### ConJet High Density Bed Jet Mill - NETZSCH

The high-density bed jet mill represents an advanced development of the spiral jet mill. Its core feature is the integration of a dynamic air classifier at the centre of the grinding chamber. This enables optimal independent setting of the grinding fineness and efficiency. In addition, the circular motion of the material ground in the grinding chamber and the air classifier restricting product

Grinding improves pellet quality by reducing air spaces between particles, allowing closer surface to surface contact for a given volume of feed; i.e., it increases bulk density. Large pieces of any ingredient in a feed formula result in weak spots in the pellet, especially if these are fibrous or bony. Grinding also increases the total surface area of a given weight of feed, thereby allowing
