In Reply to: canary seed settings on a 1688 posted by rick on September 26, 2000 at 22:14:23:

We use settings of the following on our 2188's with specalty rotors

concave - as tight as possible (you will prob need to check the "zeroing")
top sieve - about 3/8 inch
bottom sieve - almost closed (1/4inch or so )
rotor speed - 600 - 650
fan speed - 600 - 630

you may need to run a slightly faster rotor speed on tough or green cannary and will need to make small adjustments in order to keep the sample clean & to not plug the tailings
