Liebherr-Mischtechnik GmbH
About
Liebherr-Mischtechnik GmbH, part of the Liebherr Group's concrete technology division, develops and manufactures complete concrete production and handling systems from its headquarters in Bad Schussenried, Germany, with additional production facilities in Guarantingueta (Brazil), Rayong (Thailand), and Plovdiv (Bulgaria). The company provides mixing plants, truck mixers, conveyor belts, concrete pumps, recycling plants, and control systems as an integrated concrete technology offering. Their recycling systems process returned concrete and wash water from truck mixer and plant cleaning operations, separating aggregates and fines for reuse. The LRS screw recycling system (models LRS 606, LRS 708, LRS 806, LRS 908) uses a screw mechanism with compact footprint and high discharge height, processing 12-22 cubic meters per hour. The LRT trough system provides larger wash water capacity for high-throughput operations. A galvanised dosing buffer accepts residual concrete from up to six truck mixers simultaneously for even material transfer to the recycling plant during peak periods. The control systems division integrates process automation, recipe management, and quality assurance for batching operations. While primarily a concrete technology provider, the recycling and wash water treatment capabilities offer peripheral relevance to water management through concrete wash water processing and solids recovery for compliant discharge.
Key Products
Stationary and mobile concrete batching plants that blend aggregates, cement, water, and additives in precise proportions for ready-mix and precast concrete production.
Rotating drum truck-mounted mixers that transport and agitate concrete from the plant to the job site, maintaining workability during transit.
Material handling systems integrated with truck mixers for efficient aggregate and concrete transport on construction sites.
High-pressure pumps that deliver freshly mixed concrete through pipelines to placement points, including boom pumps for vertical and horizontal reach.
Systems that process returned concrete and truck mixer wash water, recovering aggregates and fines while treating wash water for reuse or compliant discharge.
Automated batching control and measurement technology for mixing plants, managing recipe execution, weighing accuracy, and production documentation.
Weighing, dosing, and moisture measurement instrumentation integrated into mixing plants for quality control and recipe compliance.
