Abstract

En forbedret ovn for kalsinering av et pulver omfatter en direkte oppvarmet, roterbar ovn, hvor i det minste en del av den indre rundtgående vegg er utstyrt med flere fremspring. Fremspringene er formet slik at pulveret ikke i vesentlig grad løftes av fremspringene under drift av ovnen. I en fore- trukket utførelse har fremspringene form av et trekantformet prisme og befinner seg inne i selve ovnen for derved å kunne passere gjennom pulveret på samme måte som -en plog. Fortrin- nsvis har toppflaten på prismet form av en likebenet trekant, hvor de like vinkler er større enn rasvinkelen for det pulver som ovnen er beregnet for.
