Steel slag is the waste slag produced in the metallurgical industry, a by-product in the steelmaking process, and its production rate is 8%-15% of the crude steel output. With the rapid development of the steel industry, it is increasing rapidly, and the problem of resource utilization is becoming more and more serious. The more attention is paid, can Raymond mill grind steel slag? Let's take a look.

 

As long as steel slag is composed of various oxides formed by oxidation of silicon, manganese, phosphorus, sulfur and other impurities in pig iron during the smelting process and salts formed by reacting with solvents, the Mohs hardness is 5-7, and its strength is relatively high. High, hard texture, difficult to handle, and Raymond mill can process various non-flammable and explosive minerals with Mohs hardness below 7 and humidity below 6%. The finished steel slag powder is 0.173-0.044mm (80-360 mesh ), the effect is very good.

 

Moreover, steel slag is processed into fine powder by Raymond mill, which can replace limestone powder, and a large amount of metallic iron and other useful elements can be recovered from it. In addition, it can also be used as raw materials for making road construction materials, building materials or agricultural fertilizers.

 

The principle of the steel slag mill: when working, put the material to be crushed into the machine from the hopper on the side of the machine cover, and rely on the grinding roller device suspended on the plum blossom frame of the main machine to revolve around the vertical axis and at the same time rotate itself. Under the action of centrifugal force during rotation, the grinding roller swings outwards and presses tightly on the grinding ring, so that the spatula scoops up the material and sends it between the grinding roller and the grinding ring, and achieves the purpose of crushing the material due to the rolling and rolling of the grinding roller.
