VOP Ultra Series Machine Vision Sorter

Equipped with ultra-high resolution RGB imaging technology, it removes discolored particles and heterogeneous particles in quartz sand based on differences in optical properties. It adopts single-pass feeding and two-stage sorting to greatly improve SiO₂ purity.

Quartz sand purification presents a unique sorting challenge: even trace impurities can cause severe quality degradation. Within the particle size range of 26–120 mesh, discolored grains, iron oxides and gangue minerals are often visually indistinguishable, yet they can significantly impair chemical performance, undermining the optical transparency, color consistency and structural integrity required for high-end industrial applications. For artificial stone manufacturers, photovoltaic glass producers and quartz processors in the glass and ceramic sector, the ability to detect and remove these fine impurities with ultra-high precision — without introducing secondary contamination or excessive energy consumption — is critical to delivering end products that meet stringent high-end market specifications and command premium pricing.

The VOP Ultra Series is an ultra-high-precision sorting system based on machine vision, custom-built for the purification of 26–120 mesh quartz sand to achieve purity levels unattainable by conventional sorting equipment. Powered by advanced Ultra-High Resolution RGB (UHR-RGB) visible light imaging technology and robust data processing capability, the system accurately identifies and eliminates fine impurities that compromise material quality — including discolored particles, iron oxides and gangue minerals — to produce end products compliant with high-end industrial specifications.

Featuring contamination-free operation and low energy consumption, it delivers an economical and eco-friendly sorting solution. It helps artificial stone manufacturers, photovoltaic glass producers and quartz processors substantially raise product purity and cut quality-harming impurities, consistently supplying quartz sand products that meet strict standards of the glass and ceramic industry.
