Nowadays, with the rapid development of the grinding industry, the application of water slag mill is more and more extensive. Water slag is the process of rapidly cooling the hot-melt blast furnace slag in water, mainly including slag pool water quenching or furnace front water quenching. Now let's learn what fields the slag grinder is generally used in and what is its working principle?

As a building material, water slag is used to produce cement and concrete. Due to its potential hydraulic cementitious property, it can be used as high-quality cement raw materials under the action of cement clinker, lime, gypsum and other activators, and can be made into: slag Portland cement, gypsum slag cement, lime ore slag cement, slag brick, slag concrete, etc.

As the mineral admixture of concrete, water slag micro powder can replace cement in equal amount and be directly added into commercial concrete. According to the difference of activity and specific surface area, the performance of concrete mixed with water slag micro powder in a certain proportion can be significantly improved. Water slag grinding machine is generally used for grinding and processing of non-metallic minerals such as coal mine, cement, slag, gypsum, calcite, barite, fluorite, marble, etc. with Mohs hardness below grade 7 and humidity below 6%. The product performance is advanced.

At the initial stage of mixing, the water slag mill is easy to control the rheology of concrete, improve the fluidity of concrete, and have good pumping performance; Reduce hydration heat; Reduce the demand for cement in concrete and increase the later strength of concrete; Anti shrinkage, strong binding force with reinforcement.

Principle of water slag mill: under the pressure of grinding roller, the material is crushed by extrusion, grinding and shearing. At the same time, the hot air is uniformly sprayed upward from the air ring around the grinding disc at high speed. The milled materials are blown up by the high-speed air flow at the air ring. On the one hand, the coarse-grained materials are blown back to the grinding disc for re grinding. On the other hand, the suspended materials are dried. The fine powder is brought into the classifier by the hot air for classification. The qualified fine powder flows out of the mill with the air and is collected by the dust collection equipment.

The water slag mill is an equipment integrating crushing, drying, grinding, grading and transportation. It also covers a small area and can be arranged in the open air, greatly reducing the investment cost and construction cost.
