Precast Concrete Batching Plant
HZN-Z Series
Compact concrete batch plant configured with planetary concrete mixer and skip hoist feeding for small-to-medium precast factories with limited spaces
- Production Capacity 35–75 m³/h
- Plant Configuration Compact structure with planetary mixer for high uniformity
The combined concrete batching plant integrates a JN-AH skip-hoist vertical shaft planetary mixer with HP series aggregate batching machines, offering both cumulative and individual weighing options. The plant can be configured with dedicated weighing modules for cement, mineral additives, water, and chemical admixtures, alongside a complete air supply system. With a centralized control system, the entire mixing process is completed automatically, with manual switching available to support both automatic and semi-automatic production modes.
This batching plant features a compact structure, small footprint, and stable, reliable performance. It is suitable for mixing dry, semi-dry, high-performance, and high-strength concrete. The mixer can be configured with two discharge gates according to production line requirements, allowing one mixer to supply multiple production lines. It is widely used in block production, pipe pile manufacturing, PC component production, and special high-performance concrete mixing applications.

Process Flow
Main Components
Concrete Mixer
JN-AH series concrete mixer is a vertical shaft planetary mixer equipped with skip hoist, featuring an electric winch for material loading. Its compact structure ensures a small footprint and easy installation, while the planetary mixing action delivers superior homogeneity. To meet diverse production line needs, the concrete mixer can be configured with two discharge gates, allowing a single mixer to serve multiple production lines simultaneously.
Aggregate Batching Machine
HP series aggregate batching machines adopt sectional assembled bin panels for easy installation. Pneumatic batching ensures fast and accurate dosing, while belt discharge enables clean and rapid unloading. Both cumulative and individual weighing types are available to meet different batching requirements. Suitable for concrete construction sites, commercial concrete batching plants, and precast concrete factories.
Screw Conveyor
The cement screw conveyor features a housing made of high-quality steel pipes. Each section is connected by flanges. The conveying screw adopts a variable-pitch blade design, allowing smooth and stable powder material conveying.
Weighing System
The weighing system is equipped with high-precision load cells to ensure consistent and accurate measurement.
For material release, it utilizes pneumatically operated butterfly valves of premium quality, providing rapid actuation and a hermetic seal to prevent leakage.
