1. Introduction
Air classifier mill is a kind of equipment used for material grinding, classifying and collection. It mainly realizes efficient grinding and particle size control through high-speed rotating grinding media and aerodynamic principle. The closed loop system in the air classifying mill plays a very important role in the operation of the air classifying mill, which is specifically manifested as follows:
2. Function of closed-loop system in ACM
2.1. Prevent dust explosion and material oxidation
The closed-loop system usually uses inert gas (such as nitrogen or carbon dioxide) as the medium, so the whole system is protected by inert gas during feeding, grinding, grading, conveying, separation and packaging. This design can effectively prevent dust explosion and material oxidation and improve the safety and stability during production.
2.2. Feedback Mechanism
A closed-loop system operates with continually monitoring the output during operation of ACM, and comparing it to the desired set point. The difference between the two values is called error signal and is used to adjust the input to the system. This feedback loop allows for real-time corrections, so it improves the stability and accuracy of the control process.
2.3. Application in automation
https://en.wikipedia.org/wiki/Programmable_logic_controllerThe closed-loop system enables automatic control during entire operation process of ACM. The automation includes equipment start and stop, status display, overload alarm and safety interlock, etc. Moreover, internal parameters, such as: temperature, oxygen content, speed of classifying wheel and feeding speed are all automatically controlled by PLC.
3. Conclusion
The closed-loop system in air classifier mill can not only prevent dust explosion and ensure safe production, but also helps to improve production efficiency and accuracy, due to automatic control.
