Wet Plastic Granulator: An Advanced Solution for Efficient Recycling
In the face of escalating global plastic waste, the Wet Plastic Granulator emerges as a specialized and highly efficient solution, turning an environmental challenge into an opportunity for innovation and profitability.
What is a Wet Plastic Granulator?
A wet plastic granulator is an advanced machine that shreds and grinds plastic into small granules while simultaneously using water in the process. Unlike dry granulators, it introduces a water flow into the cutting chamber to clean the plastic, lubricate the blades, and cool the system. This results in smoother operation, higher-quality recycled material, and reduced machine wear. These robust machines transform diverse plastics—from films to rigid containers—into valuable, reusable flakes.

Key Features
- Integrated Water Injection: A precisely engineered system sprays water directly into the cutting chamber.
- Durable D2 Steel Blades: High-carbon, high-chromium steel knives in a double-scissor or V-shape configuration ensure longevity.
- Robust Open Rotor Design: A dynamically balanced rotor spins at high speeds (400-600 RPM) for consistent granule size.
Core Advantages
- Built-in Pre-Washing: Water actively washes away dirt, dust, and labels during granulation.
- Reduced Friction & Heat: Water acts as a lubricant and coolant, preventing overheating and blade wear.
- Superior Granule Quality: Consistent cutting and cooling produce uniform, high-quality granules with minimal fines.

Frequently Asked Questions
What is the main advantage of a wet granulator over a dry one?
The primary advantage is the built-in pre-washing and cooling. The water flow cleans contaminants off the plastic while simultaneously cooling the blades, which reduces friction, prevents plastic from melting, and extends blade life. This often results in higher quality granules from dirty material.
Does a wet granulator replace a full plastic washing line?
Not entirely. While it provides excellent pre-washing, for heavily contaminated materials (like post-consumer packaging), it works best as the first step *within* a larger washing line. It enhances the overall efficiency but may not replace subsequent friction washing or float-sink tanks for achieving the highest purity.
How does water affect the maintenance of the machine?
Water significantly helps with maintenance. By cooling and lubricating the blades, it reduces the frequency of sharpening. The constant washing action also prevents dirt and melted plastic from building up inside the cutting chamber, making routine clean-ups faster and easier.
Is a wet granulator suitable for all types of plastic?
It is highly effective for most thermoplastics like PP, PE, HDPE (bottles, films, rigid items), and ABS. It is particularly advantageous for materials that are dirty or prone to melting from friction. For certain materials, a dry granulator might still be sufficient, but the wet granulator offers greater versatility.
