TL;DR: In this paper, a crystalline bulk powder of N-(1-((2,4-diamino-6-pteridinyl)methyl)-3, 4-dihydro-2H-1, 4benzothiazine-7-carbonyl)L-α-aminoadipic acid is treated by using an impact grinding method or a jet mill grinding method to give a finely ground powder.
Abstract: A crystalline bulk powder of N-(1-((2,4-diamino-6-pteridinyl)methyl)-3,4-dihydro-2H-1,4-benzothiazine-7-carbonyl)L-α-aminoadipic acid is treated by using an impact grinding method or a jet mill grinding method to give a finely ground powder. Solid oral preparations containing the thus obtained finely ground powder as the active ingredient can quickly release the active ingredient and high content uniformity can be ensured without adversely affecting the stability.

TL;DR: In this paper, high purity Yb3+ doped Lu2O3 powder has been synthesized by the co-precipitation method using a commercial jet mill machine.
Abstract: High purity Yb3+ doped Lu2O3 powder has been synthesized by the co-precipitation method. The powders underwent a jet milling at various feed rate using a commercial jet mill machine. It is found that jet milling is very effective in breaking up of large agglomerates without cross-contamination. Median agglomerate size decreased from 8.74 μm to 1.06 μm when jet milled at a feed rate 0.75 lb/hr. There was no noticeable increase in impurities picked up during the jet milling process in the final powder obtained after a sacrificial run that was carried out for the purpose of conditioning the surface of the liner. Homogeneous, uniform, and highly transparent ceramic was obtained from the ceramic hot pressed with the final jet milled powder compared to the one made from as-produced powder where some defects and splotches are often observed. Transmission of the Yb3+:Lu2O3 ceramics obtained from the jet milled powder is very close to the theoretical limit, demonstrating the excellent quality of the transparent ceramic.

TL;DR: In the pulverizing process, the application of centrifugal force to the particles in the region of the fluid jet or jets causes more energy to be used on the particles as discussed by the authors.
Abstract: The pulverizing process involves breaking down particles in a fluidized bed by means of a fluid jet (6, 7). The application of centrifugal force to the particles in the region of the fluid jet or jets causes more energy to be used on the particles in the fluidized bed, particularly in the vicinity of the fluid jet entrance.

TL;DR: In this paper, a two-stage system includes sieving the rolled product for further size reduction in a jet mill, which is used to process the resulting powder for further reduction.
Abstract: Doped silicon particles, including powder suitable for plasma spraying semiconductor devices, is formed by liquid doping applied to larger particles, which are then milled to a smaller size. Doped or undoped silicon may be milled by a roller mill including silicon rollers and advantageously having feed and collection systems formed of silicon and operated in a nitrogen ambient. A two-stage system includes sieving the rolled product for further size reduction in a jet mill.
