Teetered Bed Separator（TBS)
The Teetered Bed Separator is a heavy-medium fluidized bed device designed for the separation of fine coal slimes, especially particles in the 0.15–3 mm range. It is widely used in modern coal preparation plants as a replacement for traditional equipment such as jigs and shaking tables. It is particularly suitable for the efficient separation of low-ash clean coal from high-ash tailings.
