DOUBLE ROTOR HAMMER MILL TYPE “ROTODUE 4/C” WITH DYNAMIC CLASSIFIER
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, driven by a motovariator.
The discharge of the product is penumatic 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.
APPLICATIONS
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, bentonite, lime, magnesium, oxide, etc.
