Abstract: A system and apparatus for preparing bulk quantities of dry colorant or pigment for blending with mortar are described. The system mixes the three primary pigments of black, red 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 slider valve. The slider valve is in flowing communication with a transition piece, and the transition piece is in flowing communication with a vibratory tray having an exit opening. 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.

Abstract: Systems and methods for the advanced batching of liquid colorant for dispensing into loads of wet concrete are described. A color station makes the batches of liquid colorant at the direction of a central authority. The color station includes numerous different liquid colorants that are combined to form a specific color of liquid colorant. The color station is in contact with the central authority and receives and transmits information and data to and from the central authority. Proximity detection is used to initiate the processing of the batches of liquid colorant.
