Outotec Spiral Concentrators are all wear-resistant polyurethane/fiberglass construction helices. Each spiral is supplied complete with detachable feed and product discharge boxes of solid cast polyurethane. The product box will simultaneously collect product middlings and
Spiral separators of the wet type, also called spiral concentrators, are devices to separate solid components in a slurry, based upon a combination of the solid particle density as well as the particle's hydrodynamic properties (e.g. drag). The device consists of a tower, around which is wound a sluice, from which slots or channels are placed in the base of the sluice to extract solid particles that have come out of suspension.

Circuit analysis can be used to evaluate the overall effectiveness of various configurations of unit operations in mineral and coal processing circuits. This powerful tool, has regretfully seen only limited application in the analysis of coal processing circuits. Strictly speaking, this method can only be applied if particle-particle interactions do not influence the probability that a

The different stages of the mechanism of concentration in spiral concentrators are discussed. The significance of many design and operational variables and their interrelationships are examined. The various areas where the spiral concentrators are applicable are presented.
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.
Gold spiral concentrator Working Principle Gold spiral concentrator is to Use physics and a precisely designed piece of equipment, the material is discharged onto a banked metal flight which is spirally wound around a central shaft. As the material flows down the separator, its speed increases, and centrifugal force carries it toward the outer
Spiral §1. 1 Spiral A spiral concentrator uses gravity to separate particles of different densities. It is used globally in the mineral processing industry. It is one of the most effective, low-cost devices for the gravity beneficiation of ores.
Spiral concentrators are normally used in banks of multiple spirals. Typical capacities for spirals run from 1-3 tons per hour of feed for minerals and 3-5 tons per hour for coal. Typical construction of a spiral concentrator is fiberglass and urethane to reduce wear from abrasion.
Spiral concentrators are compact, cost-effective and generally efficient gravity concentration separators for a wide range of applications (for example, coal, beach sands, iron ore, chromite and tantalite). Recent research has resulted in the development of mathematical models to predict the performance of spiral concentrators

Our Australian based head office houses the world's largest spiral manufacturing facility and produces over 20,000 starts annually. In 2010/11, we manufactured HC33 and WW6 spirals for ArcelorMittal's Mont Wright mining operations in Canada to deliver the largest single spiral order in our history. Spiral Concentrators. Features

principle of spiral concentrator has been discussed in the literature.[9–11] The main process variables of a typical spiral concentrator are the feed flow rate, feed pulp density and the splitter position.[9, 11–13] In the present investigation, the experiments were carried out with an objective to develop the
16.6.3 Spiral Concentrator. The spiral concentrator first appeared as a production unit in 1943 in the form of the Humphrey Spiral for the separation of chrome-bearing sands in Oregon. By the 1950s, spirals were the standard primary wet gravity separation unit in the Australian mineral sands industry.
