The Analysette 18 is a vibratory sieving machine that is suitable for particle-size analysis and grading of coarse-grained materials.
It avoids the disadvantages of lighter sieving machines, in which the sample and sieve weights can sometimes bias the sieve results.
The maximum feed quantity of 25kg for sieving material and sieve stack means it can also be used in pilot plant production or in test series for larger quantities.
It is used wherever manual sieving is replaced by mechanical sieving in order to lower costs or achieve greater reproducibility.
A maximum sample quantity of up to 6kg can be processed in the measuring range of 63um to 63mm.
Sieve process times are between 10 and 30 minutes.
The evaluation programme autosieve means that sieving results are more reliable and available more quickly.
This avoids weighing and calculation errors for the individual sieve fractions, as the computer carries out the complete analysis.
Two unbalanced motors installed in phase opposition under exactly defined angles create optimum vibration of the analysis sieves mounted on the sieve plate.
Both motors are precision braked at the end of the sieving time.
This design means that the sieved materials are accelerated vertically as well as horizontally, causing the material to change direction continuously, thus producing shorter sieving times and sharper separation results.
