The ANALYSETTE 18 is a Heavy Duty Analytical Sieve Shaker which was especially built for the processing (dry sieving or wet-sieving with a conversion kit) of large amounts of sieving materials. It specifically eliminates the disadvantages of lighter sieve shakers, where the weight of the sample and the sieves may at least partially influence the sieving results. Where ever manual sieving has to be replaced due to economical reasons or for improved reproducibility, the ANALYSETTE 18 is perfect. Through the use of automatic sieve evaluation, sieving results are not only faster available, but also more dependable. Mistakes during weighing and during the calculation of the individual sieve functions become obsolete, since the entire evaluation is performed via computer.

Areas of application

The ANALYSETTE 18 is used for particle size analysis and portioning of coarse-grained materials. The maximum input quantity of 15 kg for the material to be sieved and the sieve stack also allows use in pilot line production or for serial analysis of large quantities.

Method of operation

The ANALYSETTE 18 is a Heavy Duty Analytical Sieve Shaker that was specially designed for processing of large sieving quantities. It intentionally avoids the disadvantages of lighter sieve shakers in which the sample and sieve weights can sometimes significantly affect the sieving results. Two unbalanced motors situated in phase opposition under exactly defined angles create optimal vibrations of the test sieves mounted to the sieve plate. After elapsing of the sieve time, both motors are precisely braked. With this construction the sieving material is not only accelerated vertically, but also horizontally. This three-dimensional sieving action ensures a permanent change of direction of the material. This results in a short sieving time and increased separation efficiency without manual re-sieving and optimal reproducibility.

Software AUTOSIEVE

The multilingual software AUTOSIEVE for automatic evaluation, simple monitoring and documentation of your sieving results is supplied on a practical USB stick and is therefore very quickly installed. All you have to do is to connect a laboratory analysis balance and then weigh the sieves before and after sieving using differential weighing. AUTOSIEVE will do the rest. The software, which is suitable for Windows 7, XP and Vista, enables simple saving and retrieving of empty sieve weights, both of single sieves and complete sieve sets.

Equipment

The standard equipment delivered with the Heavy Duty Analytical Sieve Shaker ANALYSETTE 18 includes tensioning and sieve cover, but does not include test sieves or sieve pan. For sieving fine-grained materials or agglomerates, the use of for example vulkollan cubes are recommended.
