The classifier or spiral washer equipped with a ball mill as a closed cycle split ranging system is widely used by the dressing plant to distribute the mineral sand, or it is used by the gravity mill to grade ore and fine clay, to realize the size grading of ore pulp during the metal beneficiation process and to do desliming and dehydration during the ore washing process. The classifier has simple structure, reliable work, convenient operation, etc.
The classifier or screw washing machine has simple structure, reliable work, convenient operation, etc. Its working principle is as follows: as the different sizes and proportions of the solid particles lead to the different settling velocities in the liquid, the fine mineral particles floating in the water overflow and the coarse ones sink to the bottom.
The screw classifiers realize the mechanical classification by discharging from the screw into the upper part and grade and filter the material powder coming from the grinding mill, then send the blocks into the mill’s feeding hole by moving with the screw panel, and discharge the fine filtered materials out of the overflow pipe.
The base of the classifier is made of channel steel and its body is welded with steel plates. The flood peak and the spindle head of the screw shaft adopt a wear-resistant and durable pig iron cover, and the lifting devices can be electric and manual.
