A containerized concrete batch plant is disclosed, comprising a container configured to contain a concrete batch plant to permit the transportation of the concrete batch plant. The concrete batch plant comprising one or more aggregate storage silos to receive a plurality of concrete elements. The one or more aggregate storage silos pour the concrete elements onto a conveyor based on quantity determination by a computer via a deductive scale. The conveyor transfers the concrete elements to a two-shaft mixer. An auger-fed hopper has an auger that is directly exposed to the contents inside the two-shaft mixer and transfers the contents inside the two-shaft mixer into the auger-fed hopper. A concrete pump has access to the auger-fed hopper and pumps the concrete inside the auger-fed hopper into a concrete output hose with a concrete output opening. A knuckle crane and/or hydraulic arms holds supersacks above the aggregate storage silos and the two-shaft mixer.

A containerized concrete batch plant is provided. The concrete batch plant includes a container configured to contain a concrete batch plant to permit transportation of the concrete batch plant. The container includes opposed ends and structural support members extending along each edge of the container to a top of the container to support a plurality of panels to enclose the container. The batch plant further includes one or more storage silos to receive a plurality of concrete elements. In addition, the batch plant includes a mixer to receive the plurality of concrete elements. The mixer mixes the plurality of concrete elements to provide concrete. The batch plant also includes a hopper to receive the concrete from the mixer. Furthermore, the batch plant includes a concrete pump to pump the concrete out of the hopper.

A mixer (1) comprises a drum (2) having at least one inlet (6) and one outlet (7). The mixer (1) furthermore comprises a drive (3) and a stirring shaft (4), which is arranged in the drum (2) and is coupled to the drive (3). Furthermore, the mixer (1) comprises a conveying device (5), which is arranged in the drum (2) and which is arranged on one and the same axis as the stirring shaft (4).
