Abstract:In order to increase the lumpy rate of leadzinc sintering, a new kind of high effective binder L was screened from eighteen kinds of binder, which is an organic binder raising the strength of granule. The results of industrial application showed that, when 0.0594% L is added into mixed mineral, the sintering lumpy rate can be raised by 16.17% and the hourly output of blast roaster beincreased by 11.6%. It makes remarkable economic effects.
