Introduction

Driven by the wave of circular economy, fiberglass recycling and reuse technology is gradually becoming the focus of the industry. This technology completes the crushing pretreatment through a double shaft shredder, achieves nanometer level fine grinding through a PNMP pulverizer, and is further purified and recovered by an efficient dust removal system. Finally, the waste fiberglass is converted into high-performance filling material, successfully achieving partial replacement of traditional calcium carbonate.

Core equipment

Double shaft shredder
The double shaft shredder uses an alloy steel blade shaft to shear and crush waste fiberglass, producing uniform fragments. The low-speed high torque design avoids resin adhesion and efficiently separates metal impurities, providing high-quality raw materials for subsequent grinding.

PNMP pulverizer
The PNMP grinding machine achieves fine processing of fiberglass through grinding disc technology, equipped with a multi-stage grinding disc structure, which can accurately control the particle size distribution of the powder and adapt to the performance requirements of fillers in fields such as plastics, rubber, and coatings.

Dust removal system
The composite dust removal system consists of a cyclone separator and a pulse bag filter, which is the core guarantee of process environmental protection. The cyclone separator separates large particle powders through centrifugal force to achieve primary recovery; The pulse bag filter uses membrane filter material to efficiently filter particles, ensuring that exhaust emissions meet standards.

Recycling advantages

The use of recycled Fiberglass powder as a substitute for calcium carbonate has significant advantages: its retained high strength, high modulus, and high temperature resistance can significantly improve the mechanical properties and weather resistance of composite materials, and its reinforcement and toughening effect is better than that of calcium carbonate; By utilizing waste resources to reduce raw material costs and reducing the use of high-performance powders, comprehensive cost optimization can be achieved;
