As one of leaders of coal wash in spirals industry, SBM always seeks innovation & excellence.
Spiral coal washing plant is an industrial process that separates impurities from raw coal or classifies high-quality coal and inferior coal. The products produced after the coal washing process are gcenerally divided into vermiculite, medium coal, secondary clean coal, and grade A clean coal. By washing coal, coal transportation cost can be reduced and coal utilization can be improved. The

Coal preparation, or beneficiation, is a series of operations that remove mineral matter (i.e., ash) from coal.Preparation relies on different mechanical operations (not discussed in detail here) to perform the separation, such as size reduction, size classification, cleaning, dewatering and drying, waste disposal, and pollution control.

every coal processing plant in South Africa employs spirals to beneficiate fine coal. Although spirals are normally capable of yielding products of acceptable quality, there are some instances, especially in the case of the No. 4 Seam coal, where spirals cannot produce the required product quality. It then becomes more economical to discard the raw fine coal than to process it with spirals

Wash water spirals require the addition of water at various points down the spiral and therefore provide a "washing" of the concentrate, i.e., transporting away light gangue from the concentrate band. The design of the Outotec wash water spiral, and especially the wash water system, was developed to meet the needs of modern ore producers. The patented open wash water cup minimizes the

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 one unit, two or more starts are constructed around one central support. New spirals have been developed that do not use

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

The -10 mesh coal is deslimed at 100 mesh and then sized at 10 mesh x 100 mesh is processed in the spiral circuit to produce coking coal. The -100 mesh slimes and -60 mesh coal is then processed in the flotation circuit to produce coking coal. The cleaned coal is dried in centrifuges and a belt filter press. Coarse rejects are crushed and then recombined with the fine tailings for disposal to
