spiral classifier structure. Spiral Classifier Working Principle The grinded pulp is fed into a tank from the inlet in the middle of settlement region, and the slurry classification sedimentation area is under the inclined tank. The spiral with low-speed rotation stirs the slurry, so that the fine particles rise, and the coarse particles sink to the bottom of the tank.

Description: Spiral classifier is one of the most common beneficiation equipment. The application of spiral classifier is very wide. It can separate the different grades products. It can separate the lighter metal mineral particles from the heavier particles. It can separate out the fine particles and liquid from the coarse particles, and can ...

The spiral classifier is a commonly used equipment for mineral processing (sand washing). It is often paired with a ball mill to form a closed-circuit circulation to divert ore. It is also used in gravity concentrators to classify ore and fine mud, ore slurry in metal mineral processing processes, particle size classification, desliming, dehydration, and …

The reason is that hydrocyclone would change the position of final material discharge without pressure standard. The spiral classifier agitates the pulp by spiral low-speed rotation, ...

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 …

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.

DOVE Spiral Classifier, also referred to as Screw Classifier, or Spiral Mineral Separator, is highly efficient classifier designed for closed circuit wet classification and separation of the Slimes (Fines) from a sandy …
