Abstract

Husillo (27) que comprende un eje (39) del husillo que tiene un filete de rosca (41) que está posicionado helicoidalmente en torno al eje (39) del husillo formando una pluralidad de roscas, teniendo dicho husillo (27) una zona de alimentación (29), una zona de compresión (31) y una zona de dosificación (33), estando la profundidad, la anchura y el paso de las roscas (43) en la zona de alimentación (29) diseñados sobre la base de la densidad aparente del material a usar en el husillo (27), y estando la profundidad, la anchura y el paso de las roscas (47) en la zona de dosificación (33) diseñados sobre la base de la densidad en estado de fusión del material a usar en el husillo (27), para así obtener un caudal volumétrico real de material y un caudal volumétrico teórico de extrusión de material en la zona de alimentación (29) y un caudal volumétrico real de material y un caudal volumétrico teórico de extrusión de material en la zona de dosificación (33) tales que la diferencia entre la relación del caudal volumétrico real de material al caudal volumétrico teórico de extrusión de material en la zona de alimentación (29) y la relación del caudal volumétrico real de material al caudal volumétrico teórico de extrusión de material en la
