For Beneficiation Coal Slury

After drying process, the water content of the coal slurry is greatly reduced, and the calorific value is increased, which improves the its value-in-use, and reduces the operating cost of the power plant. In addition, if the dried slime is briquetted by a briquette machine, it can fully burn to improve the boiler combustion efficiency, operation economy and reliability. In short, the coal slurry drying and briquetting is the best way to achieve the goal of turning waste into treasure.

Producing such low-ash and low-sulfur fuels for these applications requires complete or near-complete liberation of mineral matter from the coal. The coal, when mined, contains various amounts of sulfur and mineral or stone matter, and by mineral matter, it is intended to include ash as well as pyrites which also contain sulfur. For advanced applications, cleaning includes grinding the coal to small particle sizes, since it has been found that in the grinding operation, relatively clean coal is

It has also been recently found that heavy-liquid cyclone separators are useful in the beneficiation of coal. This has been found to be a satisfactory method of cleaning because clean coal is less dense than the mineral or rock associated with the coal. For instance, clean coal has a specific gravity in the area of about 1.2 to 1.3 whereas the minerals contained in the coal or with the coal have

If a heavy liquid having a specific gravity in the broad general range of greater than about 1.3 to about 1.8 is used as the separating medium in a cyclone, clean coal reports to the overflow and mineral matter reports to the underflow, thereby separating the lighter, cleaner coal from the heavier material having greater mineral or ash content.
