An Ammann CBT 130 TB Elba concrete-mixing plant

Ammann’s new CBT 105 to CBT 150 TB Elba concrete mixing plant are said to be linear transport-optimised and capable of an hourly output of up to 128m³.

Fast installation times, easy relocation and strict adherence to favourable transport dimensions to realise low transport costs were the goals of the Ammann development engineers. The result is a concrete mixing plant equipped with sophisticated folding mechanisms and suitable components.

The basic unit can be transported with two 40’ open-top containers and one 40’ flat-rack container. With this, the development goal of a transport-optimised plant is 100% realised. Depending on the size of the plant, the compact CBT TB Elba mixing plant is equipped with Ammann twin-shaft mixers of the CEM TP Elba series with a compacted concrete output from 2 m³ to 3.5 m³.

The newly developed linear bin series CEL 25 Elba has the storage capability of three to eight different grain fractions and an active storage capacity of 75m³ to 100 m³. It allows a wide range of applications, particularly when considering the container transport dimensions.

Depending on requirements and customer preferences, the CBT TB Elba mixing plant can also be optionally equipped with the linear bin of the CEL 35 Elba series from the Ammann portfolio with a storage capacity up to 210m³.

The individual scales for cement, water and aggregates and the optional additive scale are electrically and pneumatically installed ready for operation. Up to six cement screws can be connected to the cement scale. The aggregates are dosed and weighed on the installed weighing belt and then transferred to the inclined conveying belt. The performance of the inclined conveyor belt is designed to reach short cycle times and therefore a high concrete output of the mixing plant can be achieved. All installed plant components are connected as much as possible and pre-installed both electrically and pneumatically. During assembly, the concrete mixing plant will be unfolded, erected and the already pre-assembled weighing unit will be mounted on top.

The erection of the CBT TB Elba concrete mixing plant is said to require only a simple concrete floor slab. Foundation work is completely eliminated. For the cement silo assembly, optionally foundationless solutions up to 100-tonne silo-size are available.

Good accessibility for maintenance and cleaning work was also considered in the development of the CBT TB Elba and reflects the customers’ previous positive experience with Ammann concrete mixing plant.
