Counter current direct heat rotary drum dryer for dewatering msw

Oct 04, 2021 The rotary drum dryer is an essential component of the rotary dryer. It is a large, rotating cylinder known as the drum shell. It processes gas flows or dries air through the drum in counter-current or co-current modes. In counter-current mode, the material moves in the opposite direction for processing gas, whereas, the material moves in the
