Compaction, granulation, crushing and filling
System partner for compaction and granulation machines
Alexanderwerk's core area of expertise is related to mechanical processing of raw materials. This involves machines for particle size enlargement (e.g. roller compactors, moist granulation machines) or for particle crushing (e.g. rotor fine granulators, grater/shredders, toothed disc crushers).
Compaction in the pharmaceutical sector
The cantilevered rollers allow easy cleaning when changing products. Careful selection of the best materials ensures high acceptance of the systems in the GMP sector. In combination with the latest technology, these ingenious and proven systems ensure outstanding ease of use.

Grater/shredders
In order to satisfy the need for materials with a uniform particle size and shape among processors and manufacturers, Alexanderwerk offers grater/shredders for different requirements. The continuous process employed by the grater/shredder is suitable for dry, moist as well as solid base products.
Rotor fine granulation in Diagonal-Design®
An important element of machines from Alexanderwerk is their crushing technology involving granulation, grating, shredding and cutting.
Unlike conventional designs in which at least 50% of the crushing process takes place only within the working surface in the third quadrant, the effective working surface is significantly increased during granulation based on Diagonal-Design®. The rotor fine granulator increases the performance by up to 100%, and also produces more gentle crushing with less fine particles. This helps to minimise the investment costs and boost the quality of the finished product. Furthermore, the modular design allows fast changing and cleaning of all working tools and thus meets the prerequisites for flexible work.
Alexanderwerk's patented Diagonal-Design® delivers up to 100% higher throughput capacities compared to the conventional design.
Moist granulation machines
Moist granulation is a continuous technique for the processing of moist, paste-like raw materials into granules. Due to the defined particle size, granules can be processed much better than the raw product.
