Pharmaceutical Dry Compacting Systems

Pharmaceutical and chemical remedies and preparations are administered in the form of solid dosage- In many cases the powder mixtures cannot be processed directly because of the poor handling properties of the powder. Segregation, partly filled press dies and inconsistent final product may result. To economically and gently process such powders into the final product, the powder should be transformed into granular material. This influences the materials physical properties such as particle size, distribution, hardness, bulk density and surface area. Unlike the powders from which they are formed, granular materials are characterized by significantly improved flowability and an increased density.

Patented Combi-Vent-Feeder® Technology provides Efficiency
With roller compactors, the raw material is generally fed through a feed screw system. Eventually, it is the fed mass flux that determines the efficiency of roller compactors. That is why, at Alexanderwerk, they have started optimizing their feed modules at an early stage. A significant result of this is the development of the patented feed system of the Combi-Vent-Feeder® design.
