Screw Auger

• Transferring bulk dry or semi-dry ingredients in food processing.
• Moving granular materials in chemical and pharmaceutical production.
• Feeding packaging machinery with consistent product flow.
• Handling powders and small particulates in agricultural settings.
• Conveying waste products or by-products in various industrial processes.

Typical throughput

Varies significantly based on material density, screw diameter, pitch, and speed, but for this class of equipment, it typically ranges from 1 to 10 cubic metres per hour.

Power supply

Commonly requires a 3-phase electrical supply, typically 400V, 50Hz, with motor sizes generally between 0.75kW and 4kW depending on application.

Material of construction

Units of this type are typically constructed from 304 or 316 grade stainless steel, particularly for food-grade or corrosive applications.

Footprint

For a mobile inclined unit, the footprint is typically compact, designed for flexibility within a production area.

Incline angle

Screw augers can operate at various incline angles, commonly up to 45 degrees, though efficiency decreases at steeper angles.

Suitable feed materials

Typically handles free-flowing powders, granules, pellets, and some sticky or cohesive materials, though specific screw designs are optimised for different product characteristics.

• What maintenance is typically required for a screw auger?

  Routine maintenance commonly involves checking motor and gearbox oil levels, inspecting bearings for wear, and ensuring seals are intact. Regular cleaning, especially for food-grade applications, is also essential.

• Can this type of auger handle abrasive materials?

• Is it possible to control the feed rate?

• What are the common safety features on screw augers?

• How easy is it to clean for product changeovers?

Buyers typically value conveyor systems for their reliability and longevity when well-maintained. Key considerations when purchasing used units include belt condition, motor functionality, frame integrity, and available spare parts. Industry sentiment emphasises the importance of verifying operational history and cleanliness standards, particularly for food handling applications. Common strengths include robust construction, relatively straightforward maintenance requirements, and cost savings versus new equipment. Reputable manufacturers' models tend to hold their value well and integrate readily into existing production lines.
