Page 27: Principle Of Operation
6.2 Principle of Operation The AS 450 control performs a vibratory sieving, where the sample material is thrown upwards by the vibrations of the sieve bottom and subsequently falls back down onto the sieve mesh fabric due to gravitation forces. Thereby, the sample material is subjected to a three- dimensional movement, i.e. -

Page 33: Amplitudes In Dependence On The Load
7.5.1 Amplitudes in Dependence on the Load The AS 450 control is a resonance sieving machine whose attainable amplitude is depending on the load. In this respect, the mass (sieve stack and sieve clamping unit) fixed to the sieve plate (ST) plays a primary role. -
Page 34: Time
With the AS 450 control the amplitude is defined as the total lifting height (SH) of the test sieve. For example, with a set amplitude of 1.2 mm, the test sieve is displaced in the range of -0.6 mm... -
Page 35: Interval
Controlling the Device An optimum amplitude has been found, when a state of statistical resonance is being reached during the sieving process. Then, the particles have the biggest probability of passing, as the throw time of a particle corresponds to the oscillation period of the test sieve. In this case, the particle (PA1) will be moved with a different orientation to a different mesh every time the test sieve (SH) lifts. -

Page 40: Performing The Wet Sieving
Wet Sieving 8.1 Performing the Wet Sieving Usually, sieving processes are carried out dry. However, when agglomerates, electrostatic charges or a high degree of fines impede the sieving process, either sieving aids can be used, or a wet sieving can be performed. For wet sieving, a liquid, preferably water, is supplied to the sample material during the sieving process. - Page 41 Wet Sieving Suspend the sample material in a beaker containing the liquid intended for the wet sieving. To reduce the surface tension and to facilitate the screenings of the material later on, a few drops of surfactant may be added. ...
