FL Spiral Classifier

FL Spiral Classifier

Spiral classifier is one of the ore dressing equipment, which is mainly used for the pre classification, grading and inspection in ore dressing, grinding circuit of sand plant as well as desliming, dehydration and other operations in sand washing process. Therefore, spiral classifier can also be called mineral processing spiral classifier or spiral sand classifier.Service online

Detailed introduction

Introduction

According to the number of spiral, spiral classifier can be divided into single spiral classifier and double spiral classifier; according to the submerged overflow surface depth of spiral blade, it can be divided into high weir type and submerged types.

Spiral classifier is widely used in mineral processing plant to form closed cycle way with ball mill for split mineral sand, or used in gravity concentrator to grade ore and fine mud, or the size grading of slurry in ore dressing process as well as desliming, dehydration and other operations in ore washing operations. It has the characteristics of simple structure, reliable work, convenient operation, etc.

Working Principle

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 coarse ore particles are pushed by the spiral to the upper part and discharged. spiral classifier is able to filter the powdery particle crushed by the grinding mill and whirl the coarse particles with the spiral to the feeding mouth of the grinding mill and discharge the filtered fine particles.
