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 blast-furnace slag powder grinder:
There are five types of Shanghai CLIRIK Ground granulated blast-furnace slag powder grinder, they are HGM80, HGM90, HGM100, HGM100A and HGM125. The finished production fineness can be reached 300meshes~3000meshes, 5-47 micron. The capacity (ton/hour) ranges from 0.4T/H to 12T/H.
Industrial use of ground granulated blast-furnace slag powder:
Ground-granulated blast-furnace slag (GGBS or GGBFS) is used to make durable concrete structures in combination with ordinary portland cement and/or other pozzolanic materials. GGBS has been widely used in Europe, and increasingly in the United States and in Asia (particularly in Japan and Singapore) for its superiority in concrete durability, extending the lifespan of buildings from fifty years to a hundred years.
Features of Ground granulated blast-furnace slag powder grinder:
1. Ground granulated blast-furnace slag powder grinder is high efficient (twice as much as jet mill, mixing grinder and ball mill)
2. The spare parts of Ground granulated blast-furnace slag powder grinder can serve much longer time (2-3 times longer than that of impact mill or turbo mill.
3. High safety and reliability of rolling bearings and screws in the grinding cavity, so no problems caused by the wear of bearings or screws)
4. Ground granulated blast-furnace slag powder grinder is characterized by high fineness (final size: 325-3000 mesh, D97<5 micron)
5. Environment-friendly.

Features and advantages of Ground granulated blast-furnace slag powder grinder:
● High Efficiency
Under the same finished final size and the same motor power, the capacity of powder grinder machine is twice as much as jet mill, mixing grinder and ball mill, and energy consumption decreased 30%.
● Long lifecycle of spare parts
The ring and roller are forged by special material with high utilization. Under the same grinding material and finish special size, the lifecycle of spare parts is about one year, which is 2-3 times longer than impact mill or turbo mill. Furthermore, the lifetime can reach 2-5 years for grinding calcite carbonate.
● High safety and reliability
As no rolling bearings or screws in grinding cavity, there are no problems caused by bolts shedding or rapid wear of bearings and seal components.
● High fineness, flexible adjustment
The final fineness of the grinding materials can be adjusted between 325 meshes and 2500 mesh (47-5 micron), and the product fineness can reach D97≤5μm.
●Environment-friendly
The application of pulse bag filter and muffler greatly alleviates dust pollution and noise.
●Advanced intelligent speed control device
Convenient adjusting, more uniform particle size.
