a centrifugal dryer dewatering machine. Such machines are typically used in industrial settings to remove moisture from materials using high-speed spinning. This process helps in reducing the moisture content of various products, making them easier to process further or package. The machine is robust, featuring a large, blue rectangular frame housing the spinning mechanism, with a motor mounted on top and various inlets and outlets for the material and water.

Centrifugal Dryer Dewatering Machine: Efficient Water Removal

A crucial piece of equipment designed to remove moisture from plastic materials, ensuring high-quality recycled plastics. Excess moisture can lead to defects, reduced strength, and hinder downstream processes like extrusion and injection molding.

How It Works

This machine utilizes high-speed centrifugal force to effectively remove surface moisture from washed plastic materials.

  • 1. Material Loading

    Plastic fragments or pellets are fed into the machine’s rotating drum.

  • 2. High-Speed Rotation

    The drum spins at high speeds (1000+ RPM), generating powerful centrifugal force.

  • 3. Water Expulsion

    Centrifugal force pushes moisture outwards through perforations in the drum screen.

  • 4. Dry Material Discharge

    The drier plastic materials are discharged, ready for the next stage of processing.

Key Benefits

  • Enhanced Product Quality

    Minimizes moisture-related defects, resulting in high-quality recycled plastics with improved physical and mechanical properties.

  • Increased Processing Efficiency

    Drier materials lead to higher throughput and greater productivity in extrusion, injection molding, and compounding.

  • Energy and Cost Savings

    Reduces the energy required for heating in subsequent drying processes, lowering costs and your environmental footprint.

  • Waste Reduction

    Ensures recycled plastics meet industry standards, minimizing product rejection, waste, and the need for reprocessing.

Primary Applications

  • PET Bottle Recycling Lines
  • Plastic Film Washing Lines
  • Rigid Plastic Recycling (HDPE, PP)
  • Pre-drying for Pelletizing Systems

Frequently Asked Questions

A centrifugal dryer uses mechanical force to quickly remove the majority of surface water, making it very energy-efficient. A thermal dryer uses heat to evaporate the remaining moisture to achieve very low levels (e.g., under 3%). They are often used together in a washing line for optimal results.

Depending on the material type and size, a centrifugal dryer typically reduces moisture content to around 5-10%. It serves as the primary, high-capacity dewatering step before final thermal drying.

Absolutely. The screen is a key wear part and is designed for easy replacement. We offer screens with different perforation sizes to suit various plastic materials and ensure long-term, efficient operation.
