Automatic Screw Feeders for Efficient Assembly

To use a screw feeder, load your bulk material into the inlet hopper, set the desired feed rate on the variable speed drive controller, and start the unit. The rotating screw conveys material at the programmed rate into downstream equipment. For automated processes, the feeder can be integrated with PLC, SCADA, or DCS systems for continuous, hands-free operation and real-time feed rate adjustment.

An automatic screw feeder operates by rotating a helical screw at a controlled speed — governed by a variable frequency drive — to push metered volumes of bulk material through a tube or trough. The feed rate is set automatically via a control system (PLC/SCADA/DCS) and adjusted in real time to match upstream and downstream process demands, ensuring consistent, accurate material dosing without manual intervention.

Jersey Crusher's volumetric screw feeders handle a wide range of bulk solid materials including fine powders, granules, flakes, pellets, and irregular bulk solids. They are used for APIs, excipients, food ingredients, spices, grains, chemicals, plastics, animal feed components, biomass, and more. Material-specific configurations are engineered based on customer-provided product samples to ensure reliable flow and accurate dosing.

Yes. Jersey Crusher offers feeders constructed from 316 sanitary stainless steel with GMP-aligned, easy-clean designs supporting cGMP cleaning validation requirements. Tool-free disassembly options, air purge shaft seals, and food-grade interior finish options make our feeders compliant with FDA-adjacent food-contact surface specifications and suitable for regulated pharmaceutical and food manufacturing environments.

Absolutely. Jersey Crusher's volumetric feeders are designed for seamless integration with SCADA, PLC, and DCS control systems via standard industrial signal protocols. Standard 230/460/3/60 TEFC motors paired with variable frequency drives allow precise feed rate matching with both upstream and downstream process equipment, making them plug-compatible with most automated production control architectures.

Jersey Crusher's volumetric feeder systems are available across a broad capacity range — from small-scale laboratory and pilot-scale units for formulation development and testing, through to high-capacity industrial feeders for large-scale continuous production. All configurations are engineered-to-order based on your specific throughput targets, material characteristics, and process integration requirements.
