Abstract:
A rheometer for assessing characteristics of materials, the rheometer comprising:a vessel (5, 25) for containing a material (7, 27), the characteristics of which are to be assessed;means (6, 26) disposed in use within the vessel for passing through a material to be assessed; andthe vessel (5, 25) and the means (6, 26) disposed therewith in being constructed and adapted so as to be simultaneously:rotatable relative to each other about an axis, andmovable in the axial direction relative to each other,wherein means (3, 23) is provided for determining rotational forces as a result of said relative motion in order to assess the characteristics of material (7, 27) within the vessel (5, 25) and wherein the means (6, 26) disposed within the vessel comprises rotor means in the form of a plurality of blades extending substantially radially from a rotor shaft and disposed at an angle relative to the axis of the shaft.
