THE PRODUCT IN FOCUS

Model overview

The analytical sieve shakers of the series AS 200 are used in research & development and quality control of raw materials, interim, and finished products as well as in production monitoring. The controllable electromagnetic drive offers an optimal adaption for every product. Sharp fractions are obtained even after short sieving times.

The AS 200 digit cA sieve shaker is recommended whenever controlled amplitude, digital display of vibration height and time, and interval operation are required.

PRODUCT ADVANTAGES

  • NEW: controlled amplitude
  • suitable for dry and wet sieving
  • excellent separation efficiency even with short sieving times
  • efficient electromagnetic drive
  • 3-D throwing motion which ensures optimum use of the open sieve area and lets the sample move equally over the whole sieving surface
  • maintenance-free
  • sieve stack up to 510 mm height
  • free adjustment of all process parameters (time, amplitude)
  • interval operation (fix 10 s)
  • digital display of vibration height and time
  • easy operation, ergonomic design

WET SIEVING WITH VIBRATORY SIEVE SHAKERS

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 can be used for wet sieving. There are special accessories like clamping lids with spray nozzle and collecting pans with outlet available. By placing venting rings between the sieves, air cushions can expand without letting liquid or sample material escape.

FUNCTIONAL PRINCIPLE

Each vibratory sieve shaker of the series AS 200 is equipped with an electromagnetic drive that is patented by (EP 0642844). This drive produces a 3D throwing motion that moves the product to be sieved equally over the whole sieving surface.

The advantage: high stress capacity, extremely smooth operation and short sieving times with high separation efficiency.

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.

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.
