Its compact structure and excellent sealing performance ensure enclosed, dust-free operation while supporting multi-point feeding and discharging.
Available in diameters from 100 mm to 1250 mm with conveying distances up to 70 meters, the system can be customized for different installation conditions. With a simple structure, low maintenance requirements, and optional mixing functionality, it provides a durable, flexible, and cost-effective feeding solution for modern industrial production lines.
JR Auger Screw Feeder Hopper Series
The Jiarui Auger Screw Feeder Hopper series is widely used as continuous conveying equipment in the metallurgy, building materials, chemicals, grain, and mechanical processing industries. It is primarily designed for the horizontal transport and vertical lifting of loose materials, including various powders, granules, and small blocks. Compared to other feeding equipment, the Auger Screw Feeder Hopper offers significant advantages, including a small overall cross-sectional dimension, excellent sealing performance, smooth and reliable operation, and flexible multi-point loading and unloading. Its simple structure ensures ease of operation and maintenance, providing an efficient and robust solution for material feeding and conveying systems.
Working principle
A small Auger Screw Feeder Hopper is a continuous conveying system that uses a rotating screw blade to move materials axially through a closed trough or tubular casing. With a compact structure, excellent sealing performance, and minimal footprint, the Auger Screw Feeder Hopper is widely used for handling powder, granular, and small bulk materials in horizontal or slightly inclined conveying applications.
The working principle of the Auger Screw Feeder Hopper is based on the rotation of the screw shaft. As the screw rotates, materials are pushed forward along the trough due to gravity and friction with the casing, similar to how a fixed nut moves linearly along a rotating screw. Inside the Auger Screw Feeder Hopper, material transport relies on this continuous pushing force, resulting in a stable and efficient sliding movement that ensures consistent and controlled conveying performance.

How to Choose the Right Auger Screw Feeder Hopper
Selecting the appropriate Auger Screw Feeder Hopper requires a comprehensive evaluation of operating conditions, material characteristics, and conveying requirements. A well-matched model ensures stable performance, long service life, and reduced maintenance costs.
1. Material Characteristics
The Auger Screw Feeder Hopper is suitable for powders, granules, and small bulk materials with good flowability. For optimal performance, consider bulk density (typically 0.5–1.3 t/m³), moisture content, temperature, and viscosity to determine the appropriate screw type and configuration.
2. Conveying Direction & Distance
- Horizontal or slightly inclined (≤20°): Standard Auger Screw Feeder Hopper is recommended
- Vertical conveying: Use a vertical-type configuration with lifting height ≤8 m
- Typical conveying distance: ≤40 m (maximum up to 70 m depending on design)
3. Temperature Conditions
- Ambient operating temperature: -20°C to 50°C
- Horizontal conveying material temperature: ≤200°C
- Vertical conveying material temperature: ≤80°C
4. Capacity Requirements
Determine the required throughput (m³/h) to select the correct screw diameter and speed. Larger diameters and optimized pitch designs increase conveying capacity.
5. Installation & Layout
The Auger Screw Feeder Hopper supports multi-point feeding and discharging, making it suitable for flexible production line layouts. Drive units can be configured as single-end or dual-end drive depending on system requirements.
6. Model Selection (GX / LS / LC Types)
- GX Type Auger Screw Feeder Hopper: Standardized, stable performance, suitable for general horizontal conveying
- LS Type Auger Screw Feeder Hopper: Widely used, multiple diameter options (100–1250 mm), flexible configuration
- LC Type Auger Screw Feeder Hopper: Designed for vertical conveying and compact installations
