Jet Mill Manufacturers

Jet mills are used for very fine grinding of hard or medium hard, temperature sensitive particles. In jet mills, particles of feed collide, as air sweeps them along. Three basic variations are the counter jet mill, the spiral jet mill, and the oval jet mixer. In the counter jet mill, particles are ground as two air jets containing them, impact when they meet. Both jets flow on the same axis at the same velocity but in opposite direction. In the spiral jet mill, the product is injected, by means of compressed air in high-speed air stream, rotating in a circular channel. Size reduction is achieved through intensive attrition among particles. The oval jet mixer consists of an oval channel in which air and particle circulate. The incoming particles are size-reduced by the pressurized air stream at the lower part of the channel and collisions with each other. The main advantage of jet mill is contaminant free processing.
