Spiral Classifier. Spiral classifier is used for material classification with spirals used to stir and convey materials according to the difference in material settling velocities. It is a kind of gravitational and hydraulic classifiers. The specification of spiral classifiers is represented by the number and diameter of spirals.

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 sized (Coarse) material. It is well suited for classification, where a two product size-split is required. Due to inherent operational qualities, DOVE …

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, also known as the classifier or horizontal spiral classifier, is a type of equipment used in ore processing plants. It is used for mechanical classification based on the principle that solid particles have different specific gravities and therefore precipitate at different rates in a liquid.

Major portions of this have been excerpted from A Mining Engineers Notebook: Mineral processing (1). Previously I have presented an over view of Physical Separation vs Froth Flotation vs ...

3) Submerged spiral classifier. The overflow end of submersible spiral classifier is usually equipped with 4-5 spiral blades, all of which are immersed under the liquid level in the settling area, so the …

The shape of the spiral classifier is a rectangular chute with an inclination angle of 12°- 18.5°. The bottom is semicircular, and one or two longitudinal shafts are installed in the groove. The spiral blades are continuously arranged along the shaft length, and the spiral shaft is driven to rotate by the upper end transmission mechanism.

3.3 Spiral concentrators : Of the gravity separation processes, the spi ral concentrators and circular jigs are tw o of the most . economical due to their simplicity and use of space.

Compared with these two classifiers, the hydrocyclone has a better classification effect when processing finer-grained materials (the separation particle size range is generally 0.3-0.01mm). 2. Floor area. Obviously, the footprint of the hydrocyclone is significantly smaller than that of the spiral classifier.

Zigzag classifiers for separation of ferruginous. Matsukawa Yasutsugu designed an inertial air. classifier separating the fine and coarse particles. by utilising electrostatic fields applying to ...

It is obvious that the floor area of hydrocyclone is significantly smaller than that of the spiral classifier. Usually, the hydrocyclone covers an area of only l/30 to l/50 to the spiral classifier. The equipment floor area requirement also limits the application of the spiral classifier to a certain extent. 3. Classification Efficiency.
