Beneficiation spiral classifier is one of the devices, spiral classifier with different proportion of solid particles, and thus the speed of sedimentation in a liquid of different principles, mechanical grading of a device. Can mill to grind the material powder level in the filter, and then the coarse material the use of screw rotary vane inlet into the mill, to filter out the fine material is discharged from the overflow pipe. Spiral classifier referred grader. Classifier mainly high weir single and double helices, sinking single and double helices four kinds of classifier.
The classifier is widely used in the processing plant closed loop with ball mills. Or the gravity concentrator grading ore and fine in the mud, and metal beneficiation process on slurry particle size grading, and washing operations in the mud, dehydration and other operations.
The classifier has a simple structure, reliable operation, easy to operate.
Classifier mainly high weir single and double helices, sinking single and double helices four kinds of classifier.
