  • ACARP the Classifier™ improves recovery of fines

    Traditionally coal preparation plants in Australia have had issues with the processing of fine coal. Typical dense medium cyclone (DMC)/spirals thermal plants have discarded tailings fines less than 150 microns. Coking coal plants with only DMC and flotation have lost yield of the higher size

  • Dynamic classifiers: a fine way to help achieve lower ...

    08.04.2004  In the UK, the majority of coal mills on existing power plants are fitted with static classifiers and improvements to these offer a limited means of improving the fineness of the ground product from the coal mills. A better solution is to exchange the static classifier for a dynamic (or "rotary") type. And the latest generation of dynamic classifiers is indeed proving to be a good way of ...

  • Optimal coal processing route for the J 0.5 mm size fraction?

    Optimal coal processing route for the 3 x 0.5 mm size fraction? One can see from the data that the separation efficiency achieved on the fine size fractions is somewhat impaired, compared to the efficiency of separation of the coarser size ranges. The recovery efficiency is, however, still superior to some water-only processes.

  • Gravity Separation and Desliming of Fine Coal: Pilot

    The first Reflux Classifier performed a density separation that produced a coal product contaminated with fine high-ash slimes. This was then washed in the second Reflux Classifier to remove the fine clays and mineral matter. This combination reliably produced a clean coal product and allowed gravity separation performance to be extended from the usual eight-fold limit of upper to lower size ...

  • Coal - Wikipedia

    Cannel coal (sometimes called "candle coal") is a variety of fine-grained, high-rank coal with significant hydrogen content, which consists primarily of liptinite. There are several international standards for coal. The classification of coal is generally based on the content of volatiles. However the most important distinction is between thermal coal (also known as steam coal), which is burnt ...
