Automatic Screw Feeding System for Salt Powder Transport

Product introduction of Automatic Screw Feeding System

The Automatic Screw Feeding System, also known as an auger feeder, screw conveyor feeder, or volumetric screw dosing machine, is engineered for accurate material conveying and controlled feeding applications. It is widely used for transporting flour, powder, grains, pellets, spices, additives, chemicals, and bulk materials in automated production environments.

Designed with food-grade stainless steel construction and precision screw feeding technology, this industrial powder feeding machine ensures smooth conveying performance, stable output, and minimal material waste. The system integrates easily into packaging machines, mixers, filling lines, batching systems, and processing equipment.

Its modular structure, customizable hopper capacity, and adjustable feeding speed make it suitable for both light-duty and heavy-duty industrial operations.

Working principle

Step 1: Powder, flour, granules, or pellets are loaded into the storage hopper.

Step 2: The industrial motor activates the auger screw rotation system.

Step 3: The rotating screw transfers materials through the conveyor tube.

Step 4: Variable speed control regulates volumetric feeding accuracy.

Step 5: Materials discharge evenly into mixers, packaging machines, reactors, silos, or processing equipment.

Step 6: The system synchronizes with automated production lines for continuous industrial operation.
