Abstract
A pigment and concrete mixer includes a pigment tank fluidly connected to a mixing auger by a hose. A pump is configured to pump pigment from the pigment tank to the mixing auger. A motor is operable to control the pump and adjust a flow rate of the pigment within the hose. The present invention adds color pigment to concrete in controlled flow for consistent color throughout concrete mix. The flow is adjusted to different rates for different color variation.
