The mill Rotodue 4C is suitable to produce air classified powders with granulometry in the range 0 to 100÷300 micron, with d50= in the range 10÷40 micron.
Product fineness is easily adjustable by varying the speed of the dynamic air classifier.

The discharge of the product is pneumatic in air stream and therefore the mill is specially suitable for the operation with hot gases.

This allows a partial drying of moist materials during the grinding operation and results in a tremendous reduction of investment, space and operation costs compared with plants where drying is made in separate equipment before grinding


Drying and grinding of petroleum coke and/or coal 97% minus 90 micron, for plants using solid fuel.

Fine grinding and drying of clays for single-fired ceramic tiles

Production of fine powders of medium hard minerals, such as talcum, gypsum, limestone, barite, lime, magnesium oxide.
