Counter Flow Drum Mixer includes an elevated virgin aggregate inlet end and an opposite asphaltic product discharge end. A burner lies intermediate the ends and defines a combustion volume. Virgin aggregate and recycle material in the annular chamber is prevented from entering the combustion volume by the shape of the shield flights.
Counter Pressure Filling Machine contains a filling tube projecting into the pressed-on container and a signal emitter triggering a closing pulse for the liquid flow valve.
