  • Coal Slurry: an Idea that Came and Went WyoHistory.org

    Nov 14, 2014· During the coal boom of the 1970s, slurry pipelines were proposed as an alternative to rail transport. Coal would be crushed, then mixed with water to create a slurry and sent via pipeline to its destination, where the mixture was dried, then burned. When in the pipeline, the slurry moved along at a leisurely four miles an hour.

  • What Is a Coal Slurry? (with pictures)

    Jan 19, 2021· Coal slurry is a waste product of coal mining. Components in slurry come from the coal and the chemicals used in processing it. The washing or purifying process reduces pollution-causing contaminants in the coal, but these impurities then become part of the slurry. The composition of coal slurry varies depending on the coal and the processing

  • Effects of Particle Size Distribution and Packing

    void fraction of the coal powder beds is the porosity of particle bed when the voids of coal particle bed are filled with water. Void fraction of CWS was calculated by the following equation (Henterson, et.al, 1978). ε = V. s V. c (2) V. s. where ε, V. c, V. s . referred to as void fraction, volume of coal, and volume of slurry

  • Effect of coal particle size distribution, volume fraction

    Mar 15, 2004· It is desirable that a particular coal–water slurry has a high pulp solids percentage and a low viscosity value. The industrially expected value for the viscosity of a coal–water slurry, even though not absolute, is a Brookfield apparent viscosity of 1000 mPa s at 100 rpm [3],[4] .

  • Wet And Dry Grinding Rod Mill & Rod Coal Water Slurry Mill

    The rod mill, a tumbling mill characterized by the use of rods as grinding media, is used for grinding ores, coal/coke, and other materials for both wet and dry applications. The rod mill performs best when making products having a top size of 4 mesh to 16 mesh operating in open circuit, or as fine as 35 mesh operating in closed circuit with a

  • Coal slurry Wikipedia

    Ideally, coal slurry consists only of crushed coal and water, which can be efficiently separated. In practice, the separation is significantly costly due to the large amounts of water needed and wastewater generated by the process. Furthermore, the slurry consists also of very fine coal dust that results in a waste called blackwater.As blackwater cannot be purified by a water treatment plant
