Fujian 3,000t/d Quartz silica sand processing plant

Ore Pre-selection and Impurity Removal: Large particles of debris are removed through screening.

Scrubbing: After impurity removal, the material enters a scrubber for scrubbing. The resulting slurry is then pumped through a slurry tank to a desludging hopper.

Desludging: Desludging and impurities are removed in the desludging hopper, and the slurry is piped to a water treatment system for sedimentation.

Coarse Grain Screening and Grading: The underflow slurry enters a blocked settler and drum screen for screening. The +26 mesh material is returned to the ceramic ball mill through a return pipe for re-grinding. The treated minerals return to the post-scrubbing slurry tank, forming a closed-loop coarse sand production cycle.

Grading and Fine Sand Collection: The overflow from the blocked settler (-26 mesh slurry) is piped to a thickening hopper and hydraulic classifier; the overflow from the hydraulic classifier (-150 mesh slurry) is collected in a fine sand collection area for drainage.

Magnetic Separation and Purification: The hydraulic classifier underflow (qualified products with a mesh size of 26-150) is subjected to a medium-magnetic plate magnetic separator to remove mechanical iron. It then passes through a high-magnetic plate magnetic separator (12,000 GS) to remove all mechanical iron and some weakly magnetic iron. Finally, it passes through a vertical ring high-gradient magnetic separator (1.5 T magnetic field, two units connected in series) for electromagnetic iron removal.

Finished Product Dewatering and Shipping: After magnetic separation, the product is transported to the finished product area via a slurry pump. It is dewatered through a thickening hopper and dewatering screen, then conveyed by a finished product conveyor belt to the finished product area for drainage and ready for shipping.

Water Treatment and Tailings Sludge Treatment: Water treatment utilizes multi-stage thickening tanks for sedimentation. The underflow sludge is then pumped to a plate and frame filter press via a slurry pump to recover water, forming a sludge cake for subsequent processing.
