Shandong 3,000t/d Quartz Glass Sand Mineral Processing Plant

Pre-screening and Initial Washing: The raw ore is conveyed to the pre-screening machine via a feeder belt equipped with a scale. The undersize product is directly fed into a spiral ore washer for preliminary washing to reduce the ore's mud content.

Scrubbing: The pre-washed material is then scrubbed in a scrubbing machine to further clean the ore surface.

Desludging and Slurry Balancing: The slurry produced after scrubbing is pumped into a desludging hopper located above the grading tower via a slurry pump. Here, sand, mud, and impurities are separated, further reducing the mud content and simultaneously balancing the slurry.

Particle Size Classification (I): Coarse sand is separated. The desludging product enters a secondary drum screen to separate the coarse particles larger than 26 mesh. This +26 mesh coarse sand is transported to the coarse sand yard for storage as a product.

Particle Size Classification (II): Fine sand is separated from qualified products. The fine product below 26 mesh on the drum screen enters a thickening hopper and hydraulic classifier. The hydraulic classifier is responsible for separating fine particles below 140 mesh (0.1mm).

Magnetic Separation and Iron Removal: The qualified particle size products separated by the drum screen and hydraulic classifier enter a high-magnetic plate magnetic separator (magnetic field strength of 10,000-11,000 GS). This equipment primarily removes all mechanical iron and some weakly magnetic iron.

Dehydration and Finished Product Stacking: After iron removal, the product enters a thickening hopper for dehydration. After completion, it is transported to a storage shed for stacking as the final qualified product.
