DIOSNA HIGH SHEAR
GRANULATORS
 |
High Shear Granulating is a highly effective method of
producing a uniform dense granule. The machine's function is simple in principle. Dry powders
are first loaded into the granulator by vacuum or gravity.
The Diosna granulators are extremely quick and efficient mixers
of dry powders. Dry mixing is the first step of the process. After the products are mixed by
means of our unique, bottom drive rotating tool (impeller), a binder is
introduced into the product. The binder can be added in dry form or sprayed in as part of a
binding solution. Spraying occurs though one or more spray nozzles and is quickly dispersed
into the product by the mixing action of the main mixing tool (impeller) and the chopper
blade. The chopper blade, which is positioned in the highest circumferential area of the
product aids in de-lumping. Once all of the solution is in the granulator, the impeller and
chopper work together during the wet massing phase to produce dense granules of uniform
particle size. The system quickly forms granules that are then easily and
automatically discharged from a port in the bowl's side. The wet granules are generally
milled as they come out of the granulator. The granules then need to be dried such as in a
DIOSNA Fluid Bed Dryer machine (see fluid beds).
