Centrifugal Dewatering Machine for Rigid Plastic Flakes

In the competitive world of plastic recycling, achieving low moisture content in your flakes isn’t just a goal—it’s essential for quality, efficiency, and profitability. At Energycle, we’ve engineered the perfect solution: our Centrifugal Dewatering Machine. This is a highly effective, yet low-energy-consuming piece of drying equipment, designed to be the robust workhorse of your washing line.

As the initial and most critical unit in the drying series, our machine expertly handles rigid plastic flakes (like PET and PP/PE) with high water content, dramatically reducing it to minimal levels. By integrating this machine into your PET bottle washing line or PE/PP rigid plastic washing line, you set the stage for a more streamlined, cost-effective, and higher-quality recycling process.

How It Works: The Principle of Centrifugal Force

The operational principle of our Centrifugal Dewatering Machine (also known as a horizontal centrifuge) is remarkably powerful and efficient. It shares a structural similarity with a friction washer, focusing on high-speed mechanical force to achieve its goal.

Here’s a step-by-step look at the process:

1. Material Feeding: Wet, washed plastic flakes are fed into the machine’s vertical feeder.
2. High-Speed Rotation: Inside, a long shaft mounted with numerous durable paddles spins at a high velocity, reaching nearly 1,400 rotations per minute (RPM).
3. Centrifugal Action: This rapid rotation generates immense centrifugal force, constantly throwing the plastic flakes outwards against a surrounding mesh screen tunnel.
4. Efficient Water Expulsion: The force effectively separates the water from the plastic. Water passes through the mesh screen and is collected below for disposal or recycling.
5. Conveying and Discharge: Simultaneously, the spinning paddles propel the now much drier plastic flakes along the screen towards the outlet, ready for the next stage—typically a thermal dryer.

This cost-efficient mechanical process is the first and most important step in drying. By mechanically removing the bulk of the water, our Centrifugal Dewatering Machine can reduce moisture content significantly, preparing the material for a final, much less energy-intensive thermal drying phase.

Key Features & Benefits: Your Competitive Advantage

Choosing Energycle’s machine is an investment in your plant’s efficiency and your product’s quality.

• Exceptional Drying Performance: Drastically reduces moisture levels, which is crucial for producing high-quality pellets in the subsequent extrusion stage.
• Massive Energy Savings: By taking the heavy load off your thermal dryers, this machine significantly cuts down on your plant’s overall energy consumption and operational costs.
• Dual-Action Cleaning: The high-speed friction not only dries but also provides a final scrubbing action, helping to remove fine contaminants and labels, further purifying your plastic flakes.
• Robust and Reliable Construction: Built with high-grade materials, including stainless steel for all parts in contact with water and plastic, ensuring longevity and preventing rust contamination.
• Operator-Friendly Maintenance: Designed for the real world, with easily accessible and replaceable mesh screens to minimize downtime and simplify routine maintenance.

Frequently Asked Questions (FAQ)

Q1: What types of plastic is this dewatering machine best for?
This machine is specifically designed and optimized for rigid plastic flakes, such as crushed PET from bottles, and rigid PP/PE flakes from drums, pipes, or crates. It is not suitable for soft plastics like PE films.

Q2: What is the typical moisture level after using this machine?
For rigid plastic flakes, you can expect our centrifugal dewatering machine to reduce the moisture content to an impressively low 2-3%. This provides an ideal foundation for the final drying stage.

Q3: How does this machine contribute to cost savings?
The primary saving comes from energy. Mechanical dewatering is far more energy-efficient than thermal drying (evaporation). By removing most of the water first with our machine, your thermal dryer has much less work to do, leading to substantial savings on electricity or gas bills.

Q4: Is the mesh screen difficult to clean or replace?
Not at all. We’ve designed the machine for easy access. The screen housing can be opened quickly, allowing operators to clean, inspect, or replace the screen with minimal downtime, keeping your production line running efficiently.

Q5: Can this machine be integrated into my existing washing line?
Absolutely. Our Centrifugal Dewatering Machine is designed for seamless integration into existing PET or PE/PP washing lines. We can provide technical support to ensure it fits perfectly into your current setup, positioned right after the final rinsing tank.
