    Spiral Classifier, Dewatering Screw This spiral classifier/dewatering screw is a multipurpose machine As a classifier, it separates out the smaller waste particles from the ore processor tailings The larger particles can then be returned to the grinding circuit for finer grinding to liberate more values Many locations don’t have a ready source of water, so when used as a dewateringGrit Classifiers or also known as a grit screw, grit separator or grit classifier are used at wastewater plants at the headworks (front end of the plant) to help separate the grit from organics and water Grit removal needs to be done at the headworks of plants to help reduce wear to upstream pumps and mechanical equipment Grit can also cause pipe blockage and reduce the effective volume ofGrit Classifier Basics: What is a Grit Classifier? JMSGRITSEP® DS Grit Classifiers consist of an inclined screw conveyor with a large volume hopper including an inlet spout and a water outlet spout, a shaftless screw housed in a trough, a lowfriction antiwear trough liner, a trough cover, an outlet spout for solid particles, and a drive unit mounted at the outlet end Function Water to be cleaned flows through the inlet spout of the GRITSEPGrit Classifier Hydroscrew Screw Conveyors

  • Screw classifier features and working principle | LZZG

    The screw classifier is divided into submerged and high weir type according to the structure The overflow weir position of the high weir classifier is higher than the center of the bearing at the lower end of the screw shaft but lower than the upper edge of the spiral of the overflow end It has a certain settlement area, suitable for coarse particle classification, and can obtain overflowThe screw classifiers or screw washing machine has simple structure, reliable work, convenient operation, etc The working principle of spiral classifiers is as follows as the different sizes and proportions of the solid particles lead to the different settling velocities in the liquid, the fine mineral particles floating in the water overflow and the coarse ones sink to the bottom Get PriceHow A Screw Classifier WorksThe J+A screw classifier systems are freestanding units used for the separation of mineral grit from other types of solids The screw classifier hopper maintains the required water level through a series of weirs A peripheral weir removes floating solids and a second weir, positioned within the trough wall, removes other solids that are lighter than gritJ+A Screw Classifier
