Abstract

A rotating mixer with a double-cone mixing vessel carried by a horizontal mixer spindle, the mixing vessel consisting of two identical half-vessels which are releasably clamped to a central spindle ring. The opening of the spindle is closable by means of a pivotable shutoff clappet, when the charged half-vessels are attached or released using a dolly and lifting jack. Separate pairs of half-vessels can be used for mixing charges of different composition.

Claims

1. Double-cone rotating mixer, the double cone mixing container of which is rotatable about a horizontal rotational axis, aligned at a right angle to the container axis, characterized by the following features:

(a) the mixer spindle (3'"'"') carries a ring (6);

(b) the ring (6) possesses on its front faces two ring clamping areas (7,7'"'"') with clamping devices (8,8'"'"');

(c) a closing valve (10), adapted to the inner cross-section of the ring, is pivotable about a swivelling axis (9);

(d) two half containers (14,14'"'"') each comprising a contact surface (18), suited for one of the ring clamping areas (7,7'"'"'), as well as a conical bottom part (16).

2. Double-cone rotating mixer according to claim 1, characterized by a lifting device (12) for said half container.

3. Double-cone rotating mixer according to one of claims 1 or 2, characterized in that the ring (6) is supported on the mixer spindle (3'"'"') in a cantilevered arrangement.

4. Double-cone rotating mixer according to claim 1, characterized in that the closing valve (10) is pivotable over an angle of almost 90°

.

5. Double-cone rotating mixer according to claim 1, characterized in that the swivelling axis (9) of the closing valve (10) is aligned approximately perpendicularly to the mixer spindle (3'"'"').

6. Double-cone rotating mixer according to claim 1, characterized in that there is a lockable outlet device (17) in the bottom part of each half-container (14,14'"'"').
