Nano-micronization device
Newly developed micro-particle technology (droplet collision method)
The "G-smasher," a disintegration device using the droplet collision method, employs a Laval nozzle to generate a supersonic air jet and supplies a slurry into the nozzle. The slurry supplied into the nozzle is atomized and accelerated by the adiabatic expansion of compressed air, colliding at high speed with a collision plate. Traditionally, jet mills utilizing Laval nozzles have been widely used for dry grinding, but the particle ejection speed was limited to subsonic (100-200 m/s). In this method, by suppressing the generation of shock waves at the slurry supply section within the nozzle and exploring a stable supply method for the slurry, it became possible to atomize the slurry within the nozzle and accelerate it up to supersonic speeds (360 m/s). Furthermore, since this method supplies the slurry to the air jet for grinding without media, it can reduce contamination caused by wear of seals and media. Additionally, the droplets supplied inside the nozzle are accelerated and simultaneously cooled by the adiabatic expansion of air, which helps to suppress the heat generated during grinding, eliminating the need for a cooling unit.
