The importance of vertical roller mill in the treatment of nickel slag

Studies have shown that nickel slag is a good aggregate for the synthesis of inorganic polymers. Under suitable conditions, it can even produce a cementitious material with compact internal structure, extremely low water absorption, and compressive strength of up to 118MPa. To meet these conditions, the nickel slag vertical roller mill is indispensable. Nickel slag vertical mill is a combination of fine crushing, grinding, drying, powder selection and conveying. It can grind nickel slag into powder, and its specific surface area can reach 480-500㎡/kg to ensure that the activity of nickel slag is fully exerted. Studies have shown that nickel slag powder can be added to cement clinker. According to the national standard, the addition amount can reach 8%, and the nickel slag has pozzolanic activity, and the addition amount of cement can reach 30%. Experts in the industry have done many research experiments. The results show that nickel slag can produce clinker cement, and nickel slag has very good activity, which is slightly better than steel slag.
