Description of double spiral classifier
The good quality double spiral classifier is the equipment that employed to eliminate the impurity which is inside of the sand ore materials, and it is also named stone double spiral classifier. The double spiral classifier own it's name by it's specially working principle. Most impurity eliminating process are using the water , eliminates the lightly dust materials by the flowing water , so it got it's name as double spiral classifier.In the series of double spiral classifier , there are types of : spiral double spiral classifier ;rotary double spiral classifier; water impeller double spiral classifier and vibrating double spiral classifier. All these double spiral classifiers have different look and the working principle, but all the washers widely used in the field of building industries; sand making industries ;precast yard ;Hydropower construction site .

Consist of spiral double spiral classifier
The double spiral classifier consist of cell body, speed reducer ,motor power ,central shaft, spiral scatters, support parts.Sentai Mining Factory is the real good producer of double spiral classifier,which has years experience of how to producing the quality double spiral classifier with stick steel plate . We can supply almost all the machine which connecting with beneficiation .

Advantage of Sentai double spiral classifier :
* This kind of double spiral classifier is slope slightly installed , it has highly efficiency of cleaning the sand materials .
* The double spiral classifier can handle the materials which size within 0-30mm ,it can eliminate the dust ,clay very quickly and totally .
* It is easy to operation and very easy to maintain. And it has low consumption .
* All kind of double spiral classifier made by quality steel plate with CE certifications .

Working principle of double spiral classifier
The double spiral classifier eliminate the impurities by the buoyancy of water ,as we all knew the specific gravity of various materials are different ,so when double spiral classifier on operation , the spiral scatters will rotating , the strength of rotating spiral scatters will push the water going forward , at the same time , the light specific gravity which is mean the impurities will flowing with water , but the clear sand mater will fell down and going forward also by the strength of spiral scatters .this the way how double spiral classifier doing .

Our main product double spiral classifier , :hammer crusher , rotary dryer ,ball mill ,magnetic separator ,flotation separator .
