The spiral classifier uses turbulence in the washing media to separate coarse and fines/micro-fines. The larger particles settle down in a tub bottom. The inclined screw rakes up and delivers them at the upper end. The slurry with finer particles flow over a weir to a drain. This simple equipment is used extensively in sand washing and mineral recovery applications Model & Sizes: Spiral Dia 600 to 1800 mm; Raking Capacity: 15 to 200 TPH
