Factors Affecting the Spiral Classifier Efficiency
The higher the overflow dam of the spiral classifier, the finer the classification particle size. In production, you can appropriately adjust the height of the spiral classifier overflow dam according to the requirements of grinding fineness. (3) Rotate Speed. The rotate speed affects the agitation strength and the ability to transport sand back.

The pulp density of the classifier overflow was maintained between 25 to 30 percent. Periodic screen analysis of the overflow showed that the ore delivered to the flotation circuit averaged 90 percent minus-100-mesh. ... Oxidation roasting of antimony sulfide forms volatile xide or nonvolatile tetroxide, depending on the temperature and ...
How-to-choose-spiral-classifier? | miningpedia
Low Dam Spiral Classifier. The overflow dam of the low dam type spiral classifier is often lower than the center of the overflow end bearing, so the area of the settlement area is too small, the overflow production capacity is too low, and the agitation of the spiral on the slurry surface is large, so in actual production only It is used for ...
Spiral Classifier
Submerged spiral classifier is suitable for fine particle classification, the maximum size of overflow is generally below 0.2mm. Working Principle Of Spiral Classifier The spiral classifier is based on the principle that the solid particles are different in size and specific gravity, so the settling speed in the liquid is different.
