Introduction to Spiral concentrator

Spiral classifier or spiral concentrator is one mining machine used for ore dressing production, which precipitated in the liquid at different speeds by means of the proportion of solid particles and which is a device of the mechanical grading.

The screw classifier can grind the material into the powder level in the filter, and then the coarse material can be discharged from the overflow tube of the spiral concentrator. The spiral classifiers is also referred as grader.

The Working Principle of Classifier

The screw classifier is relying on the different sizes, various specific gravity in order to reach the different theory of settling velocity in the liquid, which can cause the fine mineral particles floating in the water into over flow, and the coarse ore particles sinking into the bottom.

The base of the machine is made up of channel steel body made of welded steel plate. The main features of this machine is that the head is taking spiral shaft and the main part pieces of it is mainly using wear resistant and durable material, and there are two type of the listing devices including device electric and manual. 

The features of screw classifier

1. To sort of the separation of excessive powder separation mechanism in sand dry production process.

2. This screw classifier is used for the big or medium production line with dry type.

3. The powder percentage between 0.00--0.75mm can be adjusted of 2%-15%.

4. The powder quality can be easily controlled, and the granularity adjustment is easy, flexible and credible.

5. Lower maintenance ratio with the plate of tile.

6. Inverter control technology, operating more concise.
