NOTE
Wet sieving
–
For wet sieving to be successful, please observe the following instructions
:
• The inside diameter of the water supply hose to the spraying nozzle must
be 13 mm.
• During the wet sieving a water pressure of between 2 bar and 5 bar is
recommended at the sieve cover entry (approx. 2 litres/min
– 4 litres/min).
These values depend on the sieve mesh size used, sieve material and
collecting pan loading.
• Use ventilation bases between the sieves.
• The water outlet from the drain hose must be below the water sieve outlet
(W1).
• The spacing between the water outlet from the drain hose and the water
sieve outlet should not be too large. (W2)
• The inside diameter of the water drain hose must be sufficiently large.
(Inside diameter of hose is 20 mm)
• Used sieves must be cleaned immediately after the sieving process.
Depending on the material being sieved, a rust film can form in the sieve
mesh.
