Spiral Classifier for Lead Beneficiation Zimbabwe

Spiral classifier is widely used for distributingin the close circuit with ball mill, grading slurry in the gravity mill, grading granularity in the flow of metal ore-dressing and deszenith anddehydrating in the washing.

Spiral Classifier Main Application

The spiral classifier produced by CathayPhillips is designed for slurry tank and flooding rate in proportion. According to the difference of spiral’s depth in over-flow surface, the design of tank can be also divided into straight type (ST), modified frame (MF), and flaring frame (FF). To achieve a better control of slurry, it is necessary to make the height and area of slurry tank proper. Undoubtedly, our spiral classifier can help you control the granularity size well.CathayPhillips Spiral Classifiers have exported to , Italy, Turkey , Australia , Singpore, Indonesia, Vietnam , Iran, India, Chile, Venezuela, Libya, Angola, Kenya, South Africa, Pakistan , Yeman, Eygpt, Nigeria, Tajikistan , Saudi Arabia , Zimbabwe, Dubai, Vietnam, Philippines, Brazil.

Spiral Classifier Working Principle

Generally, there are two types of spiral classifier: single spiral classifier and double spiral classifier.According to the depth of spiral blade in the flooding end, spiral classifier can also divided into high weir typeand immersed weir type. Their features are as follows:

1.High weir type: the top of spiral blade is higher than the flooding level, and the center of blade is lower than the flooding level. It is fit for classification of the ore with flooding size between 0.083-0.15mm.

2.Immersed wire type: the spiral blade is fully immersed in the flooding size. It is used to make a clear classification of the ore with flooding size between 0.15 and 0.07mm

The Spiral Classifier is Applicable for

Separation of fine granularity and liquids from coarse particles

Separation of light particles from heavy ones

Grading the final products according to the particle size

Separation of liquids from solid particles
