Apparatus for continuously making a mixture of viscous material with solid material

An apparatus for continuously making a mixture of viscous material with solid material, which comprises;

• first and second rotatable members supported in position for rotation in the opposite directions with respect to each other and spaced a predetermined distance from each other to define a mixing gap therebetween;
• first supply means for supplying the viscous material and for generating zones of cascading flow of said viscous material, said zones of cascading flow of said viscous material being respectively downwardly oriented towards said first and second rotatable members, said cascading flow of said viscous material in said zones forming a viscous layer around said first and second rotatable members, said viscous layers on said first and second rotatable members adjoining to each other and subsequently entering said mixing gap as said first and second rotatable members are rotated in the opposite directions to each other;
• second supply means for supplying the solid material onto said viscous layers, said solid material after having been supplied onto said viscous layers being dragged into said mixing gap during rotation of said first and second rotatable members to mix with said viscous material as it pass through said mixing gap;
• and
• third and fourth rotatable members supported in position below said first and second rotatable members for rotation in the opposite directions to each other at a higher speed than any of said first and second rotatable members, said third and fourth rotatable members being respectively rotated in the same direction as said first and second rotatable members and spaced a predetermined distance from said respective first and second rotatable members, said third and fourth rotatable members acting to remove the viscous mixture, which has emerged from said mixing gap sticking in part to said first rotatable member and in part to said second rotatable member, off from said first and second rotatable members, said mixture which has been removed from said first and second rotatable members subsequently falling downwards by gravity and being then collected.
