Volumetric Screw Feeders
Volumetric screw feeders allow consistent feeding of dry materials into downstream processes. These can be tuned to feed rates ranging from just a few grams or ounces per minute, to well over 100 lbs per minute by utilizing different screw diameters and pitches, as well as variable frequency drives and gear box combination’s. Screw feeders are available in mild steel and stainless steel construction.
Loss-In-Weight Screw Feeders
By mounting a feeder (screw, tube, tray, belt, etc.) to a scale platform, you can gravimetrically (Loss-in-Weight) feed material into a downstream process. This can be done as a “batch” or continuous process.
Vibratory Tray Feeders
Vibratory tray feeders can utilize electromagnetic or brute force (offset weight vibrators)to feed dry materials along a pan (or tray) into downstream equipment. These are particularly good with friable, sticky, or easily smeared materials.
Vibratory Tube Feeders
Similar to vibratory tray feeders, vibratory tube feeders can utilize electromagnetic or brute force (offset weight vibrators) and feed dry materials in an enclosed tube to downstream equipment.
