The dry separation methods for coal beneficiation have been regaining attention in the past decades. a number of improved or newly designed devices have been developed—one of them is a negative pressure pneumatic separator npps. the said method of separation is based on the differences in the physical properties between coal and gangue minerals, such as the grain density, size, and shape.Jun 01, 2003 this new technology applied to benefi- ciating 50-6 mm size coal has claimed widespread adoption in china. z dry beneficiation technology with vibrated air-dense medium fluidized bed for fine coal of size fraction 6-0 mm has given good experimental results.
Dry concentration in coal preparation has been used in the removal of clays and pyritic grains [13,14]. dry concentration technologies of coal include air jigging [15,16,17,18], air dense medium fluidized beds [19,20,21,22], and most recently sensor-based sorting techniques [11,23]. although the last example shows as a very promising option for pre-concentration stages, its application is still in the industrial drying machine.
