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.

Claims

1. A system for producing batches of a dry pigment of metal oxide crystals, comprising:

a plurality of pigment dispensers, wherein each pigment dispenser comprises a tote, the tote comprises a first wall at an angle of approximately 20 degrees to approximately 40 degrees to a vertical axis and a second wall at an angle of approximately 1 degree to approximately 8 degrees to the vertical axis, a first vibrator positioned on at least one of the first wall or the second wall, the tote in flowing communication with a slider valve, the slider valve in flowing communication with a transition piece, a second vibrator positioned on a wall of the transition piece, and the transition piece in flowing communication with a vibratory tray having an exit opening;

a receptacle to receive pigments from the exit openings of the vibratory trays, wherein the receptacle is movably positioned underneath the exit openings of the vibratory trays, and wherein the receptacle slides or withdraws from underneath the exit openings;

a control unit to serially operate the vibratory trays to dispense the pigment from each tote; and

a scale to measure the weight of the pigments in the receptacle, the scale in operational communication with the control unit.

2. The system according to claim 1, where a first pigment dispenser contains black pigment, a second pigment dispenser contains yellow pigment, and a third pigment dispenser contains red pigment.

3. The system according to claim 1, wherein the vibratory trays are operated in a variable manner with the vibration of the vibrating trays reduced as the amount of pigment in the receptacle approaches a target amount.

4. The system according to claim 1, wherein the control unit comprises one or more formulas for a specific color of a mortar colorant.

5. The system according to claim 4, wherein the formulas comprise a specific amount of at least two of black, red, and yellow pigments.

6. The system according to claim 4, wherein the formulas comprise a specific amount of black pigment by weight, a specific amount of red pigment by weight, and a specific amount of yellow pigment by weight.

7. The system according to claim 1, wherein three pigments dispensers include three vibratory trays with the exit openings of the three vibratory trays positioned over an opening of the receptacle.

8. The system according to claim 7, wherein each of the three pigments dispensers are mounted to frames, and the three vibratory trays extend beyond the frames to position the exit openings over the opening of the receptacle.

9. The system according to claim 1, wherein the dry pigments consist of metal oxide crystals.

10. The system according to claim 1, wherein the dry pigments consist of non-granulated, iron oxide crystals.
