Spiral Classifier

Spiral classifier is a common classification equipment in beneficiation area, mainly has high weir type single spiral and double spiral, submerged single spiral and double spiral classifier. High weir spiral classifier is suitable for the coarse grain grading, the grading overflow particle size is generally greater than 0.15mm, Submerged spiral classifier is suitable for fine particle grading, the grading overflow particle size is less than 0.15mm in general. Spiral classifier is widely used in ball mill in the concentrator and deserves to shunt mineral sand into a closed cycle process, or use to graded sand and fine mud in the gravity concentrator, and metal beneficiation process for the pulp particle size classification, and washing of desliming, dehydration and other operations.

Features and technology advantages

1.Simple structure, stable operation, safe and reliable;

2.The main spiral frame electric lifting device of the standard configuration, making the equipment operation and replacement of spare parts more easy.

3.Optimization design of the helical blade, making sure of spare parts to minimize loss.

Working principle

Spiral classifier is of mechanical classification equipment designed by the principle of the different solid grainsize and specific density owning the different sedimentation rates in the liquid, consequently the fine particles floating in the water overflow, coarse particles sinking on the bottom of the channel are spiraled to the upper to discharge. It can classifiedly filter the pulp from grinding mill, and then the coarse materials are fed into the mill inlet by spiral pieces, the fine materials are discharged from the overflow pipe.
