Shear Gap Granulation

Researchers at Purdue University have developed a mixer-granulator system, termed the Shear Gap Granulator (SGG), that granulates fine powders and a binder liquid into granules. Current granulation methods are difficult to scale and control when making granules with desired structures and narrow size distributions. SGG instead uses a modular design to rapidly test formulations at varying batch sizes while offering easy customization and cleaning. Purdue's approach can also be extended to use in continuous production. This technology has applications across a wide range of industries, including agriculture, pharmaceuticals, chemicals, and building materials.
