Spiral Classifier

Spiral Classifier Introduction

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.

Spiral Classifier Features

1. Screw classifier can conveniently control the content of sand powder to meet users' requirements.
2. Spiral classifier has advanced technology and simple process, particularly suitable for large and medium-sized sand making production line.

Spiral Classifier Working Principle

1. Spiral classifier is a type of classifying machine that classifies materials based the principle that the solid particles with different sizes and proportions have different falling speed in the liquid, and fine ore particles float in the water and coarse ore particles sink to the bottom of the chute and the coarse ore particles are pushed by the spiral to the upper part and discharged.

2. Fote screw classifiers are able to filter the powdery particle crushed by the grinding mill and whirl the coarse particles with the spiral to the feeding mouth of the grinding mill and discharge the filtered fine particles.

3. The pedestal of spiral classifiers is made of U-steel, and the rack is welded with steel plate. The water feeding head and spindle nose of the spiral shaft are made of cast iron with wear-resisting and durable property and the lifting device is divided into power-operated type and manual-operated type.
