PURPOSE:To increase the mixability in the low degree of packing by providing rotatably a rotor in the inside of a chamber of a casting and also providing at least one piece of projection to an inside surface of the above-mentioned chamber to constitute a closed type mixer. CONSTITUTION:A rotor 20 is rotatably provided to the inside of a chamber 11 of a casting 10 and at least one piece of projection 30 is provided to an inside surface of the chamber 11. The projection 30 is screwed and fitted to a screw hole pored towards the inside surface of the chamber 11 from the outside of the casing 10 and the amount to be projected from the inside surface of the chamber 11 can be properly controlled by turning the projection 30 in the prescribed direction. By such a constitution, the sliding resistance between the compounds and the inside surface of the chamber 11 can be increased and the mixability and the dispersion properties can be remarkably increased. |
