Product Details
Slag is a vitreous material formed when molten slag from blast furnace ironmaking is rapidly cooled without having time to crystallize. After being finely ground, slag becomes an active blending material for cement.
The Slag Vertical Roller Mil integrates grinding, drying, powder selection, conveying, and collection into one system. With a rational overall structure, professional technology, simple control, easy operation, stable and reliable performance, and convenient maintenance, its main technical and economic indicators have reached an advanced professional level.

Working Principle
The slag material is fed to the center of the grinding table through the feeding pipe. The grinding table rotates at a constant speed, and under the action of centrifugal force, the raw material is uniformly dispersed and spread outward, forming a material bed of a certain thickness. The slag material is simultaneously crushed by the rolling of multiple grinding rollers on the table.
Driven by continuous centrifugal force, the slag material moves toward the outer edge of the grinding table. As the material leaves the table, it encounters hot gas entering the mill through the wind ring, rising with it. The material then passes through the central casing of the mill into the powder separator. During this process, the fine slag powder material fully exchanges heat with the hot gas, resulting in rapid evaporation of moisture.
The powder separator controls the fineness of the product at the roller mill’s outlet. Particles larger than the specified size are separated and fall back onto the grinding table, while materials meeting the fineness requirements pass through the powder separator and enter the finished product silo.
Features
1.Low energy consumption, low wear and tear, long service life.
2.Large output, high grinding efficiency, high powder selection accuracy.
3.Low dust and noise pollution, strong drying capacity.
Applications of Slag Vertical Roller Mill
Slag vertical roller mills are widely used in cement plants and slag micro-powder production lines to convert blast furnace slag into high-value GGBS. The finished slag powder is used as an active admixture in cement and concrete, improving durability and reducing production cost. Our mills also grind other industrial by-products such as steel slag, nickel slag and clinker when required.
How to Select a Slag Vertical Roller Mill
Select the GRMS model according to your annual GGBS output target and available power supply. For output below 30 ten-thousand tons per year choose GRMS33; for 30-45 ten-thousand tons choose GRMS40; for larger plants choose GRMS46, GRMS53 or GRMS56. Our engineers provide complete plant design, including the slag conveying, drying gas and finished product storage systems, to match your site conditions.
