Problems solved by technology
[0003] The steel slag has the following problems in the process of recycling: 1. The surface of the steel slag often sticks to each other with impurities such as silicon, manganese, phosphorus, and sulfur. It is not completely separated from impurities, so that there is too much impurity in the collected iron particles; 2. After the steel slag is broken, it is divided into iron nuggets, impurities, iron powder and dust. It is necessary to collect iron nuggets and iron powder during sorting, but in When removing dust inside the device, it is easy to absorb iron powder together, thus reducing the comprehensive utilization rate of steel slag

Embodiment Construction
[0027] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.
[0028] Such as Figure 1 to Figure 5 As shown, a comprehensive utilization and processing system for steel smelting waste steel slag includes a base 1, a crushing unit 2 and a sorting unit 3. The selection unit 3; the crushing unit 2 crushes the steel slag again, and the sorting unit 3 separates and collects iron nuggets, impurities, iron powder and dust, so as to obtain recyclable iron nuggets and iron powder.
[0029] The crushing unit 2 includes a rotating cylinder frame 21, a rotating cylinder 22, a feeding arc plate 23, a driving mechanism 24, a material guiding rotating plate 25, a discharging rotating plate 26, a belt plate 27, a crushed steel ball 28 and a lower The material pipe 29 and the drum frame 21 are arranged on the upper end of...

The invention relates to a comprehensive utilization and processing system and method for steel refining waste steel slag, comprising a base, a crushing unit and a sorting unit. Selection unit; the invention adopts the method of ball collision and crushing for secondary crushing of the steel slag, and impacts the steel slag from multiple directions, which solves the problem that the jaw crusher cannot crush all the steel slag. Separation; the present invention adsorbs iron blocks and iron powders on the belt surface by using magnetic force, and at the same time causes impurities to be guided to the waste frame along the belt track, so that impurities are separated from iron blocks and iron powders. The dust removal mechanism does not clean the iron powder, which further improves the comprehensive utilization rate of the steel slag.
Description
technical field [0001] The invention relates to the technical field of iron and steel refining industry, in particular to a system and method for comprehensive utilization and processing of waste steel slag in iron and steel refining. Background technique [0002] Steel slag is waste slag produced in the metallurgical industry, and its production rate is 8% to 15% of crude steel production. In 2012, the amount of steel slag discharged in the world was about 180 million tons. The amount of steel slag produced in China is increasing rapidly with the rapid development of the iron and steel industry. Therefore, the treatment and resource utilization of waste slag in iron and steel enterprises have also been paid more and more attention. [0003] The steel slag has the following problems in the process of recycling: 1. The surface of the steel slag often sticks to each other with impurities such as silicon, manganese, phosphorus, and sulfur. It is not completely separated from i...
