KREBS® Coal Spirals for fine coal cleaning - …
Spiral coal concentrators use the specific gravity of materials with different densities to separate coal, and produce a low-ash coal product at high efficiency. Our high-performance Coal Spirals deliver a feed capacity of 2 STPH to 3 STPH (1.8 mtph to 2.7 mtph) per start, dependent on raw coal quality and refuse amount to be discarded. Optimum spiral feed size is -1 mm to 0.15 mm (14 M x 100 …
Spiral Concentrators - Mine Engineer.Com
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 moved, unless …
Spiral Concentrator - Outotec
Coal; Mica; Washwaterless spirals. This type of spiral is used in most applications, particularly for concentrating low-grade ores. The only water required is added with the solids prior to introducing feed onto the spiral. Concentrates are removed either at the bottom directly into the product box or at several intermediate take-off points down the spiral.

Gravity Spiral Concentrator Working Principle
Spiral Concentrator. Spiral concentrators are modem, high capacity, low cost units developed for the concentration of low grade ores. Spirals consist of a single or double helical sluice wrapped around a central support with a wash water channel and a series of concentrate take-off ports placed at regular intervals along the spiral (Figure 17). To increase the amount of material that can be processed by …
Evaluate Spiral Concentrator Circuit Performance
The clean coal streams from both spirals are combined to produce an overall clean product, while both reject streams are discarded. The circuit is normally configured so that no cleaner middlings are produced and no products are recycled. Surprisingly, circuit analysis indicates that this configuration is no more efficient than a single-stage unit. In fact, no improvement in efficiency is obtained even when …
COAL BENEFICIATION - cmpdi
Spiral Concentrator and Slurry Jig A research project was undertaken by CMPDI in association with CCL to optimize the recovery of clean coal by use of slurry jig and spiral concentrator . A pilot plant with slurry jig and spiral concentrator was installed at Rajrappa W ashery . At the washery Œ16mm coal was treated in small coal Batac Non-Coking Coal

Compound spirals offer better performance in a more efficient configuration. Prep plant operators in the US are increasingly opting to use spiral concentrators. They are easy to install, operate and maintain but their downfall is low capacity. The article describes spirals available from PrepTech/Multotec, Krebs Engineers and Roche MT.
