High intensity blending tool with optimized risers for increased intensity when blending toners

A blending machine, comprising:

• (a) a chamber for holding a media to be blended;
• (b) a blending tool mounted inside the chamber, said blending tool comprising both (i) a shank having a long axle, at least one end, an end region proximate to the end, and a tip at the end of the shank;
• and (ii) a riser member fixedly mounted during rotation at the end region of the shank, said riser member having art outside surface with a forward region, wherein the forward region is angled outward from the long axis at an angle between 10 and 16 degrees:
• and
• (c) a rotatable drive shaft, connected to the blending tool inside of the vessel, for transmitting rotational motion to the blending tool such that tip speeds of the tool exceed 20 meters per second.

A blending machine comprising:

• (a) a chamber for holding a media to be blended;
• (b) a blending tool mounted inside the chamber, said blending tool comprising both (i) a shank of the tool having a long axis and a diagonal dimension, at least one end, and an end region proximate to the end and (ii) a riser member fixedly mounted during rotation at the end region of the shank, said riser member of the tool having a height dimension and an outside surface with a forward region, wherein the forward region is angled outward from the long axis at an angle between 10 and 16 degrees wherein the ratio of the height dimension to the diagonal dimension is greater than 0.20;
• and
• (c) a rotatable drive shaft, connected to the blending tool inside of the vessel, for transmitting rotational motion to the blending tool.
