1、 Introduction to AF series nitrogen protected airflow crushing and grading:
Nitrogen protected airflow crushing or grading is mainly aimed at crushing or grading flammable, explosive or gas sensitive materials. By adopting nitrogen circulation and utilizing automation control and trace nitrogen replenishment technology, the overall system maintains a certain nitrogen content, constant pressure and temperature, ensuring that the materials not only meet certain particle size requirements but also meet safety, explosion prevention, and oxygen isolation temperature requirements.
