For Hazardous Environments

Acupress Deaerating and Compacting Systems

06.05.2015 Vacupress systems from Grenzebach are used for deaerating and compacting, i.e. increasing the bulk weight of powders smaller than 40 µm. The newly developed Atex design can now also be operated in hazardous environments.

Acupress Deaerating and Compacting Systems

Compared with conventional compactors or granulators, the pressing forces applied in the new system are relatively low and thus only have a minimal impact on the characteristics of the treated products (Picture: Grenzebach)

The system 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 new system are relatively low and thus have only 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.
Due to the reduction in volume which results from a higher bulk density, the products can be incorporated faster and easier. This is an advantage for new investments in which, e.g., a smaller machine (extruder) can be avoided. For existing plants, the use of the system can increase the performance of extruders or packaging machines up to 50 %. Dosing of products with higher bulk density can be made more accurate with the help of a differential weighing machine. Generally the soft compaction barely effects the characteristic of the product.
