Read MoreOct 10, 2016 A screw conveyor is designed to move material forward, generally with minimum possible power input. An ash conditioner is designed to put much more power in to shear and back mix the bulk material to ensure good mixing of the powder and water and achieve the required residense time. It is a piece of process equipment not a transfer device.
