  Scrubbing and desludging: The raw sand passes through the buffer hopper, the belt scale, and the pre-selection screen to screen out the coarse materials. The finer materials enter the scrubber for mud and sand separation. After separation, the materials enter the slurry pool, and then are pumped into the desludging bucket on the grading tower through the slurry pump. The desludging bucket performs secondary desludging to reduce the mud content of the materials.

  Grading and dehydration: The desludging materials enter the hydraulic classifier. The hydraulic classifier mainly separates the fine materials of 140 mesh (adjustable) and finer products of 140 mesh by gravity principle. The +140 mesh materials are adjusted through the concentration bucket and then enter the dehydration screen. The dehydration screen is to reduce the moisture content of the raw ore, separate the water and sand, and produce the semi-finished products with the qualified particle size requirements of +140 mesh. After natural drying, the materials are drained and the moisture content is controlled within 10%.

  Drying and screening: The materials in the buffer silo enter the dryer through the conveyor belt to dry the sand until the moisture reaches the standard requirement. After drying, the materials pass through the bucket elevator and the buffer hopper and enter the swing screen (linear screen) for screening with different mesh sizes of 16-20, 20-40, 40-70, 30-50, and 70-140. After screening, the qualified materials are packaged as finished products.
