Slag is also known as dross, it is a melt floating on the surface of the liquid metal which generated during hydrometallurgical process , main composition is oxide , but also entrain a small amounts of metal and sulfides. Slag is a kind of solid industrial waste with large displacement, if we ignore the treatment to the large amounts of slag that will not only result in a waste of resources, but also take up a lot of land. Take steel slag as an example, annual emissions have reached up to 80 million tons at present, occupancy about 15 % -20 % in crude steel production.
The slag wastes turn into treasure after process by slag crusher equipment; it can be used in different fields. For some examples, blast furnace slag can be used as a raw material in making cement; high phosphorus slag can be used in making fertilizer; slag containing vanadium, titanium can be used to extract vanadium, titanium. Clinker slag can be used to make bricks, slag glass and so on, the slag also can be used as building materials, insulation materials and insulation materials In a word, and slag has been widely used in various fields of industry and agriculture.
In slag recycling line, we select the appropriate crushing and screening equipment according to the characteristics of slag and the requirement of final product. At first, carry pure iron out from slag before process to avoid causing damage to the crusher equipment. Second, transport the large pieces of slag carried evenly into jaw crusher to make primary crushing, third, the primary crushing slag will be transported to slag impact crusher make fine crushing. Usually we need a vibrating screen for the crushed slag, particle size meet the requirements will be shipped to the next device, the others will return to upper crusher equipment. Depending on different needs, customers can add a grinding mill to grind the slag into powder, so that it can be used in making bricks, cement and others.
Shanghai Shibang Machinery have rich experience in production of slag crusher, it's a efficient crusher designed by our engineers whom independent research and development on absorption the foreign advanced technology. It is made of impact resistance and wear-resistant material, significantly improved the life of the machine, reducing the consumption of vulnerable part. After optimized design, the slag crusher has larger carrying capacity and more efficiently, it's the best crusher in slag recycling line.
