Thermal Coal Drying And Beneficiation Systems

Vibrating Fluid Bed Dryers. Over the past 50 years, Carrier has built numerous vibrating fluid bed dryersfor coal processing applications. Vibrating fluid bed thermal dryers are typically used for coals with a larger size fraction (such as run-of-mine coal). Vibration significantly assists in the fluidization of sticky and or wet coals, and helps convey larger particles that may not fluidize well and tend to settle.
