Technology for Production of Monodisperse Spherical Granules

The conducted study shows the possibility of improving the technology for producing monodisperse spherical granules. By modifying the surface of a die, it becomes possible to utilize the technology when granulating ErNi alloy. A potential for using the regime of forced capillary jet breakup with satellite droplets to expand the size-based operating range of the granulators in the finely-dispersed region has been demonstrated. To improve the granular quality, the forced capillary breakup regime with an excitation wavelength of about λ = 4.5 d should be used.
