Cement plant raw meal and clinker batching control system / SM8000 fully automatic concrete batching control system

Application

The SM8000 series concrete batching plant control system, with a programmable logic controller (PLC) at its core, pioneered a working mode of "independent batching control + integrated electrical timing control management + upper-level computer network management." It enables comprehensive management of the entire concrete production process and its data, allowing for automated control.

System Advantages

1.  
2. Modular design with strong redundancy: Independent batching control for each material → Integrated batching control by the manager → Batching monitoring and management by the host computer → Seamless connection between network computer management, realizing decentralized control and centralized management.
3. The SM40-H series batching controller adopts CAN-bus industrial fieldbus communication and features a sampling rate of 200 times/second and independent opening and closing of the material gate. Compared with traditional systems, it is faster, more stable and reliable in batching, and the batching process can fully meet the process requirements of any mixing plant (building).
4. The programmable controller is based on an industrial-grade embedded microprocessor and is designed according to ultra-industrial standards. It features a wide voltage power supply of 85-265VAC, an all-metal industrial-grade structure, wide temperature range, resistance to electrical interference, and lightning protection, making it suitable for use in a variety of harsh environments.
5. It can be connected to 1 to 9 batching instruments via a communication port. The batching instruments are defined as: aggregate meter, cement meter, additive meter, water meter, extended aggregate meter, and extended powder meter. Each meter can batch four types of materials, which can fully meet the requirements of commercial concrete mixing plants.
6. Lightning protection and EMI interference suppression design measures ensure reliable lightning protection and interference suppression capabilities for this control system.

Features

1. In electrical design, interlocking functions are implemented between equipment to ensure safe production.
2. High-voltage and low-voltage circuits are separated, and leakage protection, lightning protection, and surge protection devices are installed.
3. The electrical input and output are isolated by relays, and the valve control part is protected by insurance.
4. The control modes include automatic, semi-automatic and manual.
5. Set up the machine side control button box.
6. The instrument is produced using advanced SMT technology, with high precision and good reliability.
7. The host computer uses a Windows operating system, the software is written in C language, and it uses a real-time SQL SERVER data server for easy network management.
8. The software interface is user-friendly and real-time graphic animation displays the production process.
9. Powerful alarm prompt function, all operator operation records are stored in the database.
10. Rich reports and report management functions.
11. Remote maintenance function can be realized.
