·However slow the spiral speed down as much as possible for the classifier used in the second stage grinding or fine grinding cycle In summary lower rotational speeds are generally used in spiral classifiers especially for large spiral classifiers For example to obtain coarse overflow the speed of a spiral with a diameter of two meters
A spiral classifier is a mineral processing equipment which receives an ore slurry input and performs a gravity separation process between Classifier Vibrations and Accuracy

·Spiral classifier is widely used in mineral processing plants with a ball mill as a closed circuit circuit to separate the flow of ore sand or used in gravity concentrators to grade ore sand and fine mud and metal beneficiation processes to grade the size of ore pulp and washing operations in the desliming hopper dehydration and other
The Spiral Classifier is available with spiral diameters up to 120″ These classifiers are built in three models with 100% 125% and 150% spiral submergence with straight side tanks or modified flared or full flared tanks All sizes and models are available with single double
