Screw Classifier How Works westernriverranch

Ja Screw Classifier. Ovivo screw classifiers the main purpose of the classifier is to carry out such separation so as to effect a definite change in the size composition of the granular material at the same time the classifier accomplishes the equally important function of dewatering the grit and elevating it for discharge. Chat Online.


The SAM dewatering screw is designed to separate the grit from the grit / water mixture coming from the grit chamber. The mixture enters the system through an air separator (A) or cyclone separator (A), and falls into the inlet hopper (B, where a constant volume of water is maintained via an overflow weir. This area acts effectively
