Air Jet Mills

Opposed Jet Mills are a type of air microniser used for the superfine grinding of a wide range of specialist materials when other forms of grinders are unsuitable, particularly in cases where the feed material is hard, already relatively fine, has a low melting point or where high purity products, without contamination, are required. Material is ground by attrition by introducing compressed gas, accelerated to sonic velocity through a series of nozzles, and an integral rotary classifier wheel ensures only fine milled product leaves the system. This single unit is capable of milling materials up to a hardness of 10 Mohs and it enables accurate and highly controllable product sizes to be achieved with sharp cut-off and a typically narrow size distribution. The Opposed Jet Mill range of equipment is widely used for reducing particle size in the chemicals, metal powders, minerals and plastics industries.
