Spiral Jet Mill Classifier For Grinding Classification

Spiral Jet Mill Classifier For Grinding Classification

Aerodynamic classification in a spiral jet mill ...

2013-7-1  Theoretical background The grinding process consists of two basic operations: size reduction and classification. Within a spiral jet mill the size reduction and the classification are accomplished simultaneously in the same volume. Size reduction occurs mainly near the outer walls as a result of particle–wall and particle–particle collisions.
