With the Vibratory Sieve Shaker AS 450 control RETSCH have designed their first 3-D shaker for 400 mm and 450 mm sieves. It can be used for dry and wet sieving of sample amounts of up to 25 kg. The AS 450 control combines the benefits of electromagnetic sieving – controlled amplitude with highest reproducibility – with the powerful drive based on CET technology (Continuous Energy Transfer).
Even with high loads a constant vibration height of 2.2 mm and, as a result, high separation efficiency are achieved thanks to the continuous controlled energy input. Manual re-sieving is no longer required. When it comes to operating comfort, the AS 450 control meets all the requirements of a modern laboratory. All parameters such as amplitude, time and interval are digitally set, displayed and controlled via a remote operation panel
There are many applications for which wet sieving is the best solution, e.g. when the material to be tested is a suspension or when a very fine sample (< 45 μm) that tends to agglomerate needs to be sieved. All vibratory sieve shakers from RETSCH can be used for wet sieving. There are special accessories like clamping lids with spray nozzle and collecting pans with outlet available. By placing RETSCH’s venting rings between the sieves, air cushions can expand without letting liquid or sample material escape.
RETSCH's vibratory sieve shakers are ideally suited for separation, fractioning and particle size determination of cement clinker, chemicals, coal, coke, construction materials, fillers, minerals, ores, plastics, sand and soils.
With the RETSCH clamping devices the sieves are clamped safely, quickly and conveniently on the sieve shaker. The clamping devices “comfort” are particularly user-friendly and timesaving.
Collecting pans, intermediate pans, intermediate rings and sieve lids.
Clamping lid with nozzle, collecting pans with outlet, venting rings.
Chain rings, brushes, cubes, balls (e.g. for reducing agglomerations when sieving particles < 100 μm and keeping the mesh free).
We provide IQ/OQ documentation for the „control“ sieve shakers to support IQ/OQ certification by our customers.
Suitable for thorough cleaning of test sieves and for quick, gentle drying of samples and sieves.
EasySieve, the software for particle size analyses, exceeds manual evaluation in many aspects. The software is able to automatically control the necessary measurement and weighing procedures – from the registration of the weight of the sieve up to the evaluation of the data. It is simple and convenient to use and is also available in an FDA 21 CFR Part 11-conform version.

Siktemaskinen AS 450 control har et elektromagnetisk drivverk som RETSCH har patent på (EP 0642844). Dette drivverket sørger for en tredimensjonal kastebevegelse som får siktematerialet til å bevege seg jevnt over hele sikteflaten. Fordelene med dette er høy kapasitet, ekstremt, rolig kjøring og kort siktetid med høy separasjonsgrad.
