Abstract
An improved blending tool with an enlarged collision profile and method of use by rotation in a blending machine. The improved blending tool comprises an enlarged collision surface fixed at the end of the tool's center shank wherein at least half of the trailing surface of the collision surface is negatively sloped.
Claims17
A method of making toners, comprising
- (a) melt-mixing a mixture containing toner resin and colorants;
- (b) reducing the melt-mixture into particles;
- (c) adding surface additive particles to the mixture of melt-mixture particles;
- and
- (d) blending the melt-mixture particles and surface additive particles in a blending machine using a rotating blending tool rotating in a plane, said rotating blending tool comprising a center shank having an end and a region proximate to the end;
- an enlarged collision element rigidly fixed during rotation of the tool to the center shank at the end region;
- a trailing surface of the enlarged collision element, said trailing surface having a height dimension measured along the direction perpendicular to the plane of rotation and a depth dimension measured along the plane of rotation wherein the height of the trailing surface along at least half of its depth dimension is convexly negatively sloped.
