Abstract:
A continuous mixing apparatus for particulate materials comprising:a dynamic input mixing stage including a housing adapted to receive the particulate materials and first displacement means for moving the particulate materials toward and through an aperture in said housing;a transition tube coupled to said housing adjacent the aperture therein for receiving the particulate materials upon discharge through the housing aperture by said first displacement means; anda static output mixing stage coupled to said transition tube for receiving the particulate materials from said transition tube, said output mixing stage including a mixing tube coupled to a source of liquid for adding a liquid to the particulate materials in forming a slurry, second displacement means disposed in said mixing tube for displacing the particulate material and slurry along said mixing tube and discharging the slurry from the mixing tube, and a baffle assembly fixedly disposed within and along the length of said mixing tube for thoroughly mixing the particulate materials and the liquid in forming the slurry prior to discharge from said mixing tube wherein said transition tube and said mixing tube are coaxially aligned.
