Central Mix Concrete Plant

A: Based on AGICO factory test data and third-party inspections, the 28-day compressive strength standard deviation of concrete produced by the AGICO wet-batch plant is controlled within ±1.5 MPa. Dry-batch plants typically show a deviation above ±3.0 MPa. This is because the AGICO twin-shaft mixer completes more than 300 material folding actions within 60 seconds. A truck mixer drum only achieves about 80 mixing actions. In addition, the AGICO central metering system controls the water-cement ratio error within ±1%. This is much lower than the ±5% to ±8% error found in dry-batch plants, which rely on driver experience.

A: The AGICO Central Mix Concrete Plant uses high-chromium cast iron (Cr26) liners and blades. Their hardness reaches HRC 58-62. When processing standard C30 concrete, they can produce 80,000 to 100,000 m³ before replacement is needed. The AGICO mixer is designed with an access door and a quick-locking mechanism. Two workers can complete a full set of blade replacements within 4 hours. For high-wear applications, such as RCC or concrete with quartz aggregate, AGICO offers bimetallic composite wear plates as an option. These plates provide twice the service life.

A: Yes. The AGICO Central Mix Concrete Plant can be equipped with an optional hot water boiler (up to 60°C) or a chiller unit. Water temperature is automatically adjusted by a temperature sensor inside the water scale. In -15°C environments, AGICO also provides screw conveyors with thermal oil heating and silo insulation layers. These features prevent cement from caking. The control system includes a low-temperature start-up logic. When the oil temperature drops below 5°C, the system delays start-up and preheats automatically. This prevents damage to hydraulic components.

A: For AGICO HZS series stationary plants, it typically takes 10 to 15 working days from foundation completion to first discharge. This includes installation, wiring, and commissioning. For the mobile HZS25/35/50 models, the plant can be put into operation within 6 hours on site. AGICO provides 24-hour phone and video support worldwide. Core components, including motors, gearboxes, and sensors, are covered by an 18-month warranty. When on-site service is required, AGICO commits to dispatching an engineer within 72 hours (force majeure excluded). AGICO also maintains overseas warehouses for common spare parts.
