Mineral Processing Equipment Spiral Classifier

Operation Method of Mineral Processing Equipment Spiral Classifier

1.After the spiral body rotates, the slurry can be fed.

2.When the spiral body of mineral processing equipment spiral classifier is in working condition, in case of special failures such as jamming, overload, etc., the spiral body cannot be pressed into the slurry. It is necessary to stop the machine immediately to lift the spiral body out of the slurry surface and open the ore valve to avoid blockage.

3. When restarting, the spiral body must be lowered to a certain position before turning the mineral processing equipment spiral classifier.

4. If it is necessary to stop mineral processing equipment spiral classifiers during operation, the material feeding should be stopped first, and the operation can be stopped only after the material grading is finished and there is no material in the spiral classifier.

How to Improve the Classification Efficiency

(1)The traditional discharging mode of mineral processing equipment spiral classifier is changed to adopt double side discharging, which shortens the movement path of ore particles in the spiral classifier, avoids the backflow of pulp, timely discharges the overflow of fine particles, and shortens the settling time.

(2)For the fine mineral particles that have settled to the bottom of the tank, a mixing device can be added at the lower end of the mineral processing equipment spiral classifier to bring it back to the pulp surface and discharge with the overflow, so as to reduce the fine inclusion in the grit and improve the efficiency.

(3) It can also be considered to change the traditional gravity settlement classification and add a new force field in the classification area, such as adding a cylinder screen on the upper part of the mineral processing equipment spiral classifier for secondary classification, which can improve the efficiency of the spiarl screw classifier.
