Abstract 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. These forces define classification phenomenon between finer and coarser particles. For fine… CONTINUE READING
