Abstract
A mixing apparatus comprises first and second opposing mixing members rotatable relative to one another about an axis and which have facing surfaces which extend away from the axis and which define a mixing chamber therebetween. Means are provided for rotating at least one of the mixing members to provide relative rotation between the first and second mixing members in a first rotational direction. An array of mixing formations on at least one of said surfaces interact to mix material within the mixing chamber and are configured to propel material within the mixing chamber towards the axis. The number of mixing formations on at least one of the surfaces increases with radial distance from the axis.

A mixing apparatus comprising:
- first and second opposing mixing members rotatable relative to one another about an axis;
- said first and second mixing members having facing surfaces which extend away from the axis and which define a mixing chamber therebetween;
- means for rotating at least one of the mixing members to provide relative rotation between the first and second mixing members in a first rotational direction;
- an array of mixing formations on at least one of said surfaces which interact to mix material within the mixing chamber and which are configured to propel material within the mixing chamber towards the axis as the first and second members are relatively rotated in said first rotational direction;
- and
- wherein the number of mixing formations on at least one of the surfaces increases with radial distance from the axis.
A mixing apparatus comprising:
- first and second opposing mixing members rotatable relative to one another about an axis;
- said first and second mixing members having facing surfaces which extend away from the axis and which define a mixing chamber therebetween;
- means for rotating at least one of the mixing members to provide relative rotation between the first and second mixing members in a first rotational direction;
- an array of mixing formations on at least one of said surfaces which interact to mix material within the mixing chamber and which are configured to provide a net propulsion of material within the mixing chamber towards the axis as the first and second members are relatively rotated in said first rotational direction;
- and
- wherein an axial portion of at least one of the first and second mixing members is removable to permit discharge of material from the mixing chamber as the mixing members are rotated in said first rotational direction.
A method of mixing a material in a mixing apparatus comprising a mixing chamber defined between facing surfaces of first and second opposing mixing members which are relatively rotatable to one another about an axis, the facing surface of at least the first mixing member having an array of mixing formations which interact with the facing surface of the second mixing member to mix provide a net propulsion of material within the mixing chamber as the first and second mixing members are relatively rotated, the number of mixing formations on at least one of the surfaces increasing with radial distance from the axis, at least some of the mixing formations being configured to propel material within the mixing chamber towards or away from the axis dependent upon the direction of relative rotation of the first and second mixing members, the method comprising relatively rotating the first and second mixing members in a direction such that said mixing formations interact to propel material towards said axis.
