Horizontal mixing
plants in the
Betomix range

Betomix, a concept with
many advantages.

Modular construction

The Betomix modular system permits a ran­ge of variants and arrangement options in
different output capacities, all of which are

The Betomix is defined by high quality and a long
service lifetime. The entire plant is easy to operate
and is extremely user-friendly.

The mixing plants in the Betomix range are based on a sophisticated modular system. The basic module
and various adaptation modules can be combined to provide a multitude of variants and outputs. Ring pan
mixers or double-shaft mixers in various sizes can be integrated into the system for complete flexibility.

The aggregate and sand is stored in either an inline silo, star-pattern silo or circular silo. For loading the
mixer, there is a choice of a loading elevator or a loading conveyor.

Tailor-made solutions

A state-of-the-art plant using a modular system meets eve­ry requirement profile to provide the optimal solution for the
operator. Betomix plants are also exceptionally well-suited to
particularly complex plant systems. For large-scale projects,
for instance the construction of embankment dams, Liebherr
can plan and realise entire systems with temporary storage
chambers and cooling units. The parallel operation of several
Betomix plants offers hourly outputs of more than 500 cu. m
of set concrete.

The many options mean that Betomix plants can be integra­ted with existing buildings and site restrictions. As a result,
the Betomix is also very popular in the concrete product and
prefabricated unit industries.

production

High dosing accuracy when the materials are being weighed together with
moisture measurement during the ongoing process guarantee concrete of the
highest quality. Litronic-MPS, state-of-the-art real-time control, ensures the ex­act interaction of all components. As a result, the mixing plant yields maximum
output volumes and operates very economically. The quality of the components
and the long service lifetime of all moving parts guarantee operation with virtually
no downtime over a period of many years. The entire plant concept is extremely
user- and maintenance-friendly.

Betomix plants owe their dependability to careful planning down to the very last detail. They have been de­veloped with the support of more than 50 years of practical experience. All areas of the plant are extremely
easy to access. All cables, pipes and other elements are protected in mountings and ducts in order to prevent
malfunctions. Provision has also been made for the retrofitting of additional equipment. For example, weighing
equipment for silica or ice can be integrated into the plant at a later date. The steel construction is extensively
galvanised to ensure that the plant is resistant to corrosion and weathering.

Liebherr provides a wealth of options and additional equipment to satisfy all customer requi­rements and demands. Depending on the geographical location of the plant, the Betomix
is available with an insulated cladding and heating for operation during the winter. For hot
regions, the Liebherr range includes all components for adding ice. Practical options, for
example high-pressure mixer cleaning, make day-to-day operation of the plant significantly
more straightforward. Depending on the mixer type, the Betomix is also available with
twin loading bays.

The right mixer for every application

Liebherr has been developing and building its own mixing systems for more than 50 years. Tests using the widest pos­sible range of materials are carried out in the company’s mixing technology laboratory, where the systems are subject to
ongoing development and optimisation.

Based on the well-proven Type R ring-pan mixer, there are further versions with additional agitator tools for higher-quality
grades of concrete. Depending on the size, the Type RIM is available with one or two mechanical agitators (RIM-M /
RIM-D). The Type RIH has one or two hydraulically-driven agitators, with the advantage that the speed of agitator rotation
can be continuously varied (RIH-M / RIH-D). Ring-pan mixers are available with capacities from 0.5 to 3.0 cu.m.

Liebherr’s double-shaft mixers are extremely strong and are suitable for high output rates. The Type DW is available with
nominal volumes of between 2.25 and 6.0 cu. m. All mixer systems from Liebherr are particularly maintenance-friendly.

Litronic-MPS microprocessor control

Litronic-MPS is based on an open system concept derived to a large extent from industrial standards, enabling the
latest hardware and software developments to be incorporated without difficulty. Screen displays allow all work se­quences to be followed easily, and the necessary interfaces for connection to existing data processing systems are
provided. Extensive additional software packages are available and can be installed retrospectively.

Litronic-FMS moisture measurement

To ensure that aggregate moisture is measured accurately during the dosing operation, we use an intelligent Liebherr
capacitive-type sensor.

Litronic-TMS temperature measurement

Liebherr offers Litronic-TMS for non-contact temperature measurement of the material in the intensive mixer.
