Techniques or processes for efficiently producing concrete using dynamic feedback are disclosed. A concrete plant can use a control system to manage concrete production based on the dynamic feedback. The dynamic feedback can control mixing of concrete ingredients so as to yield uniform particle distribution for the concrete ingredients. The dynamic feedback can also avoid overflow situations as well as yield improved loading of the resulting concrete into a concrete transport vehicle (e.g., concrete truck).

System and method of the invention involves use of a sensor-containing body which is mounted and/or rotatably disposed along the longitudinal rotational axis of a concrete mixer drum at the close end, the sensor-containing body being connected to a conduit for introducing water, chemical admixture, gas, and/or cleansing fluid through the closed end of the drum into the mixer drum. Numerous heretofore unrealized combinations of advantages and benefits are provided within the concrete industry by the invention.

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for preparing a concrete mixture. One of the methods includes controlling an ingredient metering system to measure and add a plurality of ingredients to a concrete mixture, measuring characteristics of at least one ingredient of the ingredients using a particle analyzer, determining an estimated rheometry measurement of for the concrete mixture, obtaining an actual rheometry measurement of the concrete mixture, and selectively controlling the ingredient metering system to add one or more additional ingredients to the concrete mixture based on a comparison of the estimated rheometry measurement with the actual rheometry measurement.

A drum control system includes a mixture sensor and a controller. The mixture sensor is configured to be positioned within a drum to engage with drum contents to facilitate acquiring drum contents data indicative of a property of the drum contents. The controller is configured to control a drive system to rotate the drum at a first, unmixed speed following receipt of the drum contents by the drum where the drum contents including ingredients of a concrete mixture; acquire the drum contents data from the mixture sensor and monitor the property of the drum contents as the drum rotates; and control the drive system to rotate the drum at a second, mixed speed in response to determining that the property of the drum contents indicates that the ingredients have been sufficiently mixed.

Aspects involve an aggregate plow system that may be used in a system for cooling aggregate, such as may be found in a batch plant involved in producing concrete. The plow system generally contacts aggregate as it is conveyed by a conveyor belt to create a furrow within the aggregate prior to dispensing of liquid nitrogen or other coolant onto the aggregate. Additionally, the plow assembly may mix the ingredients of the aggregate on the belt by disputing the aggregate piled on the conveyor belt. The formation of the furrow, in place of a mound of aggregate on the belt, aids in retaining liquid nitrogen in the furrow such that it may better penetrate into the aggregate and thereby improving cooling. In either and both ways, the plow assembly improves dispersion of the coolant on and into the aggregate as it is conveyed by the conveyor belt.
