the consumption of natural mineral resources, achieve the purpose of reducing land occupation, reducing total social energy consumption, saving investment, protecting the ecological environment, and improving labor production efficiency. Especially in the extreme consumption of natural mineral resources and increasingly scarce today, scrap metal resources in the world economy. The position of sustainable development strategy becomes more prominent. Since 2000, all countries in the world have been actively and effectively recycling scrap metal resources in order to appropriately curb the long-term excessive consumption of mineral resources and energy. Scrap iron and steel is the only raw material that can replace iron ore in iron and steel production. To develop and apply scrap iron and steel resources to the maximum extent is an important way to realize energy saving and emission reduction, clean production, circular economy and alleviate the crisis of iron and steel resources.

The work required to break the material is proportional to the newly added surface area in the crushing process. In fact, the work consumed by the newly added surface area in the crushing process is only a small part of the work required for the crushing of the material. Most of the work required for material crushing is consumed in deformation work, friction work, work consumed by particle surface structure and internal structure changes, as well as noise and heat loss. Volume hypothesis: the material is deformed by external force, so that the internal stress, when the external force reaches the strength limit of the material, the material deformation is too large, broken into small pieces, crusher material crushing consumption of work occurs on the deformation.
