1.9t Single or Double Sand Screw Classifier Introduction ofSand Screw Classifier Screw classifieralso called spiral classifier, is one of beneficiation equipment. Spiral Classifier can be divided into single and doublescrew classifier. Sand Screw Classifier is widely used in the distribution of ore inclosed circuit with ball mill in mining processing, in order to get a certaindegree fineness of ore particles, meanwhile increasing the efficiency ofgrinding. The Mining Spiral Classifier can also be used to wash sand and play otherfunctions. Features ofSand Screw Classifier 1. Can bevery convenient to control the content of sand powder and to meet users`requirements. 2. Spiralclassifier has advanced technology, simple process, particularly suitable forlarge and medium-sized sand making production line. 3. Thecontent of powder with size of 0.00--0.75mm is between 2%-15% and can beadjusted. 4. Thequality of powder is easy to control. The adjustment of fine is convenient, flexibleand reliable. 5. Tilelining, repair rate is very low. 6. Adoptingvariable frequency control technology, so operating is more concise.
