Site selection principles
Convenient transportation: close to the raw material supply area and construction area to reduce transportation costs.
Geological conditions: give priority to geologically hard areas to avoid soft foundations affecting equipment stability.
Environmental requirements: far away from residential areas, in line with noise and dust emission standards.
Site layout
Functional zoning: clearly divide the mixing host area, aggregate yard, laboratory, office area and sewage treatment area.
Hardening treatment: The site must be hardened with C20 and above concrete, with a thickness of ≥20cm, and a drainage system must be set up.
Aggregate yard: sand and gravel are stored in separate warehouses, the height of the rain shelter must meet the requirements of mechanical operation, and the height of the partition wall is 3 meters to prevent cross-material.
Core equipment
Mixing host: forced twin-shaft mixer (such as HZS180) is recommended, with high efficiency and uniform mixing, suitable for conventional and high-performance concrete.
Weighing system: electronic scales are set for aggregates, powders, and liquids, with an accuracy of ±2% and ±1% respectively.
Conveying system: Aggregates are conveyed by belts, and powders are conveyed by screw conveyors or pneumatic chutes.
Auxiliary facilities
Storage system: Bulk cement tanks (single tank over 100t), special tanks for admixtures.
Control system: PLC automation control + IoT monitoring, supporting remote fault diagnosis.
Backup power supply: Equipped with diesel generator sets (such as 200kW) to ensure continuous production.
Standardized process
Batching: Real-time detection of aggregate moisture content, increase the detection frequency on rainy days.
Mixing: Forced mixing time is 30-60 seconds to ensure no segregation or water seepage.
Transportation: Use a mixer truck with a capacity of more than 6m³, and stir at a low speed on the way to prevent segregation.
Quality assurance
Laboratory configuration: Standard curing room (spray curing), mechanics room, etc., equipped with constant temperature equipment are required.
Data monitoring: Production data is uploaded to the regulatory department in real time to ensure accurate mix ratio.
Dust control
Closed silo + fog cannon spray system.
Powder tank dust removal: equipped with pulse dust collector to reduce cement dust.
Wastewater treatment
Multi-stage sedimentation tank: Separate sand and gravel slurry for recycling.
Noise management
Low-noise equipment: such as air conveying chute instead of screw conveyor.
Safety facilities
Lightning protection system: Cover the entire station, and the grounding grid is reliably connected.
Protective device: Protective cover is installed on the transmission parts, and warning signs are set in dangerous areas.
Operation and maintenance strategy
Regular maintenance: Check the wear of the main mixing machine blades every quarter.
Intelligent early warning: Predict equipment failure through the Internet of Things system.
Cost optimization
Automated production: Reduce manual errors and reduce energy consumption by 20%-30%.
Resource circulation: Crushing and recycling of construction waste.
Technology upgrade direction
Green energy: electric mixer trucks, hydrogen power.
AI integration: such as AI visual monitoring of concrete fluidity.
