    Abstract: A continuous mixer includes a barrel with a hollow interior, and a pair of mixing rotors housed in the barrel and that rotate in mutually different directions, each mixing rotor including a mixing portion with plural mixing flights formed about an axial center of the mixing rotor and projecting radially outward. The mixing rotors have a center distance therebetween smaller than a rotation outer diameter of each of the respective mixing flights. An inter-rotor clearance, which is the smallest clearance between the mixing portions at each rotation phase of the mixing rotors in a cross section perpendicular to axial directions of the both mixing rotors, has a dimension allowing an extensional flow to be generated in a material passing through the inter-rotor clearance. The continuous mixer can reliably and efficiently mix a material having a large viscosity difference between a dispersed phase and a matrix phase.

    Abstract: A water blending apparatus for use in conditioning foundry sand. The apparatus creates a vertical sand stream flow path which increases the surface area of the sand stream and allows water to be applied to both sides of the sand stream rather than a single side, as known with conventional water mixing apparatus. In addition, the blending apparatus includes a housing inside which a pair of mixers thoroughly mix the wetted sand. Because the mixers are not positioned in-line with the main sand processing flow, as in conventional apparatus, the mixing time is not dependent upon the speed of the conveyor, and therefore mixing time may be increased. Furthermore, the agitators positioned inside the housing have a more efficient active area since a smaller clearance space is required than with over-the-conveyor style mixing devices, which must avoid contact with the conveyor belt. As a result, the sand may be cooled more quickly due to increased initial water coverage.

    Abstract: A mixer apparatus is disclosed for mixing livestock feed and the like. The apparatus includes a container for the reception therein of the feed. The container includes a housing and a wall extending away from the housing, the wall defining an opening disposed remote from the housing for the reception therethrough of the feed. The arrangement is such that the housing and the wall define therebetween an enclosure for the feed received through the opening. An auger is disposed within the enclosure, the auger having an axis of rotation which extends through the housing. The auger includes a core and flighting connected to the core so that when the auger rotates, feed disposed within the enclosure is mixed. The flighting includes a first portion and a second portion staggered relative to the first portion such that movement of the feed between the first and second portions is interrupted.
