Good quality sand spiral classifier machine working principle

1.Introduction of classifier 

The classifying ores  machine can be divided into the high weir classifier and immersed classifier according to the height of grading liquid surface. The high weir classifier is applicable for coarse-grained grading, size above 0.15mm, and the immersed classifier is applicable for fine-grained classification, size below 0.15mm. In addition, there is also a kind of low weir spiral classifier, the grading level lower than the spiral bearing on the bottom, with small liquid surface and large agitation, mainly used for the ore washing of mud-containing sand.

2.Application of classifier 

The classifying ores machine is widely used with a ball mill to make a closed-circuit circulation to classify the mineral sands, or to classify ore sand and fine silt in gravity mill. It is also applied to classifying granularities in metal mineral separation, or desliming and dewatering in ore washing. The classifier features simple structure, reliable and easy operation.

The spiral classifier mainly includes the single spiral classifier and double spiral classifier. According to the different depth immersed by the spiral blade of overflow, it has the following two kinds:
     1, High weir type: the top of spiral blade upper than overflow surface and spiral center lower than overflow surface. Mainly used for the grading of minerals of overflow size 0.83-0.15mm.
     2, Immersed type: spiral blade completely immersed below overflow surface. Mainly used for the grading of minerals of overflow size 0.15-0.07mm.

3.Working pricinple of classifier 

   Classifier equipment is by solid grain sizes, a proportion of different, so the fluid in settling velocity different principle, fine magnetic particles floating in the water, forming the overflow outflow, crude ores grain drowned in the bottom of the channel, the spiral into upper eduction, to conduct mechanical classification of a kind of classifying equipment, can put the mill inside machine grinded the pulp classification in filter, and then put the coarse material using spiral slice into grinding machine, the filter out the feeding port of fine material from the overflow pipe eduction.
