SIEVE SHAKERS

AS 200.
Tap Sieve Shaker.

The AS 200 tap is suitable for dry sieving with test sieves of 200 mm or 8“ diameter. The combination of horizontal, circular sieving motions with vertical taps reproduces the principle of hand sieving. The uniform mechanical action ensures reliable and reproducible measurement results.

THE PRODUCT IN FOCUS

Model overview

The AS 200 tap is suitable for dry sieving with test sieves of 200 mm or 8“ diameter. The combination of horizontal, circular sieving motions with vertical taps reproduces the principle of hand sieving. The uniform mechanical action ensures reliable and reproducible measurement results.

This special type of sieving motion used by the AS 200 tap is specified in various standards for particle size analysis of materials such as activated carbon, diamonds, spices, metal powders, abrasives or cement. Operating the AS 200 tap is exceptionally easy and safe. The integrated clamping device allows for sieve stacks with up to 7 or 13 fractions, depending on the height of the sieve frame. The sieving time is set from 1 to 99 minutes via a digital display. The number of rotations and taps is fixed; the tapping motion can be deactivated, if required. A safety switch and an anti-trap protection provide maximum safety. Thanks to an integrated interface, the AS 200 tap can be controlled with the evaluation software EasySieve®.

FUNCTIONAL PRINCIPLE

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.

APPLICATIONS & METHODS

Build the process around the sample.

APPLICATION EXAMPLES

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.

Fertilizers

Soil

Cereals

Construction Materials

Mixed granular sample for particle-size separation by sieving
Agricultural soil as a sample material for particle-size analysis
Mixed cereal flakes used as a sample for particle-size separation
Granular mineral sample used for particle-size separation by sieving

TOOLS & CONFIGURATION

The right tools for the task.

ACCESSORIES

sieve shakers can be equipped with a variety of accessories to meet a wide range of application requirements.

  • Clamping units

With the 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.
