The Silo/Bin level measurement and control system solves the problem of frequent dumping accidents in the powder silo of the mixing station during the feeding process. It avoids the problems of dust flying, waste of cement, and environmental pollution. It reduces the equipment damage caused by the collapse of the dust removal hood of the mixing station Other issues and prevents the safety issues of the workers present.
The importance of Silo/Bin level monitoring
In the production process of the mixing station, the material in the powder silo is replenished in time by means of pneumatic conveying. Most of the dust collectors on the top of the powder silo of the mixing station lack normal maintenance. During the replenishment of the tank body, the pressure of the powder silo is too high, causing “roof fall”. Cement overflows from the dust collector or safety valve. Or “lift the top”, the separation of the top cover of the powder silo from the body of the powder silo occurs.
The intelligent safety system of the powder silo passes through the intelligent detection equipment installed on the silo. achieve:
- Predict the amount of storage in the warehouse and control the amount of feed;
- Three-level protection to prevent the occurrence of “top falling” and “lifting top” accidents;
- Prevent the wrong storage of cement, fly ash, and mineral powder, and prevent construction quality accidents;
- Cloud platform monitoring platform, real-time monitoring of the status parameters of the powder silo;
Silo/Bin material level measurement system
- Instead of “manual hammering”, the remaining amount of materials in the warehouse can be controlled at any time to provide a basis for procurement and inventory;
- The resistance rotary switch is intelligently controlled, and the signal is incorporated into the material level measurement system, which greatly extends its service life;
- Real-time alarm on the feeding surface when feeding, to prevent the occurrence of “roof fall” accidents;
- The application of product intelligent diagnosis algorithm solves the difficulties of heavy hammer level gauges in the industry that it is too faulty and difficult to maintain;
- The control system adopts a distributed network system, wireless transmission, stable and reliable, and fast wiring;
- Reserved information interface to meet the needs of remote control and ERP management system;
- Distributed control system layout, display the working status of the entire system and equipment parameters on the touch screen;

Important components of the system
- High-altitude material level detector
Installed on the top of each silo, it is the main measuring equipment of the material level measuring system. It can more accurately monitor the amount of storage in the warehouse in real time, and has the characteristics of resistance to heavy dust and long service life.
- High-performance anti-rotation level switch
The anti-rotation material level switch is installed vertically downward to detect whether the motor is working. Through the safety feeding valve to start and stop the rotation resistance, the service life is extended to 3-5 years; with the central control touch screen alarm and the ground terminal alarm, it can effectively prevent the occurrence of “top falling” accidents.
- Central control system
It adopts a 15-inch touch LCD screen, an embedded operating system, and is equipped with the material level measurement system software independently developed by the company. The equipment adopts 485 communication interface, which has the characteristics of fast transmission rate, high signal strength, and low failure rate.
- Ground display terminal
One set is equipped at the bottom of each silo, which is used for sound and light alarm when the material level triggers the anti-rotation switch alarm (synchronized with the weighing room alarm), real-time display of material weight and percentage, promptly reminding the operator to take measures to avoid accidents.
- Safety feeding valve
The safety feeding valve is installed at the feeding port of the powder silo, which can effectively prevent the wrong silo from loading, reduce management costs, ensure the quality of concrete, and prevent production accidents.
- Remote display
Remote monitoring shows whether the current silo can be loaded, and guides the vehicle to load the corresponding silo.

Safe feeding system for powder silo
The remote display of the weighing room shows the warehouse number and the material is allowed to be loaded. The driver holds the card to the ground display terminal and swipes the card if the warehouse allows loading. When the card number is the same as the warehouse number. Only then can the feeding valve be automatically opened.
After the card is valid, the access control baffle is automatically fully opened within 15 seconds. After swiping the card again, the access control shutter will automatically be fully closed within 15 seconds.
The powder safety feeding valve system comes with a closed door detection. Real-time detection of closed door status.
The feeding valve cannot be opened without swiping the card or reading the correct ID information
After loading, the driver needs to swipe his card to close the access control. Then go to the weighing room to hand in the card, otherwise the system prompts that the access control is open. The weighing house will not weigh the vehicle.
At present, the loading port of the cement silo of most mixing plants adopts simple mechanical locking methods. In actual production, it is easy to cause the wrong material to enter the silo, and the loading is not closed and locked. The intelligent material level system for powder silo developed by our company. It has the advantages of easy installation and maintenance, accurate measurement, high safety in use, and no need to stop production during installation. It is currently the preferred solution for real-time measurement of the powder silo level on the market.
