Stainless Steel Screw Conveyor for Powder and Granular Material Handling – High-Performance Feeding Machine for Industrial Applications

The stainless steel screw feeder, also known as a spiral auger conveyor or Jiaolong feeding machine, is engineered for efficient and reliable transportation of fine powders and granules across diverse industries. Designed with food-grade materials and robust construction, this vertical or horizontal screw conveyor ensures seamless operation in environments demanding hygiene, durability, and precision. Ideal for chemical processing, grain handling, mining operations, and pharmaceutical manufacturing, it meets international standards for material compatibility and safety.

This industrial-grade feeding system features a fully stainless steel body—except for motors, bearings, and frames—making it resistant to corrosion, oil, acids, alkalis, and saline conditions. Its sealed design prevents dust leakage, ensuring clean working environments while minimizing product loss. The unit operates smoothly in multiple orientations: horizontal, inclined, or vertical, offering flexibility for integration into existing production lines. With customizable specifications including hopper size, conveying height, motor position, and inlet port shape (circular or square), it adapts easily to unique facility requirements.

Key advantages include high strength, excellent anti-stick properties, and easy maintenance due to its smooth internal surfaces and optional gear plate design. Whether used standalone or directly connected to supporting equipment like mixers, reactors, or packaging systems, the screw feeder delivers consistent flow rates without clogging. It’s particularly effective for sticky or abrasive materials where traditional conveyors may fail. Customization options allow users to tailor performance parameters such as screw pitch, rotation speed, and tube diameter (e.g., 159mm round tube) to match specific process needs.

Common applications span across food processing plants requiring sanitary handling of flour, sugar, or spices; chemical facilities managing catalysts or pigments; feed mills distributing animal feed pellets; and mining operations transporting powdered ores. Because of its versatility, this auger conveyor serves both batch and continuous processes, enhancing productivity and reducing downtime. It's especially suited for industries prioritizing compliance with FDA, EU GMP, or ISO standards for food-safe and non-toxic material contact surfaces.

Customer feedback highlights the reliability of the device under heavy-duty conditions, ease of cleaning, and minimal wear over extended use. Users often praise the manufacturer’s commitment to quality control—each unit undergoes full testing before shipment—to guarantee optimal performance upon arrival. Many appreciate the ability to order custom-built units based on technical drawings or physical samples, which demonstrates strong support for niche or specialized applications.
