A spiral screw auger can be used as a classifier as well as a dewatering device. During classification, the lighter material floats through to the tailings, while the heavier material rides the spiral to be deposited in another container. MBMM’s spiral classifiers are engineered to provide years of reliable service. Our USA ­made machines:

Screw Classifier Ore Spiral Classifier Spiral Classification Equipment Screw Classification Equipment. GTEK Spiral Classifier Description. Spiral classifier is one of the beneficiation devices. Spiral classifier achieves the purpose of classification based on the differing of solid particles in specific gravities. ... Spiral classifiers mainly ...

Spiral classifiers or screw classifiers are important ore dressing equipment. Spiral classifier is mainly used in metal beneficiation production line to classify minerals according to their different sedimentation velocity. Screw classifiers can be divided into high weir type, low weir type and sank type according to the height of the weir.

The spiral classifier also named the screw classifier or the spiral classifier machine works as a type of sand classifier or screw sand washer by using the working principle of materials with different particle sizes and weights tending to sink in the liquid at different speeds.

Jones Attwood Screw Classifiers. The screw classifiers provide a means to convey grit to a grit collection point The incline of the classifers aids dewatering. The screw classifier hopper improves grit settlement of a range of particle size and aids separations of floating solids.

For this highly abrasive application, the DeltaCLASSIFIER (Grit Classifier) is supplied with a stainless steel housing and high strength, abrasion resistant, alloy steel shafted screw. Weldon hardening or bolton wear shoes are also available.

Grit Classifier and Twin Classifier. The SA Grit Classifier and DA Twin Grit Classifier are grit conveying, washing, and dewatering units. The settling tanks of the SA and DA Grit Classifier are carefully designed to effectively separate grit from wastewater or grit slurry.

Sep 28, 2012· shanghai spiral classifiers, also named screw classifiers, are designed to provide the most effective pool area and overflow velocity requirements bybining the proper submergence of the spiral ...

Classifier Washers Classifiers and Washers are used to separate sand or grit from a liquid slurry or sludge. Our experienced Sales and Engineering staff are waiting and prepared to help you with all your material handling equipment needs.

2. The dewatering screen of the high mesh classifier and the cyclone are organized in one unit. 3. Twostage sludge high mesh classification (stage 1 for classifier and stage 2 cyclone high mesh classification) for 200mesh or below is to remove

The HydroGrit™ Classifier is designed for the separation, dewatering and removal of settleable inorganic material typically at the inlet/headworks of a municipal or industrial wastewater treatment plant. ... The screw diameter and consequently the grit classifier model varies according to the volume of grit to be dewatered.
