In a lab float test, you adjust to agitator’s RPM based on the volume of the tank you’re working with. Here are suggestions.
Rougher Cell:
Total cell volume =3.3 liters
Slurry volume = 2.5 liters (until this mark slurry filled) –> I use 1000 g test charges
Cleaner Cell:
Total cell volume =1.75 liters
Slurry volume = 1 liter I use whatever the rougher conc charge is.
