China Professional Underwater Strand Pelletizer Manufacturer — Granuwel
The underwater strand pelletizer consists of a dual-column screen changer, strand die head, guide trough, pelletizer, dehydrator, and vibrating screen, among other components. The screen changer typically features a large filtration area to effectively filter out impurities from the material. The pelletizer is made entirely of stainless steel, with cutting knives made of corrosion-resistant and wear-resistant materials, capable of effectively resisting the corrosion of water rust. The particle size is D3*3mm. The dehydrator can effectively remove moisture from the particles, yielding dry granules.
