Spiral Jet Mill Classifier For Grinding Classification

Aerodynamic classification in a spiral jet mill ...

01/07/2013  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. The size reduction ...

Aerodynamic classification in a spiral jet mill ...

In a classical jet-mill, the particles that are forced by air into a circular motion are colliding with other particles as well as with the walls. Such collisions might break the particles thereby reducing the particle size. The air enters the mill at the periphery and exits at the center. The centrifugal and the drag forces are acting simultaneously on each particle in the grinding chamber ...

The spiral jet mill cut size equation - ScienceDirect

01/10/2016  Many spiral jet mills have a classifier that results in a different gap size for gas flow at the grind chamber exit compared to the rest of the grind chamber. The purpose of the classifier is to prevent the escape of larger particles which can travel along the walls of the grind chamber where the radial velocity is higher and radial drag dominates over centrifugal forces. In this case, a flat ...
