Transit Mix Concrete Plant

A transit mix concrete plant, also known as a dry-mix concrete batching plant, has the core function of precisely metering aggregates, cementitious materials, and admixtures according to the mix proportions, directly loading them into concrete mixer trucks. The mixing process is completed en route by the trucks. Haomei Machinery's transit mix concrete batching plants focus on three core aspects: dry batching accuracy, loading efficiency, and landing cost, providing a cost-effective dry material production solution for long-distance commercial concrete delivery and decentralized infrastructure projects.

The core performance of a transit mix plant lies in the accuracy of dry material metering, which directly determines the stability of the finished concrete quality after transportation and mixing. Haomei dry-mix concrete plants adopt a fully independent weighing and metering architecture. The aggregate unit is equipped with a multi-compartment batching machine, supporting simultaneous metering of 3-5 types of aggregates, with a stable dynamic weighing error of ≤±2%. Cement, fly ash, and other powdery materials are conveyed by screw conveyors paired with precision electronic scales, achieving a metering error of ≤±1%. Dry powder admixtures utilize micro-weighing modules, with metering accuracy controlled within ±1%. The system incorporates a dynamic drop compensation algorithm, automatically adjusting valve closing timing based on material particle size and bulk density to reduce replenishment time. Overall metering accuracy fully complies with EN 206 and ISO 19720 international standards, with minimal batch-to-batch fluctuations in dry material ratios. Combined with standardized water-addition and mixing processes in mixer trucks, it can stably output concrete of all grades from C10 to C50.

The transit mix plant equipment is standardly equipped with a trough-type inclined belt continuous conveyor system. Mainstream 60m³/h and 90m³/h models are matched with 650mm and 800mm wide belts respectively, corresponding to rated conveying efficiencies of 90t/h and 120t/h. Aggregate supply rhythm is perfectly matched with the metering cycle, eliminating interruptions. The unloading unit adopts a liftable dry material unloading hopper, adaptable to the feed inlets of mixer trucks of different heights. The unloading time for a single batch of material is controlled within 10 seconds, and the complete loading time for a single truck is ≤8 minutes. A single dry mix concrete plant can complete the batching and loading of 7-9 mixer trucks per hour. The entire system supports continuous batching and sequential loading scheduling, fully adapting to the concentrated delivery needs of commercial concrete plants during peak hours, reducing vehicle queuing time and improving the overall operational efficiency of the plant.

Compared to wet mix concrete plants of the same capacity, dry mix concrete plants eliminate the mixing host, water supply system, and host cleaning unit, significantly simplifying the overall structure and reducing initial procurement costs by 30%-35%, while also reducing civil engineering investment. The entire station adopts a modular design, with over 80% of core components pre-assembled in the factory. After disassembly, all components can be adapted for standard container transportation, making cross-border logistics costs controllable. On-site installation only requires module flange connection and wiring, eliminating the need for large-scale secondary welding. Installation, commissioning, and production can be completed in 5-7 days, shortening the construction period by nearly 40% compared to traditional wet mixing plants. The overall layout is compact and efficient, requiring approximately 20% less floor space than wet mixing plants for the same production capacity. It can be directly connected to existing raw material storage yards or commercial concrete plants, offering excellent site adaptability. An optional pulse bag filter system is available, with dust emission concentrations ≤30mg/m³, meeting environmental compliance requirements in various regions.

The transit mix concrete batching plant is equipped with an industrial-grade PLC control system and a color touchscreen human-machine interface, supporting multi-language switching. It features automatic batching, automatic unloading, and production data storage and traceability. It can display real-time material weighing data and equipment operating status, automatically issuing warnings and indicating fault locations in case of abnormalities. The equipment operation logic is clear and intuitive; ordinary operators can operate independently after 3-5 days of training. Targeting the export market, the equipment supports customized 380V/415V multi-voltage systems, comes standard with CE certification, and can quickly adapt to the power grids and regulatory standards of different countries. Core wear parts adopt internationally recognized specifications, with extensive procurement channels, ensuring controllable long-term operation and maintenance costs.

Based on years of experience exporting equipment, transit mix plants are highly suitable for market scenarios with large delivery radii and dispersed construction sites, achieving standardized commercial concrete supply with lower investment. Haomei Machinery's dry-mix concrete stations, with their continuous optimization of metering accuracy and loading efficiency, perfectly match the dual demands of commercial concrete operators for quality and efficiency. This makes them a cost-effective choice for regional commercial concrete network development and large-scale, long-term infrastructure projects.
