Estimating tons of coal on a property Kentucky Geological ...

Because specific gravity varies with rank different ranks of coal have different conversion factors. Anthracite: specific gravity = 1.47 so the conversion factor is 2000 tons/acre-ft Bituminous: specific gravity = 1.32 which is 1800 tons/acre-ft Sub-bituminous: specific gravity = 1.30 which is 1770 tons/acre-ft Lignite: specific gravity = 1.29 which is 1750 tons/acre-ft

Density of Coal anthracite broken in 285 units and reference

Coal anthracite broken weighs 0.856187 gram per cubic centimeter or 856.187 kilogram per cubic meter i.e. density of coal anthracite broken is equal to 856.187 kg/m³. In Imperial or US customary measurement system the density is equal to 53.450008 pound per cubic foot [lb/ft³] or 0.4949075 ounce per cubic inch [oz/inch³] .

Coal Density - an overview | ScienceDirect Topics

Coal density should be determined from average specific gravity of various coal rank as in 1.29 for lignite coal 1.30 for subbituminous coal 1.32 for bituminous coal and 1.47 for anthracite and semianthracite coal. From: Coal and Coalbed Gas 2014. Download as PDF. About this page.

THE PREPARATION OF FINE ANTHRACITE COAL FOR USE IN FILTER PLANTS

In the case of the preparation of fine anthracite coal this specific gravity difference is approximately 0.5 of a point the coal having a specific gravity of 1.50 to 1.60 and the refuse having a specific gravity ranging from 1.85 to 2.00. The process is briefly this : The feed coal is fed into a pitched chute

Specific Gravity Of General Materials Table

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).

What Is the Bulk Density of Coal? - Reference.com

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.

Coal | Geoscience Australia

The term 'black coal' is used in Australia to refer to anthracite as well as bituminous and sub-bituminous coals (Table 3.7). Black coal is higher in energy and has lower moisture content than brown coal. Brown coal also called lignite is a low-ranked coal with high moisture content that is used mainly to generate electricity.

Austrialian Anthracite C&C - UNITECH

The coal has a specific gravity of 1.45. Compared with American anthracite coals which have a higher SG C & S Filter Coal requires a lower backwash rate for the same Effective Size. This permits a saving in backwash pump capacity and reduces the quantity of backwash water required.

Properties of Anthracite | Physical | Thermal

The streak of Anthracite is black whereas its fracture is conchoidal. Luster of Anthracite is the interaction of light with the surface of Anthracite. Luster of Anthracite is shiny. Anthracite cleavage is non-existent. The specific gravity of Anthracite is 1.1-1.4. Anthracite is opaque in nature whereas its toughness is not available.

Density/Specific Volume of Anthracite Grades | Coal News ...

Coal Anthracite solid 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?

Water Handbook - Filtration | SUEZ

Conventional gravity and pressure rapid filters operate downflow. The filter medium is usually a 15-30 in. deep bed of sand or anthracite. Single or multiple grades of sand or anthracite may be used. A large particle bed supports the filter media to prevent fine sand or anthracite from escaping into the underdrain system.
