Steel slag is waste slag produced in the metallurgical industry. Its production rate is 8%-15% of crude steel production. It is increasing rapidly with the rapid development of the steel industry. Therefore, the issue of resource utilization has also received more and more attention. Currently, there are two There are two main ways. One is to be recycled in the factory as a smelting solvent, which can replace limestone, and the other is to be used as a raw material for manufacturing road construction, construction or agricultural fertilizers. However, what are the technological processes for steel slag treatment? How much does steel slag processing equipment cost? Let’s take a look next.

What are the technological processes for slag treatment?
Steel slag is mainly composed of various oxides formed by the oxidation of silicon, manganese, phosphorus, sulfur and other impurities in pig iron during the smelting process, as well as salts generated by reaction with solvents. Mohs hardness is 5-7, and its strength is relatively high. High, hard texture, difficult to crush, the most commonly used equipment are jaw crushers, cone crushers, impact sand making machines, ball mills and other equipment. There are three types of steel slag treatment processes, which are detailed as follows.

Steel slag crushing production line process flow

Raw materials → Vibrating feeder → Jaw crusher → Cone crusher → Vibrating screen → Conveyor → Finished product;

This kind of steel slag treatment process mainly produces 12 and 13 stone, and is equipped with a jaw crusher and a cone crusher. In use, it avoids equipment wear due to high hardness and solves the problem of high operating costs in the later period.

Steel slag sand making process

Raw materials → Vibrating feeder → Jaw crusher → Cone crusher → Impact sand making machine → Vibrating screen → Conveyor → Finished product;

It is suitable for customers who require sand for finished products, that is, machine-made sand with a particle size of 0.25-0.5mm. An impact sand making machine is added behind the cone crusher to improve the particle shape and quality of the finished product. It is multi-angular and has a rough and porous particle surface. , and has honeycomb-shaped fine steel slag particles, which have strong pressure resistance and good pit rupture ability. In terms of performance, it is relatively in line with the standards for sand used in construction projects.

Steel slag ball mill process flow

Raw materials → Vibrating feeder → Jaw crusher → Cone crusher → Vibrating screen → Steel slag ball mill → Spiral classifier → Magnetic separator → Flotation machine → Concentrator → Dryer → Finished product;

It is also called the steel slag micro powder production process. If the demand for the finished product is about 24-200 mesh (0.074-0.89mm), you can choose this process. The grinding is finer, full and has strong adhesion. Through grinding with different grades Medium, which can reduce the phenomenon of product over-powder.
