Spiral Classifier 

1.  Spiral Classifier

Spiral classifier mainly high weir single and double helices, sinking single and double helices four kinds of classifier.

Product structure:grading machine consists of gear, spirochetes, tank, lifting mechanism, the lower bearing (bearing) and discharging valve. The classifier is widely used in the concentrator with ball mills closed circuits Cheng shunt mineral sands, or the gravity concentrator grading ore and fine in the mud, and metal beneficiation process on slurry particle size classification.

2. Application of   Spiral Classifier

Spiral Classifier is widely used in mineral processing plant to match with the ball mill and form a closed-circuit circulation to process mining sand, or used in gravity mine-selection plant for classifying sand and mine mud, and grading sand according to the particle size, disliming, dewatering in the mine washing process. FG series Spiral Classifier has simple structure, reliable operation, convenient operation,etc. The spiral classifier is a kind of classifying machine that adopts the principle of settling speed difference according to different material sizes and specific gravity. fine particles floating in the water overflow out; the coarse ore grain sinks to the bottom of the chase which will be pulled to the upper by the spiral and discharging out.

3.operating principle of Spiral Classifier     

 Spiral classifier is by means of solid particles of different sizes, the proportion of different, thus settling velocity in liquids of different principles, fine mineral particles floating in the water to overflow out of coarse mineral particles sink to the bottom. Discharged from the screw into the upper part, to a hierarchical classification of mechanical equipment, can mill to grind the material powder level in the filter, and then use the coarse material helical screw rotary vane into the mill feed, the filter out the fine material is discharged from the overflow pipe. The machine base is made of channel steel body with steel plates welded together. Into the head of the screw shaft, shaft, using pig iron, wear-resistant and durable, lifting devices of electric and manual.
