Introduction to Spiral Separator

Spiral separator or spiral classifier is one type of machine used in ore beneficiation and it is a machine that relies on the principle that the solid particles with different proportions have different falling speed in the liquid to complete mechanical classification. This machine is able to classify and filter the materials discharged from the grinding mill, and screw in the coarse materials by using the spiral blade to the feeding mouth of the grinding mill and discharge the filtered fine materials from the overflow pipe. Spiral classifier can be called classifier for short. The classifiers can be divided into four types, namely, high weir single-spiral classifier, high weir double-spiral classifier, immersed type single-spiral classifier and immersed type double-spiral classifier. Because spiral classifier can also classify gold ore and copper ore, so, it is also called gold ore spiral classifier and copper ore spiral classifer.

Spiral classifier is widely used for separating sand in the ore beneficiation plant to equip with ball mill to form a closed cycle, for classifying ore sand and fine silt in the gravity separation plant, for the granularity classification of the pulp in the metal ore beneficiation flow and for removing the slime and water in the ore washing process. This classifier has the advantages of simple structure, reliable working condition and convenient operation.

The classifiers produced by Hongxing Machinery is widely used for separating the sand in the ore beneficiation plant to equip with ball mill to form a closed cycle, for classifying ore sand and fine silt in the gravity separation plant, for the granularity classification of the pulp in the metal ore beneficiation flow and for removing the slime and water in the ore washing process. This classifier has the advantages of simple structure, reliable working condition and convenient operation.

This classifier is mainly composed of transmission system, spiral part, chute, lifting part, upper support and ore discharging valve. 

Working Principle of Gold ore spiral Classifer

The spiral classifier for gold ore 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. This machine is 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. The pedestal of this machine 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.
