Energy Saving Good Quality double spiral stone washer machine

Introduction

There are four types of classifiers, high weir type single and double spiral classifier, immersed single and double spiral classifier.Spiral classifier (Screw classifier) is widely used for distributing ore in the close circuit with ball mill, grading ore and fine slit in the gravity mill, grading granularity in the flow of metal ore-dressing and desliming and dehydrating in the washing.

Working principle 

Classifier is equipment using the theory that different gravels have different specific gravity and sedimentation rates in liquid to do the classifying work. The equipment allows the fine ore to float in the water, while coarse ore sinks to the bottom, then the coarse materials are sent to the feeding mouth, and the fine materials are discharged. Classifier often used after ball mill. It can filter the output grinded by ball mill hierarchically, and send the rough material into the ball mill by spiral and discharge the fine one from the overflow tube.

Features

1. It is used for excessive powder separation in dry type sand production line, and it is very convenient to control powder content to meet users' requirements.

2. It is suitable for medium-sized dry type sand making production line.

3. The powder (0.00-0.75 mm) content can be adjusted between 2% -15%.

4. Powder quality is easy to control, and fine adjustment is convenient, flexible and reliable.

5. It uses tile lining, so repair rate is very low.

6. The inverter control technology makes operation more concise.
