Guttridge Screw conveyor with scale

• Transferring bulk ingredients such as grains, powders, and granules within food production lines.
• Feeding processing machinery with measured quantities of raw materials.
• Moving products between different stages of a food processing operation, such as mixing or packaging.
• Handling waste products or by-products in a controlled manner.
• Dosing specific amounts of material into hoppers or storage containers.

Typical throughput

Throughput for this class of equipment typically ranges from a few hundred kilograms to several tonnes per hour, depending on screw diameter, pitch, and motor power.

Power supply

Units of this type commonly operate on a 3-phase industrial power supply, typically 400V, 50Hz in the UK.

Material of construction

For food processing applications, screw conveyors are typically constructed from stainless steel (e.g., 304 or 316 grade) to meet hygiene standards.

Elevation range

Mobile screw conveyors commonly offer adjustable elevation, typically ranging from floor level up to 2-3 metres, suitable for feeding various processing equipment.

Screw diameter

Common screw diameters for this type of unit range from 100mm to 250mm, influencing material flow and capacity.

Integrated weighing

Units with integrated scales commonly handle batch weights up to 50kg, suitable for precise ingredient dosing.

Mobility

Many smaller and medium-sized screw conveyors are designed to be mobile, featuring castors for easy relocation within a facility.

• What types of materials can this screw conveyor handle?

  This type of screw conveyor is typically suitable for free-flowing dry bulk materials such as powders, granules, pellets, and flakes. It is less suited for sticky, abrasive, or very large lump materials.

• Is this unit suitable for outdoor use?

• What maintenance is typically required for a screw conveyor?

• Can the discharge height be adjusted?

• How accurate is the integrated weighing system?

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.
