PFM-18L-S Powder Feeder
Low rate feeder up to
Proven ability to feed difficult powders PFM-18L Screw Feeder overcomes both flooding and clogging problems associated with difficult-to-handle powders. Unique feeder trough effectively de-aerates and contains the powder at the initial fill cycle to prevent flooding. An independently driven agitator maintains optimum material conditioning while screw speed can vary to control feed rate. Material does not build up within the trough or tube, preventing binding or erratic feed. Unique THAYER® weight sensing technology provides isolation from all force vectors except material weight for superior sensitivity and accuracy.
Optional rotating trough & hopper speeds material change-out, makes cleaning
easier. Ideal for self-empty remaining material away from process. For both
screw and vibratory feeder models
Thayer Scale's "scale disturbance control" Superior scale design and patented control algorithms assure reliable, accurate metering under harsh industrial conditions. The model 18L scale design provides high sensitivity to even the smallest weight changes. The measurement of weight loss is accomplished with a unique flexure scale system coupled to an accurate, very sensitive, high output electronic force measurement sensor. Feeder "dead" weight (weigh hopper, motor, speed reducer, etc.) is mass-counterbalanced so that material weight only is measured. This feature helps assure excellent control even in "noisy" environments. |
