Den roterande torken anv\u00e4nds ofta f\u00f6r att torka kalksten. Efter gruvdrift inneh\u00e5ller kalksten vanligtvis en viss m\u00e4ngd fukt. Om den anv\u00e4nds direkt kan det p\u00e5verka senare bearbetningseffektivitet och produktkvalitet. <\/p>

Eftersom kalksten \u00e4r en viktig r\u00e5vara f\u00f6r att tillverka cement, kalk-pulver och andra byggmaterial anv\u00e4nds roterande torkar i stor utstr\u00e4ckning f\u00f6r dess torkning. S\u00e5, hur hanterar den roterande torken kalkstens torkning?<\/p>

Kalkstens torkprocess med en roterande tork<\/a><\/strong><\/h2>

Matning och transport<\/h3>

Kalkstenen levereras f\u00f6rst till torkens matningstillopp via en transport\u00f6r. F\u00f6r att s\u00e4kerst\u00e4lla smidig matning \u00e4r matningsr\u00f6ret vanligtvis inst\u00e4llt i en vinkel n\u00e5got st\u00f6rre \u00e4n kalkstenens naturliga v\u00e4ndningsvinkel, vilket g\u00f6r kontinuerligt inmatningar och fram\u00e5tr\u00f6relse inuti trumman m\u00f6jligt.<\/p>

Torkning inuti trumman<\/h3>

Roterande trumma lutar n\u00e5got och roterar l\u00e5ngsamt. Under verkan av rotation och inre lyftplattor forts\u00e4tter kalkstenen att tumla och blandas. Under torkningen \u00f6verf\u00f6rs v\u00e4rme till kalkstenen antingen av direkt hetluftfl\u00f6de eller genom den uppv\u00e4rmda trumv\u00e4ggen, vilket g\u00f6r ytfukten snabbt avdunstas.<\/p>

V\u00e4rmev\u00e4xling med varm luft<\/h3>

Den varma luften i torken kommer i full kontakt med den roterande kalkstenen och b\u00e4r med sig fukt. Genom att justera trummans hastighet, lutning och h\u00f6g temperatur kan olika kapaciteter och torkniv\u00e5er uppn\u00e5s.<\/p>

Efter torkning direktionsutsl\u00e4pp<\/h3>

Efter skakning och uppv\u00e4rmning under en best\u00e4md tid n\u00e5r kalkstenen den \u00f6nskade fuktniv\u00e5n och t\u00f6ms smidigt fr\u00e5n utloppet i slutet av trumman.<\/p>
