1 Horizontal mixing plants in the Betomix range.

2 Betomix, a concept with many advantages. 1Modular construction. The Betomix modular system permits a range of variants and arrangement options in different output capacities, all of which are derived from one basic system Well-engineered in every detail. The Betomix is defined by high quality and a long service lifetime. The entire plant is easy to operate and is extremely user-friendly. Equipment and accessories. For specific customer requirements, the extensive options available for the Betomix satisfy every need. State-of-the-art concrete production. The plant s high-quality components together afford high-performance concrete production for the most demanding quality requirements. 2

4 1 Modular construction. 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.

6 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. A Betomix plant adjoining an existing building. Betomix 3.0 on free standing steel frame.

9 2 State-of-the-art concrete 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 II, 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. The cement weighing equipment. The large-scale, robust mixing platform. 9

11 3 Well-engineered in every detail. 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. The installations beneath the weighing platform.

12 Equipment and accessories. 4Liebherr 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. Cladding of the plant. 12

14 The right mixer for every application. Liebherr has been developing and building its own mixing systems for more than 40 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. 14

15 Litronic-MPS II microprocessor control. Litronic-MPS II 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 II 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. Litronic-FMS II Installed moisture sensors Litronic-TMS 15
