Inclined Screw Conveyor Feeder for Granule Material Handling

Product introduction of Inclined Screw Conveyor Feeder

The inclined screw conveyor is an efficient vertical and inclined material conveying solution designed for transferring dry powders, granules, and bulk materials between different production stages. It is widely used in food processing, chemical manufacturing, pharmaceutical production, and other industries requiring hygienic and reliable material handling.

The conveyor uses a stainless steel screw conveying system to provide smooth and continuous feeding from ground-level loading areas to elevated equipment such as packaging machines, mixers, fillers, and processing systems. The large-capacity hopper allows convenient material loading, while the integrated vibration function helps improve feeding performance for materials with poor flow characteristics.

Designed with a simple and practical structure, the inclined screw conveyor features easy disassembly, quick cleaning, and low maintenance requirements. The stainless steel frame without painted surfaces helps maintain hygienic operation, making it suitable for applications with strict cleanliness requirements.

This screw conveyor provides an efficient alternative to manual handling and vacuum feeding systems by reducing labor requirements, improving production efficiency, and ensuring stable material supply.

Working principle

The inclined screw conveyor works by using a rotating screw shaft inside the conveying tube to move materials continuously. Materials are loaded into the ground-level hopper and enter the screw conveying section through the inlet.

As the screw rotates, materials are pushed forward along the inclined tube and lifted to the required discharge height. The controlled screw rotation ensures stable and uniform material feeding into connected equipment such as packaging machines, mixers, fillers, or production systems.

For materials with poor flow characteristics, the vibrating hopper assists material movement and prevents bridging or blockage. The enclosed conveying structure helps reduce dust contamination while maintaining a clean working environment.
