The full name of “slag” is “granulated blast furnace slag”, which is the waste residue produced when the iron and steel plant smelts pig iron. In addition to iron ore and fuel (coke) in the blast furnace ironmaking process, an appropriate amount is added to reduce the smelting temperature. The limestone and dolomite serve as fluxes, and the calcium oxide and magnesium oxide obtained by the decomposition in the blast furnace, and the waste ores in the iron ore, and the ash in the coke are melted to generate silicates and aluminosilicates. The molten salt, which is the main component, floats on the surface of the molten iron and is discharged from the slag discharge port periodically. It is quenched by air or water to form granular particles. This is granulated blast furnace slag.

Chaeng has more than 50 years of experience in the production of vertica roller mills,we have  the largest production base of slag grinding mill in China, focuses on the production of large and medium-sized vertical mills, quality assurance, and we has a good reputation in the industrial milling machine market with high quality service.  Vertical roller mill machine is widely used in metallurgy, building materials, chemical industry, mining and other areas of mineral materials, grinding process, suitable for processing Mohs hardness less than seven, humidity below 6% of a variety of non-inflammable and explosive minerals, Such as gypsum, talc, calcite, limestone, marble, potassium feldspar, barite, dolomite, granite, kaolin, bentonite, medical stone, bauxite, red iron oxide, iron ore, etc., the finished fineness of 613 microns Between ~440 micron (0.613 mm - 0.44 mm), through the interaction of the analysis machine and the fan, it can meet the requirements of different users. The use of the same power vertical mill product for the micro-powder processing of slag, can stimulate the slag hydraulicity, that is, the use of high-fine grinding and ultra-fine grinding method.
