Problems solved by technology

[0012] The agitator described above has a fixed helix angle, so that, despite the improvements, it necessarily operates in a constant manner in all areas of the mixing chamber where it flows; therefore it is not possible to achieve dispersive mixing simultaneously throughout the entire flow field of the mixing chamber and uniform mixing for best results

Embodiment Construction

[0027] As shown, the closed mixer 1 comprises a top loading part 1a, a mixing chamber 2 and a base 1b with a hatch 20; the hatch 20 is used to open the mixing chamber so that when the mixing cycle is terminated Dump the mixture out.

[0028] The mixing chamber 2 is successively composed of two walls 3a, 3b and two supporting bosses (only 4b is visible in Fig. 1); Thus, the mixing chamber is divided into two half-chambers 2a, 2b, which house a respective agitator 5, which in the embodiment is of the tangential type and rotates about a respective longitudinal axis 5a, 5b.

[0029] The agitator 5 is basically cylindrical, with a total length L and a diameter D5; but it is divided into two independent sections along the longitudinal direction, one of which is L1, which is longer and constitutes the pushing blade 6 of the mixture; and the other section is L2, which is longer. Short, constitutes the balance blade 7 of the mixture.

[0030] Moreover, two agitators 5 are respectivel...

Abstract

Rotor for machines mixing elastomers and the like, comprising a first section of greater axial length (L1), defining a thrusting flange (6), and a second section of smaller axial length (L2), defining a counter-thrusting flange (7), in which at least one of said thrusting flange (6) or counter-thrusting flange (7) has an angle of entry ( beta , sigma ) into the mixture, which is varied along its extension.

Description

technical field [0001] The invention relates to a stirrer for a mixer for stirring materials such as elastomers. The agitator includes a first section with a longer axial length forming a pusher chime; and a second section with a shorter axial length forming a balancing chime. Wherein, at least one segment of the above-mentioned pushing flange or balancing flange has a cutting angle of entering the mixture that varies along the extension of the segment of the flange. Background technique [0002] It is known in the field of rubber and plastics processing to use mixers of the so-called "closed mixer" type in order to obtain a mixture suitable for the manufacture of finished or semi-finished products. The mixer is internally provided with a mixing chamber (divided into two half-chambers). Two agitators with parallel axes rotate in the two half-chambers. The two agitators can be tangential or intersecting. [0003] The basic functions of the above-mentioned agitator are to co...
