Abstract: A computer controlled pumping and measuring system is used to dispense chemicals into a concrete mix. The redundant use of positive displacement pumps and flow meters ensure that any problems with the chemical dispensing are immediately caught. The computerized control system may be operable to control exact batch configurations of concrete and aggregate in conjunction with the chemical dispensing, as well as provide precise mixture control and recording of the various components.

Abstract: A system and method for mixing particulate cement with mineral aggregate(s) so as to minimize the formation and escape of dust. The system involves dispensing aggregate(s) downwardly from a hopper and simultaneously dispensing the cement particles from a tube within the aggregate hopper above the hopper opening. The cement particles adhere to moisture on the surface of the aggregate(s).

Abstract: The invention comprises a mobile concrete batch plant transportable by highway as a single unit. A cement storage hopper, a cement weigh hopper, and an aggregate weigh hopper are mounted on a standard trailer bed. The cement hopper is loaded to the desired weight from the storage bin, and the aggregate hopper is loaded as desired by a front end loader. A charging conveyor carries discharged cement and aggregate from the hoppers to a point above two oppositely facing mixing drums. The charge is dumped from the conveyor into a load hopper, and from there into a load diverter which directs it into a selected one of the two drums. Water and admixture are added and the mixing drum rotates, mixing the contents and producing concrete. The finished concrete is removed from the drum by reversing the rotation thereof, and is carried from the plant by a discharge conveyor. A second batch may be begun while the first is being mixed or discharged.
