In a device ( 1 ) for heating primary materials, in particular calcined petroleum cokes ( 5, 6 ) from which an anode ( 4 ) can be manufactured for dry electrolysis, comprising a mixing and forming unit ( 8 ) in which the primary materials ( 5, 6 ) can be formed into anodes ( 4 ) which are subsequently fired in an annular anode furnace ( 3 ), the thermal waste heat of the annular anode furnace ( 3 ) should be usable for heating up the primary materials ( 5, 6 ). This is achieved in that the primary materials ( 5, 6 ) can be heated in a heat exchanger ( 11 ) by means of flue gas drawn from the annular anode furnace ( 3 ) through a feed pipe ( 12 ), and that the petroleum coke fractions ( 5, 6 ) heated in this way can be input into the mixing and forming unit ( 8 ) for forming the unfired anode ( 4 ).
