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
·Spiral classifier is one of the important beneficiation equipments which is widely used in the beneficiation plants of gold iron and copper ores In this article we will mainly introduce how to choose a spiral classifier from the aspects of the introduction type and price of the spiral classifier
Introduction Spiral classifier and hydrocyclone are the main equipments for the classification operation of the concentrator Although the rapid development of the cyclone once made the spiral classifier lose its market but with the continuous changes in the requirements of the selection plant it was found that the spiral classifier also has its advantages
·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
·Hydrogritter Classifier Optimum Grit Capture and Dewatering • Heavy walled spiral shaft with protective wear shoes up to ¾ inch thick Ni Hard in larger sizes • No tank wear Spiral is suspended between two bearings operating with a bed of sand between the screw and the tank improving dewatering and eliminating tank wear common with

·In the concentrator the spiral classifier often carries out pre classification and inspection classification in the grinding circuit It can also be used in ore washing and desliming operations It is widely used in major concentrators because of its simple structure stable operation and convenient operation
6 ·Grit Classifiers are used to separate materials A shaftless spiral extracts the material eg sand that settles at the bottom of a trough The shaftless spiral allows the material to travel automatically through the system to a recovery or disposal container Our Grit Classifier is strong and Built to Last ®
·Spiral classifier Screw classifier is widely used for distributing ore in the close circuit with ball mill Advantages are simple structure reliable working condition and convenient operation The Advantages and Benefits of Sprial Classifier
·Basically the different wet classifiers are g ravity settling tank cone classifier double cone class ifier hydrocyclone classifier spiral classifier and rake classifier Gravity settling tank
·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
·The best performing classifier Multilayer Perceptron classified the motor symptom bradykinesia or dyskinesia with an accuracy of 84% and area under the receiver operating characteristics curve
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 The experimental results showed that the qualified fine materials could overflow with the shortest
