Concentrate material particulate skewness, and after final ore grinding, product granularity requires superfine, so must use
Grinding process so that the material of defective granularity requirements again returns to ball mill after ball milling and re-starts ball milling；
2, tradition grinding flowsheet is when graded operation, by the dense solid content for 60-70% of the solid content of 30-40%,
Load regulation ratio between the situation of feed blocking during as easy as rolling off a log generation discharging, and two (or multiple) grinding sections
More difficult, all ore pulps want twice (or repeatedly) by classification, and therefore required classification area is relatively big, leads
Cause investment too high.
Therefore, differential grinding process and flow sheet equipment scientifically and rationally is needed to be easy to the zinc of oxygen leaching technique
The process of concentrate raw material.
