systems are used for deaerating and compacting, i.e. increasing the bulk weight of powders smaller than 40 µm.
The VACUPRESS can handle product temperatures up to approx. 100 °C. Densification of the product is particularly gentle. Compared with conventional compactors or granulators, the pressing forces applied in the VACUPRESS are relatively low and thus only have a minimal impact on the characteristics of the treated products. The product flakes and slivers produced can be converted back to their original fine powdered state at any time without having to apply strong shearing forces. Reductions in volume of up to 75 % are achieved. The machine can usually be used for bulk weights below 750 kg/m³.
