Working Principle. The motion of the spiral creates pool hindered settling in the bottom pool area, and the agitation of water keeps the fines suspending in the liquid, while the coarser particles settle on the spiral and be transported to the discharge which located at the top of the classifier. Then gravity flow or pumps are used to move the coarse material to the next stage in the …
Operation Method of Mineral Processing Equipment Spiral Classifier. 1. After the spiral body rotates, the slurry can be fed. 2. When the spiral body of mineral processing equipment spiral classifier is in working condition, in case of special failures such as jamming, overload, etc., the spiral body cannot be pressed into the slurry.
Spiral classifiers are often combined with ball mills to form a closed-circuit cycle to separate ore sands, or to classify ore sands and fine mud in mineral processing plants. It is also used for or washing clay sand, silica sand, …
The launder from ball mill discharge to the classifier should have a slope of about 1″ per ft. depending on fineness of grind and pulp density. The launder from sand discharge of the classifier to the ball mill scoop box should have a slope of from 4″ to 6″ per ft. Spiral/Screw Classifier Speed
Mineral processing spiral classifiers are used to classify the ore sand and the graininess of ore pulp in metal beneficiation and desliming, dewatering and other processes in ore-washing operations.
