Abstract
Abstract Mixing machine with a plate- or dish-shaped container for the material to be mixed. A rotating mixing tool is accommodated in the container so as to rotate about an axis eccentric to the axis of the container. The axis of the tool is forcibly caused to perform a relative movement in relation to the mixing plate. The mixing tool comprises a flat disc-like rotary element which is arranged at the free end of its shaft. Rods are arranged in the rotary element which are substantially parallel or inclined in relation to the shaft. For higher speeds a ring is secured at the free ends of the rods which keeps the rods in place in spite of large centrifugal forces.

Claims Analysis
Total Claims: 28
Claim 1
Independent Claim
152 words
A mixing machine comprising a container mounted for rotation, a mixing device mounted on a shaft having an axis of rotation spaced from the axis of rotation of said container, means for rotating said mixing device about its shaft, said mixing device having a flat, rotary element carried on said shaft and mixing elements carried by said flat rotary element, said mixing elements being in the form of longitudinally extending members projecting generally upwardly from said flat rotary element at circumferentially spaced locations disposed radially outwardly of said shaft, said flat rotary element and said mixing elements being disposed below the level of the material which is being mixed in the container, whereby rotation of said mixing device causes the material being mixed to flow generally axially adjacent to said shaft towards said flat rotary element and thence radially outwardly past said mixing element to provide a pumping effect on said material.
Claim 2
Dependent Claim
152 words
A mixing machine comprising a container mounted for rotation, a mixing device mounted on a shaft having an axis of rotation spaced from the axis of rotation of said container, means for rotating said mixing device about its shaft, said mixing device having a flat, rotary element carried on said shaft and mixing elements carried by said flat rotary element, said mixing elements being in the form of longitudinally extending members projecting generally upwardly from said flat rotary element at circumferentially spaced locations disposed radially outwardly of said shaft, said flat rotary element and said mixing elements being disposed below the level of the material which is being mixed in the container, whereby rotation of said mixing device causes the material being mixed to flow generally axially adjacent to said shaft towards said flat rotary element and thence radially outwardly past said mixing element to provide a pumping effect on said material.

A mixing machine according to claim 1 wherein said rotary element is circular and said mixing elements are secured to said rotary element at circumferentially spaced locations on a circle which is concentric to the axis of said shaft.
Claim 6
Dependent Claim
69 words
A mixing machine according to claim 1 wherein said mixing device further comprises a second generally flat rotary element axially spaced from the first mentioned flat rotary element, said rotary elements being connected to one another by said mixing elements, said second rotary element having a central opening through which said shaft passes with an annular space being provided between said shaft and the edges defining said central opening.
Claim 7
Dependent Claim
50 words
A mixing machine according to claim 1 further comprising a second mixing device in said container mounted for rotation about an axis spaced from the axis of rotation of said container, said second mixing device carrying mixing blades which pass over a discharge opening in the bottom of said container.
Claim 8
Dependent Claim
101 words
A mixing machine according to claim 1 wherein the axis of rotation of said container is disposed at an acute angle relative to a horizontal plane, said container being driven at a rotational speed which imparts to the constituents of the material being mixed a centrifugal force greater than the specific weight of said material, a deflecting means mounted in said container and operable to deflect the material as the latter is moved radially outwardly by centrifugal force and redirect said material radially inwardly such that a stream of mixed material is caused to flow along a chord through the container.
Claim 9
Dependent Claim
34 words
A mixing machine according to claim 1 wherein the axis of rotation of said container and the axis of rotation of said mixing device are disposed at an acute angle relative to one another.
