Retsch’s line of sieve shakers is the most comprehensive offering with regards to sieving motions, measuring ranges and sieve diameters, thus covering virtually any bulk material – from agglomerating powders to solid rocks (Fig.). Lately, two new models have been added to the range. The new Air Jet Sieve AS 200 jet is particularly suitable for sieve cuts of powdered materials which require efficient dispersion and desagglomeration. The option to store up to 10 SOP (Standard Operation Procedures) and the automatic vacuum regulator (accessory) guarantee reproducible and meaningful results. Innovative features such as the Open Mesh function, the selection of the nozzle speed as well as optional use of standard 2” high test sieves perfects the new air jet technology. With the sieve shaker AS 450 control RETSCH have designed their first siever for 400 mm and 450 mm sieves which operates with a three-dimensional sieving motion. It can be used for dry and wet sieving. The optimized electromagnetic drive with Retsch’s CET Technology allows for amplitudes up to 2.2 mm even with maximum loads up to 25 kg. Retsch’s sieving line is completed by test sieves and the evaluation software EasySieve®.
