Automation transformation can improve the comprehensive production efficiency of concrete mixing plant production lines by 20% -40%. The core is achieved by compressing manual errors, optimizing process connections, and ensuring batching accuracy.
1, Quantitative data on efficiency improvement (I) measured values on the front line (domestic mixing plant renovation cases from 2022 to 2024)
Small scale station (annual output of 100000 cubic meters): The manual single shift production capacity is 60-80m ³, and after renovation, it is 90-110m ³, with an increase of 25% -38%.
Large scale stations (with an annual output of over 300000 cubic meters): The manual single shift production capacity is 150-180m ³, and after renovation, it is 200-250m ³, with an increase of 22% -35%. (2) Optimization of the proportion of faults and delays
The proportion of downtime caused by ingredient errors and delayed feeding during manual operation is 15% -20%, which has been reduced to 2% -5% after the renovation. 2, The key contribution of efficiency improvement (1) is the optimization of the accuracy of the batching system
Adopting weight loss automatic measurement, the batching error is reduced from manual ± 2% to within ± 0.5%, avoiding rework or stagnation, and shortening the batching time for a single plate (1m ³ of material) by 10-15 seconds. (2) Process connection compression
Automatically triggering the entire process of feeding, mixing, and discharging, eliminating the waiting time for manual material calling and manual machine start-up, and reducing the entire production cycle from 90-120 seconds to 75-95 seconds. (3) Efficiency improvement in material/warehouse replacement
The preset ratio parameters have reduced the time required for equipment cleaning and parameter adjustment during material replacement from 15-20 minutes manually to 5-8 minutes. 3, Boundary Limitations for Efficiency Improvement (Part 1) Adaptation Scenarios
Only for standard mixing plants with a capacity of ≥ 1m ³, the cost-effectiveness of renovating small-scale test stations (≤ 0.5m ³) is low, with an efficiency improvement of less than 10%. (2) Maintenance requirements
Full time automated operation and maintenance personnel are required. If there is a lack of operation and maintenance, the loss of system failure and downtime will offset 30% -50% of efficiency gains.
