Rotor fine granulator RFG 150 DS

Rotor fine granulators for the pharmaceutical, chemical and primary industry

The RFG 150 DS is designed by Alexanderwerk to meet the requirements and standards in the pharmaceutical, chemical and primary industry and is made for granulation of dry or slightly moist substances.

Depending on the raw material and screen basket, the throughput can be as high as 600 kg/h. 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 with minimal fines generation.
