Spiral classifier

Product Category : Ore processing machine

Introduction of spiral classifiers

High weir type ore spiral classifier: the top side of spiral blade is higher than the flooding level and the center of the blade is lower than the flooding level. This type is used for classification of ore with flooding size between 0.83-0.15. Spiral classifiers are widely used in the distribution of ore in closed circuits with ball mills, grading ore and fine slit in gravity mills, grading granularity and flow of metal ore-dressing, and de-sliming and dehydrating in washing.

Overview

1) Introduction of spiral classifiers

Henan Zhongke Engineering & Technology Co., Ltd.

2) Classification of classifier

The spiral classifier mainly includes the single spiral classifier and double spiral classifier. According to the different depth immersed by the spiral blade of overflow, it has the following two kinds:

1. High weir type: the top of spiral blade upper than overflow surface and spiral center lower than overflow surface. Mainly used for the grading of minerals of overflow size 0.83-0.15mm.

2. Immersed type: spiral blade completely immersed below overflow surface. Mainly used for the grading of minerals of overflow size 0.15-0.07mm.

Explanation of model: like: “2FG-15”，in which, “2” indicates double spiral, no indication by the single spiral; “F” indicates the spiral classifier; “G” indicates high weir type, or “C” indicates immersed type; “15” indicates spiral diameter, unit dm.
