Dec 30, 2016· Bulk Density of Coal depends on Size.Grade or Quality and Moisture in Coal. In a laboratory, Bulk Density is measured by filling the Coal in an empty Vessel of size one Metre height,length and breadth. The nett weight of coal gives the bulk density of Coal measured in Kilogram per Cubic Metre.
The bulk density of coal depends on the specific type of coal. It can range from 40 to 58 pounds per cubic feet, or 641 to 929 kilograms per cubic meter. The three types of coal are anthracite coal, bituminous coal and lignite coal. Anthracite coal has a bulk density of 50 to 58 pounds per cubic feet, or 800 to 929 kilograms per cubic meter.
The specific gravity of coal, especially of high moisture bituminous coal, such as is found in Illinois, is not a fixed value. Coals of different types may have characteristically different specific gravities, and it is equally true that coals of the same type vary greatly in specific gravity.
SPECIFIC GRAVITY STUDIES OF ILLINOIS COAL 19 This loss of moisture explains the high values obtained for the spe- cific gravity after boiling because, although the loss of moisture causes a decrease in the weight in air, the weight in water is approximately the same, whether the coal is fresh or dry.
The Specific Gravity - SG - is a dimensionless unit defined as the ratio of density of the material to the density of water at a specified temperature. It is common to use the density of water at 4 o C (39 o F) as reference - at this point the density of water is at the highest.. Specific gravities - SG - for common solids and metals can be found in the table below:

Classification of Coal Classification of coal based on volatile matter and cooking power of clean material . Sponsored Links . Coal is a readily combustible rock containing more than 50 percent by weight of carbonaceous material formed from compaction and indurations of variously altered plant remains similar to those in peat.
The specific gravity of coal is important during coal cleaning because many of the common mineral impurities in coal have much higher specific gravity (density) than coal. For example, the specific gravity of pyrite (fool's gold), a common impurity in coal, and the main source of sulfur in coal…
(Blair, 1906) has been used to determine the "true specific gravity" of coal (Fieldner and Selvig, 1951; U.S.Bureau of Mines (USBM), 1967) and coke (ASTM, 198la). This pycnometer method uses distilled water that is mixed with the coal and boiled to wet the hydrophobic coal particles (Ettinger and Zhupakhina, 1960).
Specific gravity - digitalfire.com. A ceramic slurry with a specific gravity of 1.8 is thus 1.8 times heavier than water. The best way to measure specific gravity is to weigh a container and record its weight, then weigh the container full of water and full of the liquid of unknown specific gravity.
Coal, Anthracite solid weighs 1.506 gram per cubic centimeter or 1 506 kilogram per cubic meter, i.e. its density is equal to 1 506 kg/m³. In Imperial or US customary measurement system, the Coal, Anthracite solid density is equal to 94.02 pound per cubic foot [lb/ft³], or 0.8705 ounce per cubic inch [oz/inch³] .
Bulk Density Of Indonesian Coal ... SGS provides accurate, reliable specific gravity and bulk density determinations. The results generated help you make informed processing decisions at your mine or industrial site. Excellent Cases. bulk density of indonesian coal.
The specific gravity of all other materials are compared to water as a fraction heavier or fraction lighter density, no matter how small or large the fraction is. For example, ammonium nitrate has a specific gravity (sg) of 0.73 while dry ammonium sulphate has a sg of 1.13 (1130 kilograms/cubic meter).

Nov 09, 2007· specific gravity = 1.51 lbs/cu. ft. = 94 Coal, Anthracite, broken specific gravity = 1.11 lbs/cu. ft. = 69 I'm confused, how can the specific gravity change depending on the size of the coal, solid or broken? Specific gravity is mass divided by volume, i.e. it's independent of sample size. What am I missing? Top.
