This series screen is always used in processing minerals such as ferrous metals including hematite magnet and nonferrous metals including lead, zinc, gold and silver, etc.
The disk grain making machine is suitable for the mixing ball equipment of the nutrient content is 10-30%.
The high-efficiency concentrator produced by our company is suitable for dehydrating the ore concentration and tailings.
Flotation machine (also called flotation separator) is applicable for the separation of nonferrous metal and ferrous metal and nonmetal, such as fluorite and talc.
Stirring tank is suitable for mixing before flotation, for various metal and ores to adequately mix pharmaceutical and pulp, and it can also be used for mixing other non-metallic minerals.
Efficient classification is particulary important in power station applications; a steep product particle characteristic curve ensures that optimum combustion is achieved in the boiler while keeping emission rates at a low level.Loesche dynamic classifiers can be fitted to any type of coal mill.
