Water slag superfine powder roller mill, efficient treatment of water slag

The large-scale exploitation of natural resources in the industrial field not only caused the reduction of non-renewable resources, but also caused a large amount of solid waste to accumulate. Using water slag superfine powder roller mill to grind water slag superfine powder instead of cement to make building materials which can solves the problem of solid waste accumulation, and it can produce high value-added building materials - aerated concrete blocks, which requires to use the water slag superfine powder roller mill.

Some Chinese scholars have used water slag superfine powder instead of cement to make aerated concrete building materials through experiments. The aerated concrete block product is a kind of cementitious material containing silicon, calcium, sulfur, aluminum, etc. as the main raw material, with aluminum powder as the air-generating agent, supplemented by other regulators. Made by steaming. Its structure is composed of small pores that are not connected to each other and mineral crystallites mainly composed of calcium silicate, it has good thermal insulation properties. The advantages of aerated concrete is it’s light weight, earthquake resistance, convenient construction, etc., good machinability, can be sawed, planed, drilled, and nailed. Air-entrained concrete blocks are suitable for internal and external filling walls of frame structures, roof insulation materials, and are especially suitable for adding floors to old buildings. It can be used for load-bearing structural walls of low-rise buildings.

Air-entrained concrete and air-entrained concrete blocks are made of calcareous materials (such as cement, lime) and siliceous materials (such as sand, fly ash, slag) and aluminum powder is added as an air-entraining agent. Porous silicate blocks formed, gas-expanded, pre-cured and cut, and then cured by high-pressure steam. The cost of using traditional cement quicklime-cement raw materials is high, and it will be restricted by environmental protection policies when attacking. Therefore, superfine powder of slag can be used instead of cement.

Water slag superfine powder is a substance that is ground with water slag superfine powder roller mill after high-temperature water quenching in the ironmaking process of ironworks. It has high activity and can be mixed with powder under certain alkalinity and temperature conditions. The coal ash siliceous material undergoes a hydration reaction to increase the strength of the product.

Guilin Hongcheng water slag superfine powder roller mill grinds water slag superfine powder with excellent quality. Water slag raw materials are crushed, milled, sorted, collected and other processes to obtain water slag superfine powder, which can replace cementing materials High value-added building materials. Guilin Hongcheng HLM series vertical mill is suitable for milling water slag superfine powder and can be used as water slag superfine powder roller mill.
