In the area of mineral processing, the activities centered around laboratory and plant level trails on innovative coal/mineral preparation equipment. These included Vorsyl separator, water only cyclone, Dyna Whirpool, air sparged hydro cyclone, multi gravity separator and tri flow separator .
The extent of coal cleaning is primarily dependent upon three core factors; (1) coal liberation, (2) coal washability, and (3) separator performance. The first factor has been dealt with in part 1.
Graded fly ash particles have many useful industrial applications due to its fineness and spherical shape. However, grading of fly ash in an industrial scale is a challenging task. The possibility of using hydrocyclones for this purpose has been demonstrated here based on carefully conducted laboratory experiments. The primary objective of this research is to study the effectiveness of a ...
Mar 01, 2003· In this context, the vorsyl separator, designed by the National Coal Board, UK, had been identified as an alternative centrifugal dense medium separator for treating coal. Laboratory studies conducted with the unit established the superiority of the process over DMC for treating Indian coals (Rao et al., 1998).
Vorsyl Separator Used in many coal preparation plants Treatment of small coal sizes up to about 50 mm at feed rates of up to 120t/h The feed to the separator consisting of de slimed raw coal with the separating medium of magnetite Material of specific gravity less than that of the medium passes into the clean coal outlet Heavier shale
Figure 6.1 FGX dry coal separator [Honaker (95)] The coal on which this technology has been applied is Laurasian coal, with low near density material and relatively easy separation of mineral matter (contamination, adventitious mineral matter) from the product coal. In South Africa, the CoalTech

evaluation and modelling. The coal samples used were obtained from two different density-based cleaning processes, a Vorsyl dense medium separator for treating an anthracite (TW) with a size fraction of 0.5-8.0 mm and a spiral concentrator for treating a bituminous coal (DH) with a size of less than 2 mm. Textural

Washery-II of West Bokaro, Tata Steel, India has eight cyclones in a bank treating medium coking coal in the size range of − 13 + 0.5 mm. A three-mode strategy was adopted for increasing the clean coal yield from the washeries. Efforts were made initially to determine the major performance indices that would be used for measuring the separation efficiency.
76-mm diameter dense-medium cyclone (DMC) and a Vorsyl separator (VS). It is observed that a clean coal having around 16% ash can be produced using both the cyclones if the variables are properly optimized. Further, it is observed that at the same ash level the yield of clean coal was 5%-6% more in VS than in DMC. It has

Feb 01, 1998· In India, a major portion of metallurgical coal is produced by the dense medium cyclone process. A Vorsyl separator, a centrifugal dense medium separator, is proposed as a possible alternate to the dense medium cyclone. Experiments were carried out in the laboratory on a 76-mm Vorsyl separator and a dense medium cyclone for treating the same coal.
