Classifier

lassifier Introduction

Our company independently manufactures this new generation series of the classifier, which synthesizes similar classification technology from Germany and Japan. At present it has reached the international advanced level of the same products. And it has advantages of simple structure , reliable and easy in operation. Now it is widely used in many areas, for example, it worked together with the ball mill, forming closed cycle to split and shunt the iron ore in the concentrating mill; classified the iron ore and fine silt in the gravity concentrator; graded the size of the pulp in metal processing and applied in de-sliming& dehydration operation during the process of ore washing. Actually, the classifier has four types: high weir single and double spiral, immersed single and double spiral classifiers.

High weir type : the top of the spiral vane is above the overflow surface, and the spiral center is under the overflow, mainly applied in classifying the size between 0.83-0.15mm.

Immersed type: the spiral vane all immersed under overflow surface, mainly applied in classifying the size between 0.15-0.07.

Working principle:

Classifier is mainly consists of driver , screw , trough , lifting device, bottom-support ( bearing bush ) and the discharging valve. The base adopts channel steel material, and the frame is welded with steel plate. Besides, the water input and spindle head of the screwing shaft use cast iron, making them durable and wear-resisting. Moreover, the lifting device has two types :motor-driven and hand-driven

Features and Benefit:

1. Large output, low energy consumption, high classifying efficiency

2. The granularity is concentrative distribution, high classification precision

3. Rational structure, fine applicability

4. A high degree of automation
