Spiral Classifier
This product is featured with simple structure, reliable working condition and convenient operation.
Spiral Classifier also can be called spiral separator,screw classifier or screw separator,is widely used in the concentrator and make up a closed-loop with ball mill.
We produce high weir type classifier, single and double spiral type classifier and immersed single and double spiral classifiers. Our spiral classifiers are widely used in the separation of ore in closed circuits with ball mills for the grading of ores and metal ore-dressing and other operations.
This product is featured with simple structure, reliable working condition and convenient operation. Because different grains have different specific gravity and sedimentation rates in liquid, this product allows the fine ore to float in the water, while coarse ore sinks to the bottom.
1. Can be very convenient to control the content of sand powder and to meet users’ requirements.
2. Spiral classifier has advanced technology, simple process, particularly suitable for large and medium-sized sand making production line.
3. The content of powder with size of 0.00--0.75mm is between 2%-15% and can be adjusted.
4. The quality of powder is easy to control. The adjustment of fine is convenient, flexible, and reliable.
The principle used in spiral classifier is that different sizes of crushers have different weights, so their sedimentation rates are also different. In the working process, fine ore grains float on the surface of water, and rough grains sink on the bottom of the cell. Screw grader can classify materials from mill, and then bring the rough grains to the entrance mouth of mill with the help of flights, and discharge the fine ore grins though pipe. The pedestal spiral classifier is made of box iron. The body is made of welding steel plates. The faucet and spindle nose of screw shaft are made of pig iron set which is wear-resisting durable. The take-up sets include two types power-driven and manual operation.
