Concrete Mixing Plant Segmentation for Composition Flexibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing concrete manufacturing facilities lack flexibility and efficiency, as they are unable to quickly adjust production capacity or switch between producing different concrete compositions, leading to limited performance and inefficiencies.
Innovation Solution
A concrete manufacturing process and installation that allows for rapid adjustment of production capacity and simultaneous or successive production of different concrete compositions by using multiple storage hoppers, transporting bands, and mixing towers, with independent control of hydraulic binder, water, and adjuvants in each mixer.

Engineering Contradiction Analysis
1Adaptability or versatility
If traditional single-mixer concrete manufacturing facilities are used, then the production process is simple, but the flexibility to quickly adjust production capacity and switch between different concrete compositions is limited
Solution Approach 1:
The manufacturing facility is divided into multiple independent mixing units (mixers), each capable of operating autonomously. This segmentation allows each mixer to be independently controlled and configured for different concrete compositions, enabling rapid switching between product types without affecting other mixing operations.
Solution Approach 2:
Multiple mixers are equipped with universal feed systems that can receive various granular materials (aggregates, sands, gravels) from common storage hoppers. The feed systems are designed to serve multiple mixers simultaneously, allowing the same material supply infrastructure to support diverse concrete compositions across different mixing units.
2Productivity
If traditional batch production methods are used, then the manufacturing process is straightforward, but the ability to rapidly increase or decrease production volume in response to demand is limited
Solution Approach 1:
Multiple mixers operate in parallel and continuously, eliminating the idle time associated with single-mixer batch operations. While one mixer is being discharged, another can be receiving materials or mixing, ensuring continuous production flow. This allows rapid scaling of production volume by simply activating or deactivating specific mixing units based on demand.
Solution Approach 2:
The system allows dynamic configuration of production capacity by selectively activating or deactivating individual mixers based on real-time demand. The feed systems dynamically adjust material distribution to active mixers, and the overall production capacity can be quickly scaled up or down by controlling which mixing units are operational.
3Adaptability or versatility
If multiple storage hoppers and conveyor belts are used to feed multiple mixers, then the distribution of granular materials becomes complex, but the flexibility to produce different concrete compositions is improved
Solution Approach 1:
Multiple storage hoppers for different granular materials are merged into a unified material supply system that serves multiple mixers. The conveyor belts and feed mechanisms are integrated to distribute materials from common storage points to multiple mixing units, reducing the need for separate material handling systems for each mixer while maintaining composition flexibility.
Solution Approach 2:
Centralized storage hoppers and conveyor systems act as intermediary components between raw material sources and multiple mixers. These intermediaries buffer and regulate material flow, allowing flexible composition changes at the mixer level while maintaining a standardized material distribution infrastructure.

AI summary
A concrete manufacturing process comprising transferring granular materials into storage hoppers, pouring metered quantities of these materials from a first series of hoppers onto a first conveyor belt (6) and from a second series of hoppers onto a second conveyor belt (6'), the transport by the first conveyor belt (6) to a conveyor belt (20) being carried out simultaneously with or separately from the transport by the second conveyor belt (6') to this conveyor belt (20), and conveying by the latter said metered quantities of granular materials alternately into an aggregate tank (31) of a mixing tower (24) or into an aggregate tank (31') of another mixing tower (24).
