{"title":"Jet Mills","description":"\u003cp\u003e\u003cstrong\u003eJet mills deliver sub-micron, contamination-free particle size reduction by using high-velocity gas streams instead of hammers, pins, or grinding media.\u003c\/strong\u003e Particles collide with one another inside a shaped chamber, so the energy that breaks them comes from the fluid, not from a wear surface. That makes jet milling the standard tool when a research or pilot-line workflow needs fine cathode active material, conductive carbon, solid electrolyte, or sulfide \/ hygroscopic powder ground without metal pickup or local thermal damage.\u003c\/p\u003e\n\n\u003cp\u003eThe mills listed here are spiral (pancake \/ disk-type) jet mills. Compressed air, nitrogen, or another inert gas is injected through Laval nozzles arranged tangentially around the periphery of a flat cylindrical chamber. The gas accelerates to supersonic velocity, drags the feed into a vortex, and the resulting particle-particle impacts do the grinding. Coarser particles ride the outer radius; fines exit through a central classifier that is set by the operator's choice of feed rate and gas pressure. There are no moving parts inside the grinding zone, so the process is autogenous and the only contact surfaces are the chamber walls.\u003c\/p\u003e\n\n\u003cp\u003eWhy this matters for electrochemistry work:\u003c\/p\u003e\n\n\u003cul\u003e\n\u003cli\u003eCathode active materials (NCM, NCA, LFP, LMFP, LMO, LNMO) tolerate jet milling without the lattice damage or Fe \/ Cr contamination that ball milling can introduce.\u003c\/li\u003e\n\u003cli\u003eSulfide and oxide solid electrolytes that are moisture-sensitive can be milled under dry inert gas without exposing them to milling media or atmosphere.\u003c\/li\u003e\n\u003cli\u003eConductive additives (carbon black, graphite, hard carbon) can be deagglomerated to the particle size needed for slurry rheology without breaking primary structure.\u003c\/li\u003e\n\u003cli\u003eSub-micron size distributions are produced in a single pass, with classifier-controlled top cut.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eThroughput on this page spans bench-scale (hundreds of grams per hour) to small pilot-scale (several kilograms per hour).
