Slag is the main solid waste produced in black metallurgical industry. There is little hydraulicity when slag exists alone. But slag will show the hydraulicity when it suffered excitation force, and we will get superfine powder when blast furnace slag is ground. Slag powder can be used as cast stone, glass ceramics, fertilizer, enamel, ceramics, etc. raw materials, so slag powder has been more and more popular.
The working principle of slag powder production line is as follow.
Firstly, slag will be sent to slag heap for storage by discharge hopper and belt conveyor.
Secondly, forklift will send materials to feed hopper and then they will go to quantitative feeder for metered. Belt conveyor with electromagnetic iron remover will send them to the feeding outlet of slag vertical mill.
Thirdly, hot air stove installed in front of slag vertical mill will provide the heat source required by grinding and drying process.
Finally, slag powder after dried will be collected by pulse dust collector. And air conveying chute and elevator will send finished products to slag powder silo.
