Particle collisions, also known as particle-to-particle collisions, are the core mechanism behind jet milling. In this process, materials are accelerated by high-velocity compressed gas and collide with one another at extremely high speeds within a grinding chamber.
Unlike traditional milling methods that use mechanical media such as beads, blades, or disks, jet mills rely entirely on the kinetic energy of these collisions. This eliminates the risk of contamination from grinding tools and allows for a cleaner, more controlled milling environment.
The result is a highly efficient and uniform size reduction process, ideal for producing fine, high-purity powders. This technique is especially important in industries like pharmaceuticals, electronics, and ceramics, where material integrity is critical.
