Rapid Mixer Granulator

The Rapid Mixer Granulator operates on the principle of high-shear wet granulation, combining mixing and milling in one bowl through mechanical agitation. The process relies on rising, whirling, and tumbling motions induced by the impeller and chopper. Here’s a step-by-step overview:

• Dry Mixing: Powders are loaded into the bowl. The impeller runs at low to medium speed for 3-5 minutes to achieve uniform blending without granulation.

• Wet Mixing (Binder Addition): A liquid binder is sprayed or poured in while the impeller continues at a higher speed. This wets the powder, forming a soft mass.

• Granulation: The chopper activates at high speed for 5-10 minutes, shearing the wet mass into uniform granules. The impeller aids in fluidizing the material to prevent clumping.

• Discharge: Granules are expelled through the bottom port via pneumatic operation, ensuring complete emptying at a 45-degree angle for efficiency.

Rapid Mixer Granulator working principles are based on two decisive factors essential for the intimate mixing system.

• Spinning close to bottom of mixing bowl.

• The impeller sets the entire mixture in whirling rising.

Tumbling motion ensuring a quick & even distribution of all dry components. This leads to an even distribution of all dry components & an even wetting of every granule. The large lumps occurred during wet mixing are broken up, by the strategically acted chopping tool rotating at 1440/2880 RPM.

The mixture can be discharged with the impeller running through outlet located on the side of the mixing bowl flush to the bottom. Easy accessibility for cleaning is guaranteed by the low profile. The mixing tool is easily removed from the drive shaft providing an unobstructed mixing area which may be cleaned very easily.
