SYSTEM OF INTERNALLY BACKMIXING THE REACTIVE MASS IN A ROTATING CYLINDER REACTOR

The present invention relates to a system for backmixing the reactive mass in rotating cylinder reactors. Within this context, the present invention provides a system for internally backmixing the reactive mass in a rotating cylinder reactor (2), comprising a first set of drag baffles (27) designed to drag the reactive mass in a first direction, and a second set of drag baffles (28) designed to drag the reactive mass in a second direction opposite to the first direction, the first (27) and second (28) sets of drag baffles being internally positioned over the whole length of the rotating cylinder reactor (2). The system described above allows part of the reactive mass from a more advanced stage of the reactor to be mixed with another from a previous processing stage, homogenizing the temperature of the reactive mass and increasing the productivity of the reactor.
