Spiral Concentrators. Single Start Spiral. 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 good separation, there should be a difference in SG's of at least 1.0.
Dec 15, 2005 A study was conducted to determine the sulfur reduction attainable by washing fine-size coal on a spiral concentrator. Crushed samples of Middle Kittanning and Bakerstown bed coals washed on the spiral provided pyritic sulfur reductions of up to 90 percent for the plus 200-mesh material.

Introduction to Spiral concentrator. Spiral classifier or spiral concentrator is one mining machine used for ore dressing production, which precipitated in the liquid at different speeds by means of the proportion of solid particles and which is a device of the mechanical grading.
Erdong Wu. Spiral separators and dense-medium cyclones (DMCs) are widely used for separation of −1 + 0.125 mm fine coal. In this study, testing was carried out using −1 + 0.125 mm fine coal.
A spiral concentrator (1) comprising a spiral trough (2) mounted on a central column (3) which is characterized therein that, in comparison with a conventional trough having a profile (11) which is generally concave and which slants downwardly from an outer edge of the trough towards a central column, the profile (8) of the trough is deepened in a section of the trough adjacent the central.

The spiral concentrator is one of the most effective, low-cost devices for the gravity beneficiation of ores. Manufactured from lightweight, corrosion and abrasion resistant materials, spirals require a minimum of maintenance and upkeep. Spiral concentrators offer a relatively simple unit operation that translates to low capital and operating cost.
The latter in referred to as a dry spiral concentrator and the former is a wet spiral concentrator (Mine-Engineer, 2015). 2.1.1 Wet Spiral Concentrators Wash-Waterless Spirals These types of spirals are the most common in industry today. They are especially used for the concentration of low-grade ores.
Spiral classifier is widely used in beneficiation plant to match with ball mill to form a closed circuit circulation path to distribute ore sand. Filter the material powder milled in the mill, and then use the spiral piece to screw the coarse material into the ball mill inlet, and the filtered fine material is discharged from the overflow pipe.
The twisting open trough geometry of spiral concentrators is illustrated in Figure 1. Employed in the fine coal and heavy mineral processing industries, a slurry mix of fine (75 - 3000 m) particles and water is fed to the top of the concentrator. As it gravitates downward, light suspended particles migrate outward by the centrifugal force whilst.
The benefits of using the FM1 spiral for the treatment of fine grained silica sand, tin tailings, iron ore and copper were also investigated (Richards et al 2000). Other potential applications for the use of fine spiral technology include operations that currently grind their feed material to 80 passing 75 m to achieve satisfactory liberation.
