Par cons\u00e9quent, pour r\u00e9pondre \u00e0 la demande de poudres ultrafines, le broyage \u00e0 sec n&#039;est peut-\u00eatre pas la meilleure solution.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Consommation et co\u00fbt de l&#039;\u00e9nergie<\/h2>\n\n\n\n<p>Comme les exigences pour <a href=\"https:\/\/calcium-carbonate.epic-powder.com\/fr\/machines\/\">carbonate de calcium<\/a> L&#039;augmentation de la granulom\u00e9trie de la poudre entra\u00eene une augmentation significative de la consommation \u00e9nerg\u00e9tique du broyage \u00e0 sec.

Cela constitue un d\u00e9fi pour les applications n\u00e9cessitant un contr\u00f4le pr\u00e9cis de la distribution granulom\u00e9trique.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Forme des particules<\/h2>\n\n\n\n<p>Les particules de calcium lourdes obtenues par broyage \u00e0 sec pr\u00e9sentent une forme irr\u00e9guli\u00e8re et des ar\u00eates et des angles prononc\u00e9s.

Cela n\u00e9cessite un entretien r\u00e9gulier et le remplacement des pi\u00e8ces, ce qui augmente les co\u00fbts de maintenance.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Probl\u00e8mes environnementaux<\/h2>\n\n\n\n<p>Le broyage \u00e0 sec peut g\u00e9n\u00e9rer davantage de poussi\u00e8re, ce qui peut nuire \u00e0 l&#039;environnement et \u00e0 la sant\u00e9 des travailleurs.
