Rotor fine granulators RFG 250 D/ DL/ DDL

Rotor fine granulators for the pharmaceutical, chemical and primary industry

The rotor fine granulators of the type 250 are designed to meet the requirements and standards in the pharmaceutical, chemical and primary industry and are made for granulation of dry or slightly moist substances.

With these three models Alexanderwerk offers a staged range of powerful machines, which can achieve a throughput of up to 4,500 kg/h, depending on the chosen raw material and screen basket. Screen baskets with mesh sizes from 0.63 mm to 3.15 mm are available to achieve different granule geometries.

In comparison Alexanderwerk has developed a patented granulator in Diagonal-Design®, which raises the capacity up to 100 % by increasing the effectiveness of the working area of the screen. This leads to a doubling of throughput and in turn to a very gentle granulation with minimal fines generation. Additionally production costs are reduced and the quality of the final product is increased. In addition, the mobile design provides great flexibility during compaction and allows an easy maintenance.
