Ground-granulated blast-furnace slag (GGBS or GGBFS) is obtained by quenching molten iron slag (a by-product of iron and steel-making) from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine powder. Ground granulated slag is often used in concrete in combination with Portland cement as part of a blended cement.
GGBS is a new type and highperformance concrete admixtureas for cement manufacturing. Our company is a professional slag powder production line supplier, which providing the entire technical solutions and equipment of 10, 30, 50, 80, 100, 150, 200 thousand tons annual capacity.
1. Comprehensive Service: We are a professional slag powder production line supplier. We can provide both ball mill and vertical mill production process, while providing 'turnkey' service from civil engineering to commissioning.
2. Serious Quality Control: We have a strong capacity of manufacturing and could control product quality seriously with short delivery time. Expert Installation and After-service Team could ensure to finish plant installation and start running on time.
3. Low Investment Cost: Slag Vertical Mill Production Line from ZKCorp engages the advantages of simple process flow, high-efficiency of grinding, great drying capacity, efficient Powder-classifying, easily-adjustable outputting size, low noise and electricity-consumption, small mill consumption, high degree of automation, low running expense, which make it suitable for small and middle plant owner.
Production Process by Vertical Mill: Slag is transported into the plant by truck and stored under the shed. After reclaiming by loader and metering by feeder, the material is delivered and de-ironed into the vertical mill by the belt conveyor and its magnetic separator.
After deironing the slag enter the vertical mill for grinding. Dried and grinded slag powder is collected by the separator and sent into the finished product silo by air chute and bucket elevator. The discharged slag is sent back to the mill by conveyor and elevator. The drying heat source is provided by an air heating furnace.
Production Process by Ball Mill: Slag is transported into the plant by truck and stored under the shed. After reclaiming by loader and metering by feeder, the material is delivered into the dryer by belt conveyor for drying. After drying the slag enter the ball mill for grinding. Grinded slag powder is send into the separator by the bucket elevator for grading. Qualified power is sent into the finished product silo by air chute, hoist and elevator. Large particle powders return to ball mill for regrinding. There is the dust filter at the discharge end of the ball mill. The slag dust is collected and transported into the finished product silo. The drying heat source is provided by an air heating furnace.
