Gravity Separation Of Coal

multigravity separator an alternate gravity concentrator,aug 01, 2007 the multi-gravity separator (mgs) is a novel piece of equipment for the separation of fine and ultra-fine minerals. however, the published literature does not demonstrate its use in the separation of coal fines. therefore, an attempt was made to study the effects of different process variables on the performance of an mgs for the beneficiation of coal fines. the results obtained from.spiral separator multotec,gravity separators for coal our single- and double-stage spiral separators are optimised for coal particles in the size range of 1 to 0.1 mm, providing enhanced coal washing for slurries. their compact, modular design provides flexibility when building or upgrading your plant..
