Wet granulator operating according to the oscillating rotor principle.


Wet Granulator

The WG-30 Wet Granulator operates according to the oscillating rotor principle by compressing the wetted mass through a stainless steel sieve of a predetermined size. Later on, the formed granules can be collected, dried and, if necessary, dry-crushed. The WG-30 Wet Granulator is designed for the production of granulates in various sizes from wetted powders as a feed. It can also be used to reduce dry masses or for re-processing of rejected tablets using sieves with big openings.

Operation Mode

Two knurled screws are built in to allow the operator to apply equal tension to all zones of the sieve during contact with the oscillating rotor. The high quality stainless steel oscillating rotor has 4 blades. The rotor may be readily removed for cleaning using the two handwheels in the front of the apparatus.

The oscillating rotor has an oscillation angle of 90°.The WG-30 Wet Granulator is provided with two standard sieves: d = 1.0 mm and 1.6 mm respectively.  Other sieves with different sizes are also available as an extra option and they are readily interchangeable through the user friendly design.

The WG-30 Wet Granulator can be directly attached to the UAM Universal Motor Drive, which offers a smooth stepless speed adjustment. All contact parts are made of GMP Compliant materials and can be sterilized in accordance with GMP.
