Problems solved by technology

[0003] I have seen that there are three main sources of scrap iron and steel: self-produced scrap iron and steel in steel mills, social recycled scrap iron and steel, and imported scrap iron and steel. Among them, social recycled scrap iron and steel accounts for a large proportion, but the surface of social recycled scrap iron and steel is pasted with plastic film, rubber, Combustible debris such as paper, sponge, fiber, wood, oil stains, etc. These combustible debris are firmly attached to scrap steel and difficult to remove

Abstract

The invention relates to a scrap steel breaking and impurity removing machine. The scrap steel breaking and impurity removing machine comprises a primary breaker, a combustor, a secondary breaker, a lifting machine and a winnowing machine. The scrap steel breaking and impurity removing machine has the beneficial effects that scrap steel blocks are broken to form scrap steel sheets with the diameter smaller than 4 centimeters through the primary breaker, then combustible impurity objects on the surfaces of the scrap steel sheets which enter the combustor can be burnt through the combustor, thescrap steel sheets which are discharged from the combustor are conveyed to the secondary breaker through the lifting machine, then the scrap steel sheets which are burnt by the combustor are broken toform scrap steel particles with the diameter smaller than 1 centimeter through the secondary breaker, combustion ash can be separated from the scrap steel sheets at the same time, finally the scrap steel particles entering the winnowing machine and the combustion ash entering the winnowing machine are separated through the winnowing machine, and therefore the purpose that the combustible impurityobjects which adhere to the surface of scrap steel are moved is achieved, and the iron and steel scrap which is recovered from the society is conveniently smelted by an iron and steel company.

Description

technical field [0001] The invention relates to the field of scrap steel crushers, in particular to a scrap steel crushing and impurity removal machine. Background technique [0002] With the rapid development of the iron and steel industry, the price of iron ore has been rising year by year. At the same time, with the development of scrap iron and steel recycling technology, the demand for scrap iron and steel raw materials has also increased. [0003] I have seen that there are three main sources of scrap iron and steel: self-produced scrap iron and steel in steel mills, social recycled scrap iron and steel, and imported scrap iron and steel. Among them, social recycled scrap iron and steel accounts for a large proportion, but the surface of social recycled scrap iron and steel is pasted with plastic film, rubber, Combustible debris such as paper, sponge, fiber, wood, oil stains, etc. These combustible debris are firmly attached to scrap steel and difficult to remove.
