Spiral classifiers. A typical spiral classifier is shown in Fig. 1. The geometry of a spiral is characterized by the length or number of turns, the diameter, the pitch and the shape of the trough (Burt, 1984). The spiral feed is a mixture of water and ground particles that is gravity fed at the top of the spiral.

The spiral classifier is widely used to pregrading and inspection grading in closed circuits when used in the production flow of metal processing. According to the difference in sedimentation rate of mineral particles and mud, the particle sizes of ores with 1.5mm-0.03mm are classified. Classification equipment---the spiral of overflow end is …

However, slow the spiral speed down as much as possible for the classifier used in the second-stage grinding or fine-grinding cycle. In summary, lower rotational speeds are generally used in spiral classifiers, especially for large spiral classifiers. For example, to obtain coarse overflow, the speed of a spiral with a diameter of two meters ...

The overflow position of the high type spiral classifier is usually higher than the bearing center at the lower end of the screw shaft, and lower than the upper edge of the overflow end spiral, so the area of the settlement area is larger than that of the low type spiral classifier, and the height is also higher.

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.

Spiral classifier uses the principle of the proportion different of solid particles, so the precipitation speeds is also different in the liquid. Fine mineral particles float in the water and overflow; the coarse ore particles settle on the bottom of the channel. Material is discharged from the upper by spiral, so as to finish the grading work.
