Understanding Spiral Classifier
What is a spiral classifier? Dressing equipment spiral classifier is one of the machines for mineral processing. It is a device that separates materials by density in a spiral water flow, referred to as a classifier. Spiral classifier is widely used in mineral processing plants to form a closed-circuit cycle with a ball mill to separate mineral sand, or to classify mineral sand and fine mud in gravity mineral processing plants, and to classify the particle size of slurry in metal mineral processing processes, and to remove mud and water in mineral washing operations.
The sorting density is generally not less than 1.6g/cm3, and the E value is between 0.15 şi 0.25. În prezent, the specifications of spiral separators produced at home and abroad mainly include models with diameters of 650mm, 750mm, 900mm, 1000mm and 1100mm.
Structura clasificatorului spirală
The spiral classifier is mainly composed of slurry distributor, feed pipe, spiral trough, center column, product interceptor, product discharge pipe and frame. The spiral trough is divided into three sections: stable trough, variable diameter trough and discharge trough. The spiral blades are connected with bolts and fixed to the bracket with bolts. Each spiral classifier is equipped with single-head, double-head and multi-head spiral troughs.

What is the difference between a spiral classifier and a spiral separator?
Spiral classifiers are mainly used for classification by particle size and are commonly found in grinding circuits in mineral processing. Their function is to separate the ground material into “overflow” (fine particles) şi “nisip” (coarse particles) according to particle size, ensuring that the particle size of the material in the subsequent process meets the requirements.

Spiral separators are mainly used to sort materials by density or magnetic differences. They are often used to sort metals and non-metals, minerals of different densities, or recyclables in solid waste (such as scrap metal sorting). The core is to achieve separation through density differences.
