Abstract: An apparatus is disclosed for comminuting a colored pigment bar and mixing the comminuted pigment with an uncolored plastic material to form a colored plastic material which is subsequently molded or extruded into a colored plastic article. The apparatus features a rotating, discontinuous cutting blade to minimize static electricity formation so as to allow more thorough mixing of the pigment with the uncolored material. A storage mechanism is also disclosed to store the colored pigment bars and bring them into contact with the cutting blade.

Abstract: A micrometer mixer having a rotary cutter with a replaceable shaver means is used to powderize pigment bars and mix it with plastic pieces.
