An apparatus for dispersing and melting flowable substances has axis-parallel supporting shafts ( 1, 2 ) rotatable in the same direction on which screw elements ( 3, 3 ') with the same direction of thread are fitted so as to rotate in unison, with which the shafts mesh. The screw elements ( 3, 3 ') consist of screw portions ( 11, 12, 13, 14; 11', 12', 13', 14 ') that are disposed at a progressive angular offset from each other with the same sense of rotation so as to form faces ( 15, 16; 15', 16 ').
