ABSTRACT:
A blender for plastic materials weighs a charge of virgin plastic pellets as they are added to a hopper, similarly weighs plastics regrind material as it is added to the hopper, calculates the weight of color material (or other additive) on the basis of the actual virgin material weight and the desired color percentage, calculates from the weight of color material and a calibration of a volumetric feeder the volumetric amount of color material needed and then dispenses the calculated volume of color material. The apparatus is hybrid, using weight ratio measuring devices for the primary components and a volumetric feeder for dispensing the additives.
