Screw Feeders

Carolina Conveying offers both Volumetric and Gravimetric Screw Feeders.

Rite-Rate Volumetric Screw Feeders

Volumetric screw feeders are used to accurately discharge product at a controlled rate. Carolina Conveying offers two styles: a Sanitary Style and General Purpose.

The Sanitary Style Feeder has a U shaped feed trough and agitating blades, this unit is shown to the left. The agitating blades keep the product alive and flowing down into the feed screw. This unit works well on products that are more likely to bridge, rathole or have large clumps that need breaking up. Quick release options on the feed tube, feed screw and front panel make this unit easy to clean and ideal for sanitary applications or applications require frequent product changes. This unit is available in mild steel or stainless steel. Sizes range from 1 inch through 4 inch feed screw with numerous types of screw designs to best control product flow.

The General Purpose Feeder has a V shaped feed trough and vibrator motor. The hopper is mounted on isolation mounts. This unit works well on all free flowing products, or those that require minimal agitation to keep product flowing into the screw. This unit is available in mild steel or stainless steel, and can also be fitted with a quick release feed screw and feed tube. Standard sizes range from 1 inch through 4 inch feed screw. Large size feeders are also available.

Rite-Weight Gravimetric Screw Feeders

Both the Sanitary Style Feeder and General Purpose Feeder may be used for gravimetric applications. This includes batch loss-in-weight, batch gain-in-weight, continuous loss-in-weight and continuous gain-in-weight. For loss-in-weight applications, the feeder is mounted on load cells that constantly monitor the weight of material in feeder. A controller monitors the weight loss from the feeder to accurately control batch sizes or discharge rates. For gain-in-weight applications, the feeders are filling a hopper or other device downstream. The controller in this case monitors the weight gain and controls the screw feeder accordingly. Typical accuracy is +/- 0.5%.Rite-Weight Gravimetric Screw Feeders.

Batching Systems

Carolina Conveying has supplied numerous systems, integrating product storage and feeder accuracy together. Product storage can be with our Bulk Bag Discharge Station, Solibin IBC System, Hoppers or Bag Dump Stations. For hoppers with poor flowing products, we offer the Bin Activator and Soliflo to insure product discharge. Allowing Carolina Conveying to integrate your system requirements not only insures accurate batches, but also product flow from storage.

Rite-Weight Gravimetric Screw Feeders

The Screw Feeder is also used for gravimetric applications. This includes batch loss-in-weight, batch gain-in-weight, continuous loss-in-weight and continuous gain-in-weight. For loss-in-weight applications, the feeder is mounted on load cells and a controller monitors the weight loss from the feeder to accurately manage batch sizes or discharge rates. Typical accuracy is +/- 0.5%.
