Rotor fine granulator RFG 250 DDL

The Type 250 rotor fine granulators were designed by Alexanderwerk for use in the chemical, pharmaceutical, food, life science, and nuclear industries, where they are used for granulating and comminuting dry or slightly moist raw materials.

With these three types, Alexanderwerk offers a closely graduated range of high-performance machines that can process up to 4,500 kg/h of material, depending on the raw material and screen insert. Various screen inserts with mesh sizes between 0.63 mm and 3.15 mm are available as standard to achieve different granule sizes.

In contrast to conventional designs, where at least 50% of the comminution occurs only within the working area in the third quadrant, the effective working area is significantly increased in the Diagonal Design® granulation process. This results in up to a 100% increase in performance for the rotor fine granulators, as well as gentler and finer-particle-reduced grinding, leading to minimized investment costs and improved end-product quality. Furthermore, the modular design ensures quick and easy changing and cleaning of all working tools, thus fulfilling the requirements for flexible operation.

Numerous special versions and customer-specific adaptations are available upon request. Due to technical modifications and further developments, the machines may differ in detail from the models shown.
