Color Masterbatch Polishing Machine Plastic Granule Film Coating Line
Product Description
Product Overview
Nanjing Haisi Extrusion Equipment Co., Ltd. supplies the high-efficiency Color Masterbatch Polishing Machine (Plastic Particle Film Coating Machine). Designed specifically for plastic masterbatch producers, this continuous auxiliary equipment applies a uniform wax coating or surface polishing agent onto raw granules. It dramatically enhances the surface gloss, color brightness, and aesthetic quality of finished color masterbatches while efficiently cooling the particles and collecting residual dust.

Advanced System Structure & Working Principle
The complete polishing unit integrates three core synchronized subsystems:
Precision Feeding & Flow Control Mechanism: Utilizes an extraction plate and adjustable speed control cage to regulate both the granule intake and the precise dosing of polishing wax/agents, ensuring optimal coating ratio.
Dual-Stage Polishing & Waxing Chamber: Features specialized wax-coated rollers and secondary polishing rollers. Granules are evenly coated in the upper roller and refined in the lower roller, resulting in a smooth, high-gloss finish without agglomeration.
Integrated Air Net & Dust Extraction System: Equipped with a heavy-duty exhaust fan (1500 m³/h) and cyclone collector to rapidly cool the granules (stabilizing the surface wax layer) while vacuuming fine ash and micro-powders.
Technical & Performance Advantages
Superior Surface Aesthetics: Significantly improves the gloss and color vibrancy of masterbatch pellets, meeting premium quality requirements for high-end injection molding and film blowing applications.
Clean & Dust-Free Pellets: Integrated pneumatic cooling and ash extraction remove loose fines, preventing dust accumulation during packaging and downstream processing.
Controllable Coating Thickness: Operators can easily fine-tune the wax feed speed and pressure rod weights to achieve the exact surface effect required for different formulation recipes.
Durable & Low Maintenance: Built with wear-resistant bushings, heavy-duty bearings (6215/6216), and easy-access screen frames for straightforward maintenance and quick screen replacement.
Typical Applications
This specialized auxiliary equipment is ideal for processing:
High-end color masterbatches (PE, PP, ABS, PET, EVA)
Black and white masterbatches requiring high surface shine
Functional additive pellets and special polymer compounds
Plastic recycling granules needing surface aesthetics improvement
