The basic structure, classification principle and low efficiency of the traditional spiral classifier were analyzed. The trial industrial comparative experiment was carried out by using φ300×4500 spiral classifier with the two-sided overflow and the port side overflow at the same parameter.

 · This work concerns the application of a vibrating fork densitometer to the measurement of overflow density in spiral classifiers. A spiral classifier is a mineral processing equipment which receives an ore slurry input and performs a gravity separation process between the solids particles of ore and the water. The classifier has two outputs: …

 · In ore dressing production, the spiral classifier is mainly used for one stage grinding and grading, and together with the ball mill to form a closed-circuit grinding. In the daily work, if the spiral classifier fails, it will not only affect the grinding production, but also affect the normal operation of the entire beneficiation process.

 · Abstract: In order to investigate the impact of density on the classification behavior of particles in the static classifier of Vertical Spindle Mill, the sensitivity of overflow yield to the increase of air amount for narrowly sized pyrite, carborundum, quartz and coal samples were compared in a lab-scale classifier, respectively.

 · The spiral classifier is also a mechanical classifier. It is made by combining a gravity settler of rectangular section with a sloped transport spiral for the sediment. It consists of a semi cylindrical trough (a trough which is semi-circular in cross- section) inclined to the horizontal.

Sturtevant air classifiers balance the physical principles of centrifugal force, drag force and gravity to generate a high-precision method of classifying particles according to size or density. All three Sturtevant air classifiers offer durable construction, as well as time- and energy-saving advantages. Whirlwind

 · The concept is initially validated through computational fluid dynamics (CFD) simulations. Preferential movement of coarser particles, which experience greater centrifugal force, to the outer periphery was observed. These predictions are validated by conducting experiments on a 3D printed spiral classifier.
