Rotary Continuous Mixer shown with ASME-code high pressure jacket for heating or cooling with water, steam or oil.
Solid "weirs" at the discharge end of the mixing drum function as a "dam" to build a "residence volume" of material before it overflows the weir. For applications requiring complete clean-out, an optional "discharging weir" (shown) scoops remaining material from the drum when its rotation is reversed.
