Classifier refers towards the rotary separator, and that is belongs to Ore Milling Equipment applied to separate the dust and impurities from sand through the buoyancy impact of water. The agitation in the spiral can attain the purpose of filter moisture and impurities, lifting and transportation, and stirring throughout the lifting procedure, to produce uniform sand with out the difference of fine sand and coarse sand.

Characteristics: Classifier has traits of long screw entire body, superior sealing system, basic construction, sturdy processing capability, easy to retain, minimal water and clay in finished sand, and so on. Hence, it is extensively employed in ore mining sector, mineral processing plant by type closed loop with ball mill to varied sand mine, gravity concentrators to classify ore and fine clay, metal ore dressing method for particle size grading of pulp, at the same time as desliming and dehydrating operation in ore washing procedure.

Working principle: Classifier separates dust and impurities from sand by the principle that materials with distinct particle dimension and density includes a various velocity from the fluid. Materials with fine particle size and smaller density of has a modest and slow velocity, although materials with large particle size and higher density includes a rapidly sedimentation velocity. Furthermore, the evenly stirring from the spiral slice can reach the objective of filter moisture and impurities, lifting and transportation.
