Abstract

Uunia ja menetelmä kiinteän epäorgaanisen materiaalin (16) lämpökäsittelemiseksi. Uuni käsittää pyöritettävissä olevan vaipan (2) määrittelemän uunitilan (1), vaippaa ympäröivät lämmityselimet (3) lämmön tuomiseksi uuniin vaipan (1) läpi, uunin ensimmäiseen päädyssä (4) olevan syöttöaukon (6) materiaalin syöttämiseksi uuniin ja uunin toiseen päätyyn (5) järjestetyn poistoaukon (7) lämpökäsitellyn materiaalin poistamiseksi. Keksinnön mukaan syöttöaukon (6) suhteen vastakkaiseen päätyyn (5) on järjestetty uunitilan (1) sisälle ulottuva kaasun kuumennin (8), joka käsittää virtauskanavan (8’), johon on tuotavissa lämpöä virtauskanavassa (8’) virtaavan kaasun kuumentamiseksi ja uuniin syötettävän materiaalin (16) lämpökäsittelyn tehostamiseksi. Uuni soveltuu mm. mineraalisten materiaalien, kuten spodumeenin, lämpökäsittelemiseksi.An oven and a method for heat treating a solid inorganic material (16). The furnace comprises a furnace space (1) defined by a rotatable diaper (2), heating elements (3) surrounding the diaper to introduce heat into the furnace through the diaper (1), a feed opening (6) at the first end (4) of the furnace and an outlet (7) provided for removing heat-treated material. According to the invention, a gas heater (8) extending inside the furnace space (1) is provided at the opposite end (5) of the inlet (6), comprising a flow passage (8 ') for supplying heat to heat the gas flowing in (16) to enhance heat treatment. The oven is suitable for eg. for heat treatment of mineral materials such as spodumene.
