Improvement in rotary kiln used for calcination of gypsum with heating semidireto

摘要

Improvement in rotary kiln, used for calcination of gypsum with heating semidireto, with means for loading and unloading of the gypsum dehydrated gypsum.Creating internally to the furnace (1), heating zones semidireto through the placement of tubes (11) which cross at right angles to the larger of the furnace (1),Allowing the passage of the heat contained in the insulating chamber (2), generated by burners (4) through the openings (18).As defined in point of union between the tubes (11) and the external wall of the furnace (1), said tubes (11) positioned in the oven (1) diametral direction, mounted on an angle of 90 degrees with each other and,With the fins (12) for a better heat distribution.The system also has time sensors (14) to enable the control of load of gypsum to be dealt with by the opening and closing of the feeder (6),And temperature sensors (13) formed by thermocouples to allow the drive of the unloading when it reached the final stage of calcination.
