Introduction

Water slag is formed by rapidly cooling molten blast furnace slag in water, mainly by water quenching in slag pool and water quenching in front of furnace. Blast furnace slag is a kind of molten material, mainly composed of calcium silicate and calcium aluminate, which is produced in the process of pig iron smelting by blast furnace. It is granulated by water quenching. It is referred to as water slag, water quenched slag and so on. When the furnace temperature reaches 1400-1600℃, the burden melts, gangue in ore, ash in coke, cosolvent and other impurities which can not enter pig iron form slag mainly composed of silicate and aluminate, whose main components are CaO, SiO₂ and Al₂O₃.

Water slag Processing technology

Water slag is the hot melt blast furnace slag in the water after rapid cooling of the waste slag, used to be abandoned, or is used to fill the road, and now through the blast furnace water slag grinding machine processing, the resulting water slag powder can be used as concrete and cement raw materials. Slag has potential hydraulic cementing property. It can be used as high quality cement raw material by using water slag micro-grinding machine, and then under the action of cement clinker, lime, gypsum and other activators. The blast furnace slag mill manufactured in Vanguard can process the slag to 325 mesh fine powder, which is beneficial to its application. Vanguard provides users with a complete set of slag powder production process, including the drying of water containing slag for drying treatment, crusher of crushing large slag, slag mill, conveyor hoist and other equipment. Vanguard Slag Mill is a vertical structure, covers a small area, complete sets of strong, and the main engine transmission device using closed gear box, stable transmission. The important parts of the mill are made of high-quality steel, so the whole mill is wear-resistant and reliable. The mill adopts centralized control, advanced and reasonable selection and high degree of automation. The vibrating feeder is small and light in weight, easy to adjust and maintain, and saves electricity very much.
Slag is used as building material for cement and concrete. Because of its potential hydraulic cementing property, it can be used as high-quality cement raw material under the action of cement clinker, lime, gypsum and other activators. It can be made into slag Portland cement, gypsum slag cement, lime slag cement, slag brick, slag concrete and so on. It can also be used as a raw material for producing environmental friendly cement bricks.

Application fields Through the deep processing, Water slag can be widely used in the following industries.
