Blast furnace slag is a by-product of blast furnace ironmaking of steel mills. After being quenched by water quenching, it is light gray glass crystal grain and belongs to industrial waste material. Has long been directly used as a cement mixture, because the slag than the cement clinker is easy to wear, in the ordinary cement grinding slag after the particle size than you sleep a lot of rough, slag activity is not fully play, Granular slag in the cement hydration process only play the role of micro-aggregate filling. In recent years, after a large number of detailed experimental study, the slag grinding into a high specific volume, high fineness, so that it has become a potential gelling material may have become a display, its activity in alkaline conditions Get full play, so that the concrete and cement multi-directional performance has been greatly improved and improved.
How to determine the process design:
Design Overview: As the water quenching slag with high water content, easy to wear and so on, the characteristics of separate grinding slag powder is more difficult, has been in low yield, high power consumption, into the slag water is difficult to remove the state. In recent years, with the efficient energy-saving drying technology, high-quality high-yield observation equipment research and development, making high-fineness, high specific volume of slag powder industrial production has become possible, Chaeng use the mature technology and equipment has been designed and put into production Hundreds of slag powder production line, the formation of low-cost economic process design.
Slag powder production line process:
Stacked slag through the automatic feeding system, through the belt conveyor. In the transport process, the slag raw materials have been through the separator and shaker to get iron and sieve, and then through the weighing equipment warehouse, the elevator into the vertical mill for grinding. After the grinding of slag with hot air furnace to provide hot air, through the separator for powder, while drying. Meet the fineness of the requirements of the slag powder was finally transported to the collector collection, in full bloom, by the air transport chute, the elevator into the finished product storage.
Why is the choice of vertical mill slag grinding? Energy saving, environmental protection, simple process, a high degree of intelligence
In recent years, slag vertical mill application more and more recognized by the majority of customers, but some customers still over the mill is better than the ball mill doubt, Chaeng( Great Wall Machinery) through visits to dozens of customers on-site, sort out the two systems the difference.
In summary: vertical mill system in the process, energy saving, environmental protection and post-maintenance has an unparalleled advantage!
