Abstract
A system and apparatus for preparing bulk quantities of dry colorant or pigment for blending with mortar are described. The system mixes pigments of black, red, white and yellow to prepare a batch of the dry colorant having a particular color. The pigments or dry colorant are generally a powder of metal oxide crystals. The system includes pigment dispensers, wherein each pigment dispenser includes a tote that is in flowing communication with a valve. A receptacle receives pigments from the exit opening of the vibratory trays. A control unit serially operates the vibratory trays to dispense the pigment from each tote. A scale measures the weight of the pigments in the receptacle. The scale is in operational communication with the control unit.
