Spiral Classifier

There are four main types of classifiers: high weir single spiral and double spiral, submerged single spiral and double spiral. This classifier is widely used in ore dressing plants to form a closed-l...

    Description

    The Spiral Classifier is also called the screw sand washer,  or the stone washing machine as its input material size can be up to 30 mm.

    The spiral sand washer is designed to provide a bigger capacity and higher cleaning level than a traditional sand screw washer. It is widely used for cleaning materials in quarry, minerals, building materials, transportation, chemical industry, water conservancy, hydropower, cement mixture station, and so on. 


    Spiral Classifier Types:

    MINGXIN supplies two types of spiral sand washing machines:  a single-screw sand washer and a double-screw washing machine.


    Advantage

    • Three functions in one machine: cleaning, dewatering, and grading.
    • High efficient. Cleaning and upward conveying at the same time.
    • Low water consumption.
    • Impellers use wear-resistant plates or polyurethane materials to reduce the running cost.
    • Designed for large capacity volume and also lower investment.


    Structures & Working Principle

    Spiral Classifier Structure

    The main parts of a spiral sand washer include electric motor, big and small belt pulleys, triangle belt and gear reducer.


    Spiral Classifier Working Principle

    When a spiral is working, the spiral sand washer needs to adopt an inclination of 15 ° tilt. Under the water tub, 3 weir plates form the sediment pool. The spiral head is immersed in this pool, and the spiral is driven by an electric motor through reducer rotating continuously. The freshwater is fed from the porous plate at bottom of sediment pool, and the washed sand is discharged on the top side and delivered by belt conveyor.
