In mineral processing, the Akins AKA spiral or screw Classifier has been successfully used for so many years that most mill operators are familiar with its principle and operation. This classifier embodies the simplest design, smallest number of wearing parts, and an absence of surge in the overflow. It separates c…
Spiral classifier uses the principle of the proportion different of solid particles, so the precipitation speeds is also different in the liquid. Fine mineral particles float in the water and overflow; the coarse ore particles settle on the bottom of the channel. Material is discharged from the upper by spiral, so as to finish the grading work.
Applications of Spiral Classifier. Mining Plants: Used in conjunction with ball mills to form a closed-circuit for ore sand separation and classification.; Gravity Separation: Applied for classifying ore sand and fine mud to enhance mining efficiency.; Metal Ore Dressing: Used in the ore dressing process for size classification of ore pulp to meet subsequent …
Spiral classifier 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 ...
Hydrocyclones are suitable for processing fine-grained materials; if the amount of ore feed is uneven, a spiral classifier should be used. If you have other questions about the selection of hydrocyclones and spiral classifiers, you can consult the online customer service and leave a message, we will contact you as soon as possible!
The fundamental reason for the low efficiency of spiral classifiers is that the fine- heavy ore particles and the coarse-light ore particles are settled in disorder during the classification process, resulting in an equal drop phenomenon, causing that desilting sand contains huge amount of fine sands and the overflow particles are too coarse.
In production, many concentrators more or less encounter the problem of obvious decline in the classification efficiency of spiral classifier, and the root cause of this problem lies in the disordered settlement of fine and heavy ore particles and coarse and light ore particles in the classification process, resulting in equal drop phenomenon, resulting in a large …
