A screw feeder, or screw conveyor, utilizes a rotating helical screw (auger) within a tube or trough to reliably move bulk materials. Its primary function is precise, controlled metering and transfer of dry, free-flowing, or semi-solid substances like powders, granules, pellets, flakes, or chips. Screw feeders ensure consistent, dust-controlled material flow from storage (silos, hoppers) to processing equipment (mixers, reactors, packaging lines). Their design offers accuracy, reliability, and containment for diverse materials.

Non-standard customized U-tube screw feeders are specialized material handling systems designed for unique industrial challenges. Their defining U-shaped housing securely encloses a rotating screw, efficiently conveying bulk solids – powders, granules, flakes, or pellets – along a defined path. Key functions include precise, controlled feeding of difficult materials (sticky, abrasive, fragile), gentle handling to prevent degradation, and creating a sealed environment to prevent contamination or dust emission. Customization allows tailoring dimensions (length, tube diameter, screw pitch), materials of construction (stainless steel, coatings), hopper design, drive power, and discharge configuration. Applications are diverse, spanning industries requiring specific solutions: precise ingredient dosing in Food & Beverage or Pharmaceutical production, handling abrasive minerals in Chemicals, conveying fragile catalysts in Petrochemicals, managing sticky polymers in Plastics, or automating processes in specialized Agriculture or Recycling plants where standard feeders fall short. They streamline feeding where conventional options fail.
