Description

Technical Field

[0001] The utility model relates to the technical field of air flow mills, in particular to an anti-agglomeration air flow mill. Background Art

[0002] Airflow mill is a processing equipment that uses airflow to crush solid materials. In the airflow mill, solid materials are fed into the grinding machine and then crushed by the high-speed rotating grinding disc and airflow. The airflow mill has the following advantages: First, the airflow mill can grind the material finely because the collision force between the particles is small and will not cause excessive crushing. Secondly, the airflow mill has an adjustable grinding particle size and can change the degree of crushing as needed. In addition, the airflow mill can also eliminate impurities and provide pure fine powder. Finally, the airflow mill is safer and more reliable for the treatment of flammable, explosive and harmful materials because the airflow mill does not require the use of mechanical force for grinding, reducing potential safety risks. However, the traditional airflow mill generates a strong airflow to bring the material into the abrasive for grinding, and then passes through a classifier to separate the coarse particles and fine particles. However, when the traditional airflow mill grinds magnetic powder raw materials, the magnetic powder particles have a certain magnetism, and may be squeezed and agglomerated during the grinding process, thereby affecting the normal processing of the magnetic powder.
