ACCESSORIES
RETSCH sieve shakers can be equipped with a variety of accessories to meet a wide range of application requirements.
- Clamping units
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.
- Accessories for test sieves
Collecting pans, intermediate pans, intermediate rings and sieve lids.
- Accessories for wet sieving
Clamping lid with nozzle, collecting pans with outlet, venting rings.
- Sieving Aids
Chain rings, brushes, cubes, balls (e.g. for reducing agglomerations when sieving particles < 100 μm and keeping the mesh free).
- Sample Dividers
Meaningful results can only be obtained if the sample represents the original material. Sample dividers produce representative part samples, thus ensuring reproducibility of the analysis.
- Ultrasonic baths and dryers
Suitable for thorough cleaning of test sieves and for quick, gentle drying of samples and sieves.
EASYSIEVE / CFR EVALUATION SOFTWARE
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.
APPLICATION EXAMPLES
RETSCH’s vibratory sieve shakers are ideally suited for separation, fractioning and particle size determination of cement clinker, chemicals, coffee, construction materials, fertilizers, fillers, flours, grains, metals powders, minerals, nuts, plastics, sand, seeds, soils and washing powder.
FUNCTIONAL PRINCIPAL
In the AS 200 tap, mechanical action is applied to the test sieves in two dimensions. In addition to a horizontal circular motion with 280 oscillations, a vertical tapping motion with 150 taps per minute helps the particles to pass the sieve apertures. This combination of sieving motions simulates hand sieving. The number of oscillations and taps is independent of the power frequency which makes the sieving results of the AS 200 tap comparable world wide.
