An air classifer mill (ACM) is a type of powder processing equipment. It is used to grind and classify material. For heat-sensitive material, the temperature and humidity should be controlled during operation. This passage would explore how to control the temperature and humidity of heat-sensitive material.
How to Control Temperature
1. Airflow adjusting
By regulating airflow entering the chamber can heat or cool the material during processing. For heat-sensitive material, to introduce cold air can prevent overheating, while heated air can be used for drying high-humidity material.
2. Closed-loop system
Воздушный классификатор мельница can operate in closed-loop system where conditioned air is recycled. This system can not only save energy but also better control temperature and humidity by continuously circulating the air used during grinding.
Inert gas, like nitrogen, can replace airflow in this system. Inert gas can better handle material with explosion risk or highly sensitiveness, to ensure safety.
3. Real-time monitoring
Equip air classifier mill with sensors to monitor inlet and outlet temperature. The sensors can help to make real-time adjustment to ensure heat-sensitive material not to degrade during grinding.
How to Control Humidity
1. Pre-drying treatment
Before material entering air classifier mill, using drying equipment such as dryer to dry the material to reduce humidity.
2. Airflow adjusting
By adjusting airflow can not only control the temperature, but also reduce the humidity of the material being processed. This method is particularly useful for hygroscopic material which is easy to absorb moisture from the environment. By regulating airflow to control humidity can avoid agglomeration of material and ensure liquidity and diversification of material when passing through grinding chamber.
3. Other operating conditions
★ Reduce rotation speed: properly reducing the rotation speed of air classifier mill can reduce the adhesion of material in grinding chamber.
★ Control the feeding amount: by controlling feeding amount can avoid accumulation caused by excessive feeding, which can somewhat reduce the humidity of material.
Заключение
Air classifier mill plays a vital role in handling heat-sensitive materials by effectively controlling temperature and humidity throughout grinding process. It can prevent material from deterioration and ensure product quality. At the same time, air classifier mill has become important equipment in industrial production due to its properties of high efficiency, high stability and environmental protection. In recent years, the market of air classifier mill has maintained a steady growth trend.
