Spiral classifier is also called screw classifier. The spiral classifier is widely used in the beneficiation plant to form a closed loop with the ball mill to split the ore or to classify the ore and fine mud, grade the slurry during the spiral classifier mineral processing, and dewater in …
Spiral concentrators are modem, high capacity, low cost units developed for the concentration of low grade ores. Spirals consist of a single or double helical sluice wrapped around a central support with a wash water channel and a series of concentrate take-off ports placed at regular intervals along the spiral (Figure 17).
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, tailings …
There are mainly four types of classifiers, namely high single spiral classifier, high- dual spiral classifier, sinking single spiral classifier and sinking dual spiral classifier. Features. Simple structure; Reliable operation; Convenient maintenance; Low cost; High efficiency; Operation.
In this study, a newly introduced compact enhanced gravity Closed Spiral Classifier (CSC) is tested experimentally for the classification of slurries containing silica or iron ore …
According to Table 4, the Cr 2 O 3 grade in spiral 1 feed is 24.16%, while Cr 2 O 3 grade of feed of spiral 2 is 9.62%, so it can be said that spiral 1 feed grade is approximately 2.5 times greater than that of spiral 2. This difference is due to the simultaneous classification and gravity separation function in the hydrosizer.
Compared with hydrocyclones, the outstanding advantages of spiral classifiers are: reliable work; easy to operate; stable grading area, fine overflow particle size can be obtained; large sink …
