The leadzinc ore from the mine at Mount Isa has become more difficult to treat in recent years. Efforts to restore performance in the LeadZinc concentrator led to the doubling of the total grinding capacity. A KW700F Tower mill was installed in the LGM circuit (Figure 2) during 1991 as a part of this effort.
Mechanical properties and particle size composition of a leadzinc ore in Yunnan were determined, and the problems such as low processing capacity of a section ball mill, substandard fineness and unreasonable particle size composition were solved through the contrast test of grinding medium. The experimental results show that the ore is medium hard and soft ore, with uneven distribution, and ...
The present literature review explores the energyefficient ultrafine grinding of particles using stirred mills. The review provides an overview of the different techniques for size reduction and the impact of energy requirements on the choice of stirred mills. It also discusses the factors, including the design, operating parameters, and feed material properties, influencing the grinding ...

In the 1950s and 1960s ball mills dominated primary grinding, however they were supplanted in the 1970s by AG and SAG mill which also replaced two stages of crushing. Nowadays ball mills still dominate secondary grinding applications, but are increasingly in competition with closed circuit AG/SAG mill circuits and stirred mills .
