Distribution of the sieved product
Even in procedures with only a single sieve, the AS200
will provide largely uniform distribution of the product
across the sieve screen. Depending on the vibration
height which is selected, the product will be moved
slowly in a circular direction.
Proper leveling of the AS200 is an important factor here.
Leveling can be corrected by screwing the feet CC in or
out as required. Fig. 19

It is not necessary to lock the feet in position once
adjustment has been made.
When carrying out sieving processes with only one to
three sieves, we recommend using the short rods.
Overly long rods, extending above the stack, will interfere
with distribution of the product due to their intrinsic reso-
nance.
