Effective sieving of large quantities The ANALYSETTE 18 is the robust, Heavy Duty Analytical Sieve Shaker from FRITSCH. It can effortlessly sieve up to 15 kg of material between 20 μm and 125 mm. The three-dimensional sieving motion ensures particularly fast sieving results without manual re-sieving, and also optimal reproducibility. 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. It is particularly suitable for particle size analysis and portioning of coarse-grained materials through dry sieving or wet sieving with conversion kit. WORKING PRINCIPLE 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.
