Freund-Vector’s High Shear Bottom Driven Granulation System

Precise configuration of the bowl, mixer and chopper produce efficient and homogenous mixing of dry powders or, when followed by uniform wetting with a binding solution, the production of homogenous wet granules. The mixer impeller is designed to generate an aggressive homogenous three-dimensional product flow throughout the bowl. Narrow particle size distribution, ideal compressibility, excellent flowability, high mechanical strength and semi-spherical granulate are few of the physical characteristics of the final product.
