Spiral concentrators are gravity separators usually separating particle sizes between 0.1 and 2 mm in a water carrier medium1,2. The capacities of the spiral concentrators range between 1 and 3 t/h dry solids and recently in excess of 7 t/h in the case of high capacity spiral concentrators … Read More
Spiral concentrators are a gravity based concentrating device, that separates light density granular and sandy (18 mesh to 200 mesh (1 mm to 0.075 microns)) consistency material from heavier density material. In order to have a …
and spiral concentrators. Material in the size range 2 mm to 100 µm can be readily processed in spirals. In most gravity separators, the more closely size the material being processed, the more efficient the separation [10]. Sieves used for the test were arranged in a stack, with the coarsest
1. Introduction. Spiral concentrators are gravity based separation devices used for the preparation of coal, iron and other heavy minerals ores (Wills, 1992).The classification of the particles in spirals is based on the combination of gravity, centrifuge, drag and Bagnold forces (Atasoy and Spottiswood, 1995, Burt, 1984, Bouchard, 2001).The spirals operate on both …
Metso Outotec spiral concentrators are used in most applications, particularly for concentrating low-grade ores. Manufactured from lightweight, corrosion and abrasion-resistant materials, our spirals require minimal maintenance and …
Spiral concentrators have been widely used in coal preparation plants in Illinois and elsewhere to clean the 1 mm x 150 micron particle size fraction. The major factors which have made spiral ...

Our gravity concentration products separate fine heavy mineral sizes from 1.5 mm to 0.04 mm and are ideal for iron ore, chrome, mineral . get price
Typical spiral concentrators will use a slurry from about 20%-40% solids by weight, with a particle size somewhere between 1.5-.075 mm (17-340 mesh), though somewhat larger particle sizes are sometimes used. For good separation, the density difference between the heavy minerals and the light minerals in the feedstock should be at least 1 g/cm3 ...
Spiral concentrators are gravity separators usually separating particle sizes between 01 and 2 mm in a water carrier medium12 The capacities of the spiral concentrators range between 1 and 3 th dry solids and recently in excess of 7 th in the case of high capacity spiral concentrators when treating typical heavy mineral beach sands .
The fine coal DMC circuit is more forgiving than the spiral concentrators. "If the circuit is designed for 1 mm x 60 mesh, and the plant runs 2 mm through the circuit, it will eat it up," Bethell said. "It will handle oversize material with great efficiency." Size distribution of the feed is also important, especially for the TBS and ...
Spiral Concentrators. The spiral concentrator is a modern high-capacity and low-cost device It is developed for concentration of low-grade ores and industrial minerals in slurry form For coal concentration 6 turns providing a gentler slope with longer residence time for the more difficult separation The performance of spirals is dependent on a ...

Spiral concentrators from Multotec efficiently segregate mineral slurries by density and particle size in a range of mineral processing applications By using gravity and centrifugal force to create this separation spiral concentrators have very low energy requirements and no moving parts.
about 0.5 mm) where highly efficient dense-media processes predominate. For particle sizes in the range of about 1.0 mm down to about 0.1 mm that straddle the lower end of the intermediate size and the upper end of the fine size, recent improvements in the design of spiral concentrators and the re-engineering of
Heavy Mineral Spiral Concentrators Gravity separation of fine heavy minerals in the size range 1.5 to 0.04 mm may be conducted on spiral concentrators. Spiral plants may consist of multiple stage spirals, depending on the mineral being recovered and the product requirements. Multotec is a leading designer and manufacturer of spiral concentrators.
Spiral concentrators have been widely used in coal preparation plants in Illinois and elsewhere to clean 1 mm ×150 μm particle size coal fraction. The major factors which have made spiral concentrator so popular include its low capital and operating cost, no chemical reagent or dense medium requirement, and the ease of operation/maintenance.
The proven technology sorts different materials according to their density using the centrifugal flow. The lighter particles are thus flushed outward and the heavier particles inward. Our spirals are simple to install, are distinguished by their long service life and, as a static system with no moving parts, energy and…
