China Water-Cooled Strands Pelletizer System Manufacturer — Granuwel
The Water-Cooled Strands Pelletizer is a pelletizing equipment specifically designed for thermoplastic plastics and polymers. It produces uniform, high-quality pellets through the method of cutting after strand cooling.This system is suitable for various plastic materials, particularly for application scenarios requiring stable cooling and efficient continuous production.
The Water-Cooled Strands Pelletizer adopts a unique method combining strand forming with water cooling. It extrudes molten plastic into strands, which are cooled in a water tank and then cut into pellets by rotating blades. The entire process is highly automated, resulting in uniform particle shape and excellent flowability, making it suitable for high-volume production.
The equipment mainly consists of host extruder, water tank cooling system, pelletizing die head, dewatering system, vibrating sieve, and control system, ensuring an efficient and stable production process.
Water-Cooled Strands Pelletizing System Features
The Water-Cooled Strands Pelletizer is an ideal choice in the plastic pelletizing field due to its wide applicability, high output, stable pellet quality, operational efficiency, and ease of maintenance. The specific advantages are as follows:
Wide applicability
It is suitable for most general plastics such as PP, PE; thermoplastic plastics such as TPE, TPO, etc.; including PP, PE; engineering plastics such as ABS, PA, PS, PEI, PEEK, etc., and recycled material. It is especially suitable for materials requiring higher cooling rates.
High output and continuous production
Utilizes efficient water cooling and automatic pelletizing design, enabling long-term continuous production. Single-machine output can reach 1-5 tons/hour, meeting medium to large-scale production demands.
High pellet uniformity
Strand forming is stable, cutting size is precise, pellets have consistent shape and excellent flowability, facilitating subsequent processing and packaging. Pelletizer blade speed is adjustable to meet the cutting needs of different plastics.
Operational efficiency
The water-cooling system recycles cooling water, resulting in low energy consumption. Enclosed design reduces dust and volatile emissions, meeting environmental requirements.
Ease of maintenance
Modular design allows key components (such as cutting blades) to be replaced quickly, reducing downtime and improving production efficiency.
