The height H of the overflow of the high spiral classifier is 1/4-3/8 of the spiral diameter D, which is mainly used for ore classification with an overflow particle size of 0.83-0.15mm. The H of the submerged spiral classifier is 3/4-1 of D. It is mainly suitable for ore classification with an overflow particle size of 0.15-0.07mm. 3.
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 ...

Jul 01, 2019 classifying machine /high ore spiral classifier for Spiral classifier is a type of classifying machine that classifies materials based the principle that the solid particles with different sizes and proportions have different falling speed in the liquid, and fine ore particles float in the water and coarse ore particles sink ...
The high wire spiral classifier is applied in the classification of ore with particle size 0.83-0.15mm. Working Principle. The grinded pulp is fed into tank from the inlet in the middle of settlement region, and the slurry classification sedimentation area is under the inclined tank. ... High spiral classifier as the ancillary equipment of ...
According to the size of classification area, it can be classified as submerged type, high- type, and low- type. (1) The spiral blades at the lower end of the submerged spiral classifier are all immersed in the pulp with the largest classification area, which is applicable to the processing of fine materials. (2) The spiral blades at ...
Maintain Proper And Uniform Ore Feeding When the pulp concentration is constant, if the ore fed into the classifier increases, the flow rate of the pulp also increases, resulting in a coarser particle size of the overflow product. ... High spiral classifiers are usually applied to classification of coarse-grain particles, generally with ...
Experiments were carried out using a spiral concentrator test rig containing feed conditioner, centrifugal pump and a spiral concentrator with feed to spiral and recirculation. Time samples of concentrate and tails were collected, weighed, dried analysed. Regression equations were developed for Concentrate yield, grade and …
