Slab Silica Sand Processing Line

Artificial quartz is a high-end, environmentally friendly decorative material with high hardness and wide applications. It uses silica sand of varying coarseness as a framework and quartz powder to fill gaps and increase density. Guote Equipment has developed a dedicated processing line that can stably produce high-purity, high-whiteness, and uniformly rounded quartz slab sand.

Slab silica sand processing line supports two mature processing methods—wet and dry—that can be flexibly selected based on specific needs. The wet process offers superior purification and higher product quality, completing the full production flow when paired with drying equipment. In contrast, the dry process features a streamlined workflow and high water efficiency. The equipment incorporates an ultra-pure protective structure and a high-efficiency magnetic separation system, effectively preventing iron contamination caused by equipment wear and ensuring stable product purity. The entire line operates in a closed, negative-pressure environment with zero dust leakage. Coupled with centralized automated control, this setup guarantees clean, environmentally friendly production, consistent quality, and lower labor costs.

PROCESS DESCRIPTION

  • 01
    Crushing
    Large raw quartz ore is transported to the crushing section via belt conveyors. Depending on the characteristics of the ore, 1 to 2 stages of crushing units are configured to reduce the ore into smaller particles.
  • 02
    Washing and Desliming
    The crushed particles are conveyed to the washing and desliming process via belt conveyors. This process is primarily carried out by a drum washer. The particles tumble and rub against each other inside the drum to remove attached mud, fine sand, and oxide scales. After being washed with water, the clean quartz sand is discharged from the tail end of the machine and transported by a belt conveyor to a temporary stockpile for natural dewatering.
  • 03
    Grinding
    The dewatered quartz sand particles are fed into a grinding hopper by a wheel loader and then evenly delivered to a white belt conveyor via a vibrating feeder (to prevent color contamination). The material then enters a vertical crusher for grinding, producing fine quartz sand particles with a particle size ranging from 4 to 120 mesh.
  • 04
    Screening and Impurity Removal
    The ground particles exit through the sand discharge outlet and enter a bucket elevator. After being lifted, they are first screened by a trommel screen. The qualified particles then fall into a high-intensity magnetic separator, which removes weakly magnetic iron impurities under a magnetic field of up to 10,000 GS.
  • 05
    Particle Size Classification and Packaging
    The high-purity quartz sand is fed into a linear vibrating screen via a bucket elevator for particle size classification. Particles of different sizes are then packed into finished product bags. The entire process of grinding, screening, impurity removal, and size classification is conducted in a closed environment. Dust is collected by a pulse-jet bag filter, ensuring dust-free production.
