The s-Jet ® System (patent pending) is a new innovation in a line of consistent developments being made in the area of air jet milling. Final finenesses in the submicron range (example: d 50 0.2 µm) can now be achieved with fluidized bed jet mills, which was only possible by means of wet media milling process at the past.

Here, we report wet-jet milling exfoliation of graphite to scale-up the production of graphene as supercapacitor material. The formulation of aqueous/alcohol-based graphene inks allows metal-free, flexible MSCs to be screen-printed. These MSCs exhibit areal capacitance (Careal) values up to 1.324 mF cm-2 (5.296 mF cm-2 for a single electrode ...

Thus, it was found that wet-jet milling process led to a stable slurry because of the maintenance of not only steric repulsion but also electrostatic repulsion. Wet-jet-milled alumina slurries exhibited distinctly different stability behavior compared with ball-milled ones in terms of reflocculent efficiency and rheological properties. The ...

Wet-type jet milling (WJM) technology is relatively novel method for dispersion of nanomaterials [10]. In the WJM process, particulate material suspended in liquid medium is passed through a narrow channel at high pressure. Dispersion of material is enhanced by complex shear force from turbulent flow in the channel and cavitation from abrupt ...

A wet jet milling process was used as a novel method to prepare Al2O3 slurries. The wet jet-milled slurries showed very low viscosity compared with the ball-milled slurries. Moreover, the viscosity of the wet jet-milled slurries was constant for long times, whereas that of the ball-milled slurries increased rapidly with time. Al2O3 particles after wet jet milling …

Advantages of Wet Mill Micronization Wet-milling is a method of reducing the particle size of an API in suspension. It can readily achieve particle sizes (10-15 microns of mean volume) near to those of jet-mill micronization – without many of the disadvantages. Some of the advantages of wet-milling are:

Wet milling can be a more time-consuming process than most jet milling projects. It takes time to calculate solids percentages using material bulk density to properly set up equipment for an optimized process, and sometimes even to break down the particles. In addition, the end result of a wet milling process is — well, it's wet.
