1. Kalcineringsmetod för frän jorden utnyttjande jordämne, mineral eller stenämne, där kalcinerande ämne torkas och uppvärms över kalcineringstemperatur sä, att i ämnet liggande kristallvatten löser sig, kännetecknad därav, att det kalcinerande ämnet leds till trycklig arbetsgas, som fas frän en kompressor (1) i pulverisering (2), vilken gas tidigare 10 blev varmare i pressning gjord av kompressoin (1) och med hjälp av värmeenergi av nämnda arbetsgas förvärmes tili kalcineringen ledande fatt gas/solid ämnesblandning, varvid kalcineringens krävande sluttemperatur uppnäs genom att leda frän uppvärm-ningsenheten (4) ledd brandgasströmning i en apparat (3) för att mötas och förenas med nämnda gas/ solid ämnesblandning, varvid det kalcinerad solid ämnet slutligen avskiljas 15 frängas.
2. Metod enligt patentkrav 1, kännetecknad därav, att kalcineringsprocessen hälles i undertryckt läge med hjälp av sugning av en fläkt (7).
3. Metod enligt patentkrav 1, kännetecknad därav, att efter kalcineringen det leds kylningsluft till gas/ solid ämnesblandningen via en ventil (5).
4. Metod enligt patentkrav 1, kännetecknad därav, att arbetsluft frän kompressom (1) tili processen leds utan kylning. 25
5. Metod enligt patentkrav 1, kännetecknad därav, att kalcineringstemperatur är över 600°C. 30 35
