Micronisation Services

Lab Service S.A. offers a wide range of services which includes micronisation services. Features: it consists of projecting powder particles against each other using converging air jets. The impact between these particles causes them to break up into smaller ones. The microniser is basically a flat cylindrical casing with tangentially oriented inlets around the outside, through which compressed air is injected. When powder is introduced into the microniser through the milling device, the particles are propelled by the venturi effect of the air jets, collide and break up. The air jets induce a circular movement of particle-charged air. The centrifugal force causes the larger particles to return to the grinding zone. Once the remaining particles have reached the correct size, they are concentrated in the centre of the microniser and are pumped out through a central duct. It makes it possible to obtain an average particle size of between 1 and 30 µm.
