Sterlco SF1000 Gravimetric Additive Feeder - Manual (Page 30)

Notes:
1. Recommended for use in cases of "hard" dispersing (flowing) materials.
2. Standard hopper size is 3 liters. However, in cases when the material consumption is
very high (either due to very short cycles or to high MB batches), larger hoppers (5L
or 10L) should be considered. The recommended rules are:
a) Not more then 1 hopper's fill each 3 minutes (max. 20 fillings/hour)
b) [Max Fill (gr)
– Min Fill (gr)] / MB batch (gr) > 5-6
