AN EQUIPMENT FOR CALCINATION

摘要

An equipment for calcination for precalcining of powdered materials before their burning in a sintering equipment is inserted between the last but one cyclone (72) of connected cyclone exchanger (7) and the mixing channel (2), arranged over the input chamber (31) of connected rotary kiln (3) and connected to the input to the last cyclone (71) of cyclone exchanger (7) and it is composed from calcinating chamber (1), which have three parts-a working part (10), to which are connected the at least one air tube (6) and the at least one fuel input (5) and where this working part (10) and/or air tube (6) are further provided with input (4) of powdered material, and the upper part (11), which is provided with at least one interconnecting tube (110) serving for interconnecting with mixing channel (2) and lower part (12), which is provided with a removal tube (120) for interconnecting with the mixing channel (2). There is an input (4) of powdered material into the air tube (6) close to its mouth (600) to the calcinating chamber (1), eventually there is an auxiliary input (41) of powdered material and an auxiliary fuel input (51) additionally added into the air tube (6). Also the mixing channel (2) is advantageously equipped with additional input (42) of powdered material and with it connected additional fuel input (52) and with additional air tube (62).
