Gravity Spiral Concentrator Working Principle

The processes involved in mineral concentration by spirals are similar for all models. As feed containing 25-35% solids by volume is fed into the channel, minerals immediately begin to settle and classify. Particles with the greatest specific gravity rapidly settle to the bottom of the spiral and form a

Spiral Classifier for Mineral Processing

In Mineral Processing, the SPIRAL Classifier on the other hand is rotated through the ore. It doesn’t lift out of the slurry but is revolved through it. The direction of rotation causes the slurry to be pulled up the inclined bed of the classifier in much the same manner as the rakes do.

Introduction to Mineral Processing or Beneficiation

Spiral concentrators are modern, high capacity, low cost units developed for the concentration of low grade ores and industrial minerals. Spirals consist of a single or double helical conduit or sluice wrapped around a central collection column with a wash water channel and a series of concentrate removal ports placed at regular intervals along the spiral.

Spiral Classifier for Mineral Processing Fote

The spiral classifier works by virtue of the principle that the size and specific gravity of solid particles are different, so the sedimentation rate in liquid is different. Fine ore particles float in the water and overflow, while coarse ore particles sink at the bottom of the tank and are discharged by spiraling upward to perform mechanical classification.

Spiral Classifier goldcilplant

Working Principle With the aid of the principle that the solid particle size is different and the specific gravity is different, the settling velocity of solid in the slurry is different. The fine solid is discharged at the overflow weir，and the coarse particles sink to the bottom, driven by the spiral and discharge from the upper end of the classifier.

Common Types of Spiral Classifier Used in the Mineral

Here is mainly introduce common types of spiral classifier used in mineral processing according to two aspects. The height of overflow weir. The number of screw shift. Let's dive right in! In mineral processing, the ores need to be grinded into a certain size that the fine-grained useful minerals and gangue minerals achieve full dissociation.

Spiral Concentrators — IMSC Group

Principle of Separation. Spiral separation is based on the specific gravity difference present in a feed mineral suite. When fed a dilute pulp mixture of minerals of different specific gravities, the lighter minerals are more readily suspended by the water and attain relatively high tangential velocities so that they climb toward the outer rim of the spiral trough.

Mineral processing can involve four general types of unit operation: comminution particle size reduction; sizing separation of particle sizes by screening or classification; concentration by taking advantage of physical and surface chemical properties; and dewatering solid/liquid separation.

Fine mineral particles float in the water and overflow; the coarse ore particles settle on the bottom of the channel. Material is discharged from the upper by spiral, so as to finish the grading work.
