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 class=\"wp-block-image aligncenter size-large is-resized\"><img fetchpriority=\"high\" decoding=\"async\" width=\"1024\" height=\"768\" src=\"https:\/\/www.epicmicron.com\/wp-content\/uploads\/2025\/12\/IMG_20250729_154329-1024x768.webp\" alt=\"\" class=\"wp-image-16397\" style=\"width:860px;height:auto\" srcset=\"https:\/\/www.epicmicron.com\/wp-content\/uploads\/2025\/12\/IMG_20250729_154329-1024x768.webp 1024w, https:\/\/www.epicmicron.com\/wp-content\/uploads\/2025\/12\/IMG_20250729_154329-300x225.webp 300w, https:\/\/www.epicmicron.com\/wp-content\/uploads\/2025\/12\/IMG_20250729_154329-768x576.webp 768w, https:\/\/www.epicmicron.com\/wp-content\/uploads\/2025\/12\/IMG_20250729_154329-1536x1152.webp 1536w, https:\/\/www.epicmicron.com\/wp-content\/uploads\/2025\/12\/IMG_20250729_154329-2048x1536.webp 2048w, https:\/\/www.epicmicron.com\/wp-content\/uploads\/2025\/12\/IMG_20250729_154329-16x12.webp 16w, https:\/\/www.epicmicron.com\/wp-content\/uploads\/2025\/12\/IMG_20250729_154329-scaled-600x450.webp 600w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p>La materia prima era allumina ad alta purezza (Al\u2082O\u2083) con una durezza Mohs superiore a 9. Il cliente ha sottolineato l&#039;importanza di una lavorazione priva di contaminazioni e di una distribuzione granulometrica ristretta per garantire prestazioni a valle costanti. Dopo la valutazione tecnica, Epic Powder ha selezionato <strong>mulino a getto a letto fluido<\/strong>, che \u00e8 particolarmente adatto per <strong>macinazione di polvere ultrafine<\/strong> di materiali duri.<\/p>\n\n\n\n<p>Nel processo di produzione, l&#039;aria compressa viene prima filtrata ed essiccata prima di entrare nel sistema di macinazione a getto. La polvere di allumina viene immessa nella camera di macinazione, dove un flusso d&#039;aria ad alta velocit\u00e0 accelera le particelle. Il flusso d&#039;aria ad alta velocit\u00e0 provoca intense collisioni tra particelle per ottenere una riduzione granulometrica, anzich\u00e9 affidarsi all&#039;impatto meccanico. Un classificatore dinamico interno controlla con precisione la finezza finale e consente alle particelle ultrafini qualificate di uscire dal sistema, mentre il sistema restituisce automaticamente le particelle di grandi dimensioni per un&#039;ulteriore macinazione. Il sistema completamente chiuso garantisce un funzionamento pulito, stabile e affidabile.<\/p>\n\n\n\n<p>Dopo la messa in servizio e l&#039;ottimizzazione dei parametri, il sistema di mulino a getto ha raggiunto risultati di produzione stabili. Il prodotto finale ha raggiunto una granulometria di <strong>D97 = 2,07 \u03bcm<\/strong>, con una produzione costante di <strong>130 kg\/ora<\/strong>. La polvere di allumina ultrafine ha mostrato una distribuzione granulometrica ristretta e nessuna contaminazione metallica rilevabile, soddisfacendo pienamente i requisiti tecnici del cliente.<\/p>\n\n\n\n<p>Questo progetto dimostra <a href=\"https:\/\/www.epicmicron.com\/it\/products\/\">Polvere epica<\/a>\u2019la sua forte competenza in <strong>tecnologia di mulino a getto, macinazione dell&#039;allumina e lavorazione di polvere ultrafine<\/strong>, fornendo soluzioni affidabili ed efficienti per l&#039;applicazione di materiali di alta qualit\u00e0.<\/p>\n\n\n\n<h2 class=\"wp-block-heading has-medium-font-size\">Parametri tecnici:<\/h2>\n\n\n\n<p><strong>Materiale:<\/strong> Allumina<\/p>\n\n\n\n<p><strong>Dimensione delle particelle:<\/strong> D97 = 2,07 \u03bcm<\/p>\n\n\n\n<p><strong>Produzione: <\/strong>130 kg\/ora<\/p>","protected":false},"featured_media":16397,"template":"","meta":{"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","ast-disable-related-posts":"","theme-transparent-header-meta":"","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"set","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}}},"astra-portfolio-categories":[45],"astra-portfolio-other-categories":[],"astra-portfolio-tags":[],"class_list":["post-16396","astra-portfolio","type-astra-portfolio","status-publish","has-post-thumbnail","hentry","astra-portfolio-categories-fine-chemical"],"astra-site-call-to-action":"","astra-site-open-in-new-tab":0,"astra-site-open-portfolio-in":"new-tab","astra-site-url":"","thumbnail-image-url":null,"thumbnail-image-meta":{"alt":"","title":""},"lightbox-image-url":null,"portfolio-type":"page","portfolio-video-url":"","request_time":0.10218596458435059,"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v27.3 (Yoast SEO v27.3) -
