Main advantages of "Huawei" bentonite for Metallurgy:
1)The bentonite binder used in metallurgy pellet binder for iron ore pellet, in a variety of fine iron ore sand bond pellets.
2)It can obviously increase raw pellet strength and ruptures temperature to expand roasting area, the permeability of raw material layer is good, and improved pellet quality, reduce costings.
3)Can obviously increase the economic efficiency of Iron and steel enterprises.
4)Has the additive amount is few, drop strength high, compressive strength high, anti-to rupture and so on merits.
In recent years, bentonite for Metallurgy pellet is the essential raw materials when iron fine powder nodulizing.
Sodium bentonite as binder, has iron fine powder into a ball group rate, drop the number of times, compressive strength, rupture temperature etc. other index is much higher than ordinary. Especially it reduces immensely return mine rate.
