spiral classifiers -considering theirapplications and costs. Although in use for decades in the mining industry, spiral classifiers have lost a lotoftheirimportance due to the development ofcyclones.
The ore sample was subjected to classification using the spiral classifier at varying washing speed (20-40 rev/min), washing residence time (30-90 mins) and the feed tonnage also (6-8 t) to determine the optimum operational conditions for maximum Mn grade.
The role of the classifier has an impact on the efficiency of the mill. Therefore, the selection of grading equipment is a key point in the process of beneficiation. Spiral classifiers can be divided into single spiral classifiers and double spiral classifiers according to the number of screw shafts.
