Stainless Steel Screw Conveyor System for Salt Transport

Product introduction of Stainless Steel Screw Conveyor

The Stainless Steel Screw Conveyor System is a versatile and widely used industrial conveying solution designed for efficient transport of bulk materials. It utilizes a rotating screw blade inside a sealed trough or pipe to push materials from the inlet to the discharge outlet.

This equipment supports horizontal, inclined, and vertical conveying modes, making it highly flexible for different factory layouts. Constructed from stainless steel, it ensures durability, corrosion resistance, and hygienic performance, making it suitable for food-grade and industrial applications.

It is commonly used for powders, granules, small blocks, and loose materials across multiple industries, ensuring continuous and controlled material flow.

Working principle

Step 1: Power Transmission
The motor drives the reducer, which converts high-speed rotation into stable torque, ensuring controlled operation of the screw shaft.

Step 2: Material Feeding
Bulk materials such as powder, granules, or small solids enter through the inlet hopper and are evenly distributed into the screw channel.

Step 3: Screw Conveying Action
The rotating screw flights push material forward along the enclosed tube or trough, creating continuous axial movement without backflow.

Step 4: Flow Control Adjustment
A frequency converter or fixed-speed reducer regulates motor speed, allowing precise control of conveying capacity based on production requirements.

Step 5: Stable Discharge Output
Material is smoothly discharged at the outlet with consistent flow, ensuring stable feeding for downstream equipment such as mixers, packaging machines, or storage systems.

Step 6: Continuous Operation Cycle
The system operates in a closed-loop continuous mode, enabling 24/7 industrial conveying with low noise, low maintenance, and high efficiency.
