In plastic recycling plants, one of the biggest challenges is handling lightweight, thin, and low bulk density materials such as PE film, PP woven bags, raffia, agricultural film, and soft plastic scraps.
A plastic agglomerator, also known as a densifier or granulation pre-processor, plays a critical role by converting loose plastic waste into compact, semi-molten granules that are easy to feed into extrusion pelletizing systems.
Without an agglomerator, recycling lines often face feeding instability, low output efficiency, and inconsistent pellet quality.
A plastic agglomerator is a high-speed friction heating machine that processes soft plastic waste into dense agglomerated particles through controlled mechanical cutting, heating, and rapid cooling.
It is commonly installed before:
Plastic pelletizing lines
Recycling extrusion systems
Film reprocessing lines
Waste plastic compounding lines
The agglomeration process significantly improves material flowability and feeding stability.
The working process can be divided into four stages:
High-performance rotary blades rotate at speeds up to 700–900 rpm, generating strong friction heat that softens plastic surfaces.
The softened plastic sticks together under controlled temperature, forming semi-molten clusters instead of full melting.
The built-in automatic water flushing system rapidly cools the material, preventing over-melting and stabilizing particle shape.
The finished material exits the discharge port as uniform dense granules, ready for extrusion feeding.
Ideal for recycling:
LDPE film
HDPE film scraps
Mulch film waste
Packaging film
Used for:
Cement bags
Big bag scraps
Raffia woven plastic waste
Efficient for recycling:
Thermoforming sheet edges
Packaging trimming waste
Soft plastic offcuts
Agglomerators serve as a feeding stabilization unit before:
Single screw pelletizers
Twin screw compounding extruders
Water ring pelletizing systems

Suitable for small workshops and large industrial recycling plants.
| Model | Pot Volume (L) | Output (kg/h) | Motor Power (kW) | Rotary Speed (rpm) |
|---|---|---|---|---|
| QS-300 | 300 | 150 | 55 | 900 |
| QS-500 | 500 | 300 | 90 | 850 |
| QS-600 | 600 | 400 | 110 | 850 |
| QS-800 | 800 | 550 | 132 | 700 |
Dense agglomerated material feeds smoothly into extruders without bridging or air gaps.
Stable feeding allows pelletizers to operate at higher throughput rates.
Uniform material reduces screw load fluctuations and motor stress.
Consistent feeding leads to uniform pellet size and melting quality.
Thin films require higher friction heat control and blade speed optimization.
Choose appropriate model size based on desired kg/hour throughput.
