Sand washing plant

The FSM grit classifier is used to separate solids from water. The unit can be charged via air jet lift, pump or free flow. The FSM grit classifier consists of a separating container and a screw conveyor. Application areas range from municipal sewage plant to separation of sediment and heavy materials in production and process waste water in the chemical, food, paper and waste disposal industries. The grit separator provides high performance coupled with low operating costs. Functional principle: Inflow of the grit/water mixture can be either under pressure or via gravity line. The tangential feed induces a rotary movement in the water which causes (Type SK) the heavier substances such as sand to sink to the apex of the tank, where they are removed and dewatered via the screw conveyor. The grit is thus rendered substantially free of organic matter. The grit classifier Type TSK is feeded from the top with the grit water mixture. The FSM grit classifier effects a continual separation of the grit from the waste water flow while reducing the organic portion of the solids and dewatering the grit.
