The PerMix High Speed Mixers, also called High Speed Granulators, Wet Granulator, or High Shear Mixer Granulator, is an efficient and versatile blending machine for mixing of dry powders, or granulating with the addition of liquid binder, within a very short time and with excellent cleaning abilities.
It is able to give perfect result for mixing due to the innovative design of a central impeller type mixer with a side vertical Chopper.
PerMix High Speed Granulators consist of two electrical motors, one reduction gear, coupling, and shafts with the two agitators. The shaft is sealed with special sealing, sometimes with air purge, in a way that there is limited contact between the material and the seal. Materials are loaded from top side, and the discharge is located at the bottom side.
Due to the consistent modular design, the High speed granulator can be configured individually and easily adapted to the constructional circumstances and specific requirements.
In a permix pdi series high speed granulator, the powders are set in a multidimensional shear flow state and it needs only short mixing time until they are thoroughly mixed. In case that granulation is required, the spraying system sprays the binder solution into the bowl to agglutinate with the materials and under the combined action of the impeller and chopper, uniform and porous granules are produced.
After finishing the mixing or granulation process, powders/granules are discharged through the side discharge with no “dead zone” valve.
