Granumeist High Shear Granulation
The Granumeist High Shear Granulator/Mixer system is designed for efficient and homogeneous wet granulation of powders to form medium to high density granules with excellent flow and compression characteristics. The granulation process is very quick and is usually transferred into a VFC Flo-Coater fluid bed for drying. There are two styles of Granumeist granulators. Both styles produce equivalent granulation processes. There are non-processing advantages associated with both designs, which are discussed below.
Top Drive: “GMX”
The top drive GMX system has the mixer and chopper enter through the top lid. The bowl is lifted up to the blade for processing. Advantages include the ability for the bowl to be removed for cleaning inspection. Also, the seals for the mixer and chopper are removed from the processing area.
Bottom Drive: GMXB
The bottom drive GMXB system has the mixer blade enter the bottom of the process bowl. The chopper is mounted through the side. The bottom drive system is the more widely used type of high shear granulation system. It has an advantage in larger batch sizes (1800L versus 1200L max capacity for top drive systems) and can process up to 90% of the bowl rating (versus ~70% for top drive systems).
