How to Design Efficient and Reliable Feeders for Bulk Solids

Gravimetric feeders should be used whenever there is a requirement for close control of material discharge. Examples include when the feed rate uniformity must be better than ±2%, or sample collection times must be less than about 30 sec. A gravimetric feeder should also be used when the bulk density of the material varies. Criteria for Feeder ...
