The weighing container has an inner container (1) which is suspended from a rigid e.g. metallic frame (2) with dustproof flexible sleeves (8,9) surrounding upper entrance ports (7) for components of a mixt., and lower exit ports (16,17) from which the contents are discharged into downpipes (18). The wt. of the frame is carried by e.g. three supports (3) with individual load cells (4). The middle of the container is pinched between rollers (10a,10b) driven together by pneumatic cylinders (11a,11b) and the portion (12) below the pinch is positioned above one or other exit port by a union (13) on a plate (14), which is moved horizontally sideways by another cylinder (15), which incorporates proximity indicators (21,22). |
