Laminated Glass Recycling Equipment

The challenge in recycling laminated glass lies in the strong bond between the glass and the organic interlayer film (such as PVB, EVA, or SGP). Due to the presence of this film, laminated glass cannot be fed directly into a smelting furnace like ordinary waste glass. SUNYGROUP’s laminated glass recycling equipment offers an ideal solution to this problem by addressing these specific material characteristics.

The laminated glass recycling equipment employs physical separation and sorting technologies. Waste laminated glass first undergoes a pre-compression stage to disrupt the surface structure of the glass. Certain process steps may incorporate brief water immersion or temperature-controlled treatment to weaken the adhesion between the PVB interlayer and the glass.

The material then enters the laminated glass separator. The laminated glass recycling equipment utilizes differential-speed squeezing and shearing from multiple pairs of rollers, combined with high-speed kneading by hammers, to crush the glass into fine particles. This process breaks the glass away from the interlayer while maintaining the relative integrity of the film (PVB/EVA), thereby achieving effective separation of the glass and the film.

This laminated glass recycling process not only resolves the environmental pollution associated with traditional landfill disposal but also transforms waste glass and high-value PVB film into valuable resources, delivering both economic and environmental benefits.
