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.

Application. Spiral Classifier has been widely use in closed-circuit grinding operations and it can also be used for the classification of ore sand and slime in gravity beneficiation plants, for the size grading of slurry in …

1. Crushing section: Utilize coarse jaw crusher, fine jaw crusher and vibrating screen to form a closed crushing circuit, so as to make 200mm rock ore down to 20mm. 2. Grinding section: Utilize ball mill and spiral classifier to form closed grinding circuit, so as to achieve more than 90% discharging size 200mesh(0.074mm). 3.

The jaw crusher has been a staple of the hardrock mining industry since its invention. It is used as a primary crusher for all types of ores. ... The spiral classifier separates the shaker table tailings into fine and coarse fractions. The coarse material is directed back to the grinding circuit to liberate more value, and the fine material is ...

The spiral classifier rotates at a low speed through the spiral to stir the pulp to make the fine particles suspend to the top and overflow to the overflow weir. In contrast, the coarse particles sink to the bottom of the tank and are conveyed to the discharge port by the screw to be discharged as returned sand, while The hydrocyclone needs to ...
