  • Coal Spontaneous Combustion – Marine Surveyor Information

    Jul 19, 2019 · This method helps distribute the coal evenly and thus avoids breakage and segregation of fine coal. Segregation of coal particles by size should be strenuously avoided, as it may allow more air to enter the pile and subsequent heating of finer sizes. The height of the coal pile is also important.

  • Dry beneficiation of fine coal using density-segregation ...

    We investigated the segregation of fine iron ore of sub-mm size with varying the air velocity, and found that there exists an optimum air velocity to maximize the segregation . Here, we applied the dry separation based on segregation to fine coal treatment. Fine coal of +150–500 μm in size was fluidized at various air velocities. 2.
