Longwood Rotapak150 Screw compactor

• Dewatering and compacting screenings from wastewater treatment plants.
• Reducing the volume of various wet waste streams in food processing.
• Handling and compacting sludge or fibrous materials in industrial settings.
• Processing municipal solid waste for volume reduction prior to disposal.

Typical capacity

For this class of equipment, capacities commonly range from 0.5 to 5 cubic metres per hour, depending on the material and screw configuration.

Power supply

Units of this type typically require a 3-phase electrical supply, commonly 400V, 50Hz, with motor sizes generally between 1.5 kW and 7.5 kW.

Screw diameter

Common screw diameters for compactors in this range are typically between 150mm and 300mm, influencing throughput and material handling capability.

Material of construction

Compactors are commonly constructed from stainless steel (e.g., 304 or 316) for contact parts, ensuring corrosion resistance and hygiene, particularly in food processing applications.

Footprint

The footprint for a screw compactor of this capacity typically requires a floor area of approximately 2 to 4 square metres, plus access for maintenance.

Maintenance requirements

Routine maintenance typically involves checking screw wear, gearbox oil levels, and motor bearings. Regular cleaning of the screening area is also essential.

• What types of materials can a screw compactor handle?

  Screw compactors are designed to handle wet, fibrous, and often abrasive materials such as screenings from wastewater, food waste, and various industrial sludges. The specific material suitability depends on the screw design and construction.

• How does a screw compactor reduce waste volume?

• Is this equipment suitable for continuous operation?

• What are the typical installation requirements?

• Can this unit be integrated into an existing processing line?

Food processing waste management systems are valued for their ability to handle organic waste streams efficiently and support regulatory compliance. Buyers typically prioritize robust construction, reliability, and ease of maintenance when purchasing used units. The equipment's reputation centres on its importance for operational sanitation and waste reduction. When buying second-hand, inspectors should verify mechanical condition, check for corrosion or wear, and confirm documentation of regular servicing. Reputable systems typically demonstrate durability and consistent performance across varied food processing environments.
