This classifiers are of the spiral and screw family. It is of interest that the Homestake, long a user of cones for dewatering and classifying, selected mechanical bowl classifiers for their new mill addition. In the Homestake's enlarged and rearranged plant are 10 cones of local make, 7 ft. in diameter and with 65-deg. sides.

The Closed Spiral Classifier (CSC) assembly consisted of a few turns of spiral with one inlet and two outlets. The spiral had a uniform rectangular cross section with a width of 2 cm and a height of 0.5 cm. The outer radius of curvature of spiral was 5 cm. The closed spiral classifier was 3D printed in modular components using …

Dewatering. Spiral classifiers are designed to settle and dewater relatively coarse particles from high volume, low percent solid volume streams. Flexibility in layout and mounting positions as well as high resistance in harsh, dusty and ambient conditions are key features that our products can deliver.

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 processing of Indian iron ore slime using fluidized bed classifier followed by hydrocyclone and slow speed spiral classifier envisaged that the concentrate quality of 62.5% Fe (T), 4.2% SiO 2, and 2.23% Al 2 O 3 could be recovered from the slime assaying 50.8% Fe (T), 11.86% SiO 2 and 9.84% Al 2 O 3 at a material yield of 30% [46]. The …

A Spiral Classifier is a machine that is primarily used to classify the slimes (fines) from a coarser, sandy sized material. It has an inclined trough with one or two spirals revolving slowly and free from touching the sides or …
