An 18’ dryer drum is not the only option. Rotary dryer drums as small as 4’ diameter can evaporate anywhere from 200 – 500-lbs/hr. Rotary drums much smaller than this have efficiency losses so an alternate drying system may be more beneficial. Using the same example above, with a product at 50% mcwb, a small rotary drum dryer can takeGet Price
Typically, drying systems include a rotary dryer consisting of a drum with a burner. Fly ash is fed into the rotary dryer, then discharged to a transfer conveyor for sorting and separation. The vapor from the process is pulled through a baghouse to remove fine particulates from the vapor streamGet Price
