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: A system for transferring coloring agents for concrete to a ready mix truck or the like, includes a tank for receiving coloring agents. The tank includes lines for supplying it with water and a pump for transferring the coloring agents to the ready mix truck through a discharge line.

Abstract: The present invention relates to a method and an apparatus for diluting a liquid colorant. The method and apparatus are especially suitable for use in conjunction with the manufacture of colored concrete products. The method of spraying includes, providing a liquid colorant, diluting the liquid colorant with a diluting liquid, and spraying the diluted liquid colorant onto uncured concrete and/or on mold surfaces prior to filling with uncured concrete. The apparatus for spraying a diluted liquid colorant includes a flow path for a diluting liquid, a liquid colorant pump connected to the flow path, a mixer for mixing the diluting liquid with the liquid colorant, and a sprayer connected to the flow path.

Abstract: An apparatus and a method are provided for continuously pumping liquid coloring composition to a destination without interruption in flow. This allows all loads delivered to multiple mixing chambers, for concrete, cement or the like, to be uniform, such that the resultant colors of the poured materials are uniform in color when compared to each other. The apparatus also includes a system for recirculating liquid coloring composition so as to reduce its viscosity such that it is of lower viscosity and therefore, flowable for pumping to the desired destination.
