Description

Technical Field

[0001] This utility model relates to the field of powder production equipment technology, and more specifically, to a modifier feeding spray device for an air jet mill. Background Technology

[0002] An air jet mill, also known as an air jet pulverizer or air jet mill, is a device that uses high-speed airflow to pulverize materials by causing them to collide, impact, and shear against impacting components.

[0003] Modifiers are primarily used in air jet mills to modify the surface of pulverized powder materials. After being pulverized by an air jet mill, the specific surface area of ​​the particles increases, resulting in higher surface energy and an unstable state. Modifiers can adsorb onto the particle surface, altering its surface properties; simultaneously, they can reduce particle agglomeration. During pulverization, agglomeration easily occurs due to van der Waals forces and other interactions between particles. Modifier molecules can form a protective film on the particle surface, preventing mutual attraction between particles. For example, in the preparation of ultrafine talc powder, adding a suitable modifier can maintain good dispersibility of the ultrafine particles, improving their performance in applications such as coatings and engineering plastics.

[0004] In existing technologies, when adding modifiers to air jet mills, the modifiers are mainly added by dripping them into the mill. However, this method still has shortcomings. The material does not come into complete contact with the modifier during the crushing process, which affects the surface modification effect of the powder.
