Slag introduction:

Slag is a by-product of the blast furnace ironmaking process. It is the reaction of silica, alumina and other impurities with lime to form a melt with silicate and aluminosilicate as the main components, which is quenched into a loose and porous granular material, which we call blast furnace slag.

From a production point of view, slag powder is the abbreviation of granulated blast furnace slag powder; from a physical point of view, slag powder is a granular slag powder material processed by slag through certain equipment; slag powder is a high-quality concrete participating compound powder; Therefore, with the continuous increase of the scale of industrial production in China, the discharge of slag has also increased a lot; based on the industrial application of slag powder, the promotion of recycling of slag resources has also opened up its application market;

Selection of slag grinding equipment:

The grinding technologies for ceramic production include two kinds --- production by dry-process and by wet-process. The latter is common. Wet-process Production Line Ball mill + drier: The raw material is sent to the ball mill and ground to be slurry by adding 30-40% water. Then the slurry is dried by drying tower with water content controlled at 7%. But this method features long drying time and low yielding.

Dry-process Production Line Vertical mill (or T-typed mill)+pelletizer:The material is sent to the mill directly. And then the pelletizer works to add moisture of material. After that, the fluidized bed dries the powder and the water content would be controlled at 7%. Finally, the technology of grinding by pressure is taken. But this method features short drying time and high yielding.
