A high-tech materials manufacturer required ultrafine alumina (Al\u2082O\u2083) powder for advanced ceramic and electronic applications. The key requirements included very fine particle size, narrow distribution, high purity, and minimal contamination. Due to the hardness and brittleness of alumina, conventional mechanical grinding methods could not meet the customer\u2019s quality expectations. Epic Powder was selected to provide a jet mill grinding solution to produc alumina for the client.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Als Rohmaterial diente hochreines Aluminiumoxid (Al\u2082O\u2083) mit einer Mohs-H\u00e4rte \u00fcber 9. Der Kunde legte Wert auf eine kontaminationsfreie Verarbeitung und eine enge Partikelgr\u00f6\u00dfenverteilung, um eine gleichbleibende Leistung in den Folgeprozessen zu gew\u00e4hrleisten. Nach einer technischen Bewertung w\u00e4hlte Epic Powder ein Flie\u00dfbettstrahlm\u00fchle<\/strong>, was sich besonders eignet f\u00fcr ultrafeines Pulvermahlen<\/strong> aus harten Materialien.<\/p>\n\n\n\n

Im Produktionsprozess wird die Druckluft vor dem Eintritt in die Strahlm\u00fchle gefiltert und getrocknet. Das Aluminiumoxidpulver gelangt in die Mahlkammer, wo ein Hochgeschwindigkeitsluftstrom die Partikel beschleunigt. Dieser Luftstrom bewirkt intensive Partikelkollisionen und reduziert so die Partikelgr\u00f6\u00dfe, anstatt auf mechanische Einwirkung zu setzen. Ein interner dynamischer Klassierer steuert pr\u00e4zise die Endfeinheit und l\u00e4sst qualifizierte ultrafeine Partikel aus dem System austreten, w\u00e4hrend zu gro\u00dfe Partikel automatisch zur weiteren Vermahlung zur\u00fcckgef\u00fchrt werden. Das vollst\u00e4ndig geschlossene System gew\u00e4hrleistet einen sauberen, stabilen und zuverl\u00e4ssigen Betrieb.<\/p>\n\n\n\n

Nach Inbetriebnahme und Parameteroptimierung erzielte die Strahlm\u00fchle stabile Produktionsergebnisse. Das Endprodukt erreichte eine Partikelgr\u00f6\u00dfe von D97 = 2,07 \u03bcm<\/strong>, mit einer gleichbleibenden Leistung von 130 kg\/h<\/strong>. Das ultrafeine Aluminiumoxidpulver wies eine enge Partikelgr\u00f6\u00dfenverteilung und keine nachweisbare Metallverunreinigung auf und erf\u00fcllte somit vollumf\u00e4nglich die technischen Anforderungen des Kunden.<\/p>\n\n\n\n

Dieses Projekt demonstriert Episches Pulver<\/a>\u2019starke Expertise in Strahlm\u00fchlentechnologie, Aluminiumoxidmahlung und Verarbeitung von ultrafeinem Pulver<\/strong>, bietet zuverl\u00e4ssige und effiziente L\u00f6sungen f\u00fcr anspruchsvolle Materialanwendungen.<\/p>\n\n\n\n
