Air Jet Sieving Machine AS 200 jet
The new Air Jet Sieve AS 200 jet is particularly suitable for light materials with particle sizes in the lower micron range. It is used with sieves of 10 microns mesh size or more. The procedure is very gentle on the material as no mechanical sieving aids are required. The average sieving time is 2-3 minutes.
Application Examples
ceramics, chemical products, cosmetics, food, minerals, pharmaceutical materials, pigments, plastics, powder coating, rubber, toner, washing powder, ...

Function Principle
The AS 200 jet is equipped with a rotating slotted nozzle. The sieve and lid are placed above the nozzle. A vacuum generates a strong jet of air which disperses the particles on the sieve through the slotted nozzle. The material which is smaller than the mesh size of the sieve is transported by the back flow of the air to the cyclone or to the vacuum cleaner. The air jet helps to deagglomerate the particles and constantly purges the sieve mesh.
