How to Choose Equipment: Spiral Classifier or Hydrocyclone?
The spiral classifier rotates at a low speed through the spiral to stir the pulp to make the fine particles suspend to the top and overflow to the overflow . In contrast, the coarse particles sink to the bottom of the tank and are conveyed to the discharge port by the screw to be discharged as returned sand, while The hydrocyclone needs to ...

Flotation Regulator: PH Regulators, Activators, Dispersants
The reason why lime inhibits pyrite is the formation of a hydrophilic film of Fe(OH)2 and Fe(OH)3 on the surface of the mineral. For pyrite inhibited by lime, sodium carbonate and copper sulfate can be used, or sulfuric acid can be added to adjust the pH of the pulp to 6-7, and the pyrite can be floated again. 2. Sodium Carbonate

Kaolin Washing Process and Machine
Spiral classifier to wash and remove impurities. In the raw kaolin ore, the particle size of quartz, feldspar, mica, and other impurities is relatively coarse, generally larger than 325 mesh. The kaolin has a finer particle size, mainly concentrated in -2μm. The spiral classifier can remove most of the quartz and feldspar coarse sand.
