Quartz slab sand production line

Process Description

• 01

  Crushing

  Large quartz ore pieces are transported to the crushing section via belt conveyor. Depending on the ore's characteristics, 1-2 stages of crushing units are set up to break the ore into smaller particles.

• 02

  Washing and Desliming

  The crushed particles are conveyed to the washing and desliming process via belt conveyor. This process is mainly completed by a drum washing machine. The particles roll and rub inside the drum, removing surface-adhered mud, fine sand, and oxide scale. After being washed by water, they become clean quartz sand, discharged from the tail end of the machine, and transported by belt conveyor to a temporary storage yard for natural dewatering.

• 03

  Grinding

  The dewatered quartz sand particles are fed into the grinding hopper by a loader, and then evenly fed to a white belt conveyor (to avoid color contamination) by a vibrating feeder. They then enter a vertical crushing machine for grinding, obtaining fine quartz sand particles with a particle size of 4 to 120 mesh.

• 04

  Screening and Impurity Removal

  The ground particles enter a bucket elevator through the sand discharge port, and after being lifted, they are first screened by a drum screen. Qualified particles fall into a high-intensity magnetic separator, where weakly magnetic ferrous impurities are removed under a magnetic field of up to 10,000 GS.

• 05

  Particle Size Sorting and Packaging

  High-purity quartz sand is fed into a linear vibrating screen by a bucket elevator for particle size classification. Particles of different sizes are packaged into finished product bags. The entire grinding, screening, impurity removal, and particle size sorting process is carried out in a closed environment, and dust is collected by a pulse-jet bag filter, achieving dust-free production.
