Spiral Classifier

Hongji Group Product Superiority

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.

Our spiral classifiers are widely used in the distribution of ore in closed circuits with ball mills, grading ore and fine slit in gravity mills, grading granularity and flow of metal ore-dressing, and de-sliming and dehydrating in washing. Advantages are simple structure, reliable working condition and convenient operation.

According to the principle that different grains are with different specific gravity and sedimentation rate in the liquid, the fine ore flows in the water and the coarse ore sinks in the bottom. The classifier that has machine grading by discharging from the top can filtrate the materials and send coarse materials to the feeding mouth and discharge the fine material from the pipe. The seat of the machine adopts channel steel and body adopts armor plate and the spiral axle adopts wrought iron, so it's durable. The lifting equipments have two types, by electricity and hand.

The Classification of Spiral Classifier

Spiral classifiers are mainly classified into high weir single and double spiral classifier, low weir single and double spiral classifier, and immersed single and double screw classifier. Nowadays, low weir type one is not very common, high weir type and immersed type are preferable.

The Advantages of Hongji Spiral Classifier

1. Energy saving.

2. Adjustable particle size.

3. Applicable for wide range of industries.

4. Simple to control the purity of ore sand.

5. Compact structure and reliable operation.

6. Easy to maintain and low repair rate for adopting tile lining.

7. Concise operation for adopting the technology of inverter control.

The Working Principle Of Spiral Classifier

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. Hongji 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.
