摘要:
The furnace comprises a tubular inner chamber for the treatment of the raw material, mounted inside the enveloping body of the furnace which is insulated from the exterior and is provided with internal resistor systems for heating the chamber of the furnace by radiation, comprising means for feeding raw material at one end and means for controlling the output of completed product at the other end of the treatment chamber of the furnace, inside which a worm screw, driven in rotation from the exterior, is mounted rotatably, respective percussion devices being incorporated in the ends of the screw to prevent compaction of the mass on the screw.
摘要:
The furnace comprises a lower heating chamber (1) and an assembly of treatment chambers in the form of tubular elements (3,4,5,6) substantially parallel to one another, arranged horizontally one above the other and having means for feeding raw material (12) into the upper tubular element and means (13,15,17,19) for discharging each of the individual tubular elements to the adjacent lower tubular element, and also means (21) for extracting the finished product from the lower tubular element, enabling the movement in cascade of the raw material fed into the upper tubular element, passing successively to the lower tubular elements, the assembly of tubular elements being contained within a single encasing body (2) which receives the heating gases from the lower heating chamber (1).
