· The gravity spiral circuit is designed to extract and concentrate "coarse gold' from the recirculating load in the mill grinding circuit and hence prevent a build up within that circuit and the eventual escape of some of that gold into the tanks and thereon into the final tails. (See fig. 4) Optimum Operating Conditions of a Spiral Concentrator. For the spirals to work efficiently ...
KREBS#174; Coal Spirals for fine coal cleaning FL. Spiral coal concentrators use the specific gravity of materials with different densities to separate coal, and produce a lowash coal product at high efficiency. Our highperformance Coal Spirals deliver a feed capacity of 2 STPH to 3 STPH ( mtph to mtph) per start, dependent on raw coal quality and refuse amount to be ...
The spiral models each have different combinations and have been developed to suit the coal quality. New research and development has shown that our compact, modular designs have added flexibility when building or replacing spiral plants. This results in processing solutions that extend the life of your plant and reduce overall maintenance costs.
Coal spirals are widely used in coal preparation plants in Illinois and around the world to clean fine coal, typically in the 1 x mm size range. Despite their popularity and the trend toward ...

· Spiral separators, sometimes known as "coal spirals", are used in the coal industry to beneficiate raw coal to a product having a higher heating value and a lower sulfur content. The coal particles are mixed with water to form a slurry which is fed by gravity through a helical trough which is commonly referred to as a "helix". Such troughs typically make 5 turns about a vertical axis and have ...
· For many operations, runofmine coal consists of a composite mixture of carboniferous material and various noncoal impurities, such as rock, shale, clay, and water. Coal preparation, also denoted washing, cleaning, processing or beneficiation, is the stage where invaluable impurities are physically separated from the coal material in order to satisfy the specifiions set by a given coal ...
Multotec has designed and optimised the double stage MX7 coal spiral concentrators to process feed with a size range of mm to mm for difficulttowash coal. The 2stage spirals, the SX7 and MX7, incorporate two stages of spiralling into a single spiral assembly, reducing plant height and floor space requirements – ultimately reducing capital and operating costs.

Some spiral concentrators, especially those used in coal cleaning, have the capability of removing the high density material at multiple positions in the vertical spiral. Coal can consist of as much as 50% high density material, compared to a typical heavy mineral with only 5% to 10% high density content. These cutter bars are adjustable, and are usually set up during the start up and rarely ...
A study of coal washing spiral operation and performance is under way at the JKMRC. The program has two components—a pilot plant study, and sampling programs conducted in operating washeries. The objective is to use the pilot plant data to develop a fundamental understanding of the spiral separation process, and to formulate a model of spiral performance which can be subsequently validated ...
coal and produce metallurgical coal or power station coal. The objective of the DMS plant operation is to produce coal product within a minimum quality specifiion and maximum possible yield (England et al., 2002). Meyer and Craig (2010) have indied that coal DMS plants do not typically operate at steady state and that setpoint changes should be tracked appropriately in terms of ash ...
