Embodiment Construction
[0060] Unless otherwise stated, the same reference numerals denote the same objects in the various figures.
[0061] exist figure 1The plant shown in is a plant for the manufacture of tablets in which a powdered product is compressed into tablets. The device accordingly comprises a rotary press, in particular a rotary tablet press, arranged in a housing 11 , having a rotor driven in rotation by a rotary drive, the rotor comprising a plurality of receptacles 12 mold plate 10. The receptacles 12 can be formed, for example, by holes in the mold plate 10 . In addition, the rotor comprises a plurality of upper punches 14 and lower punches 16 which revolve synchronously with the die plate 10 . The upper punch 14 is axially guided in an upper punch guide 18 , while the lower punch 16 is axially guided in a lower punch guide 20 . The axial movement of the upper punch 14 and the lower punch 16 during the rotation of the rotor is controlled by the upper control cam element 22 and th...

The invention relates to a method for operating a mixing device of a plant in which a powdery product is processed into a finished product, to which different powdery products are fed, and to which the different products are mixed into a mixed product in the mixing device before being processed into the finished product, a product inlet mass flow into the mixing device and a weight of the product in the mixing device are measured, and the weight of the product in the mixing device and a product outlet mass flow out of the mixing device are predicted from the measured product inlet mass flow by means of a mathematical model, and correcting a prediction of the product discharge mass flow created by means of the mathematical model as a function of the measured weight of the product in the mixing device. The invention further relates to a system for operating a mixing device of a plant.
Description
technical field [0001] The invention relates to a method for operating a mixing device of a plant in which powdered products are processed into finished products, different products in powder form are fed to the mixing device, and the different products are The blended product is mixed in a mixing device before being processed into a finished product. The invention also relates to a system for operating a mixing device of a plant. Background technique [0002] In such plants, for example, powdered products are processed into tablets or capsules. Accordingly, the apparatus may for example comprise a tablet pressing machine or a capsule filling machine. Such plants usually have a plurality of product inlets for the powdered product to be processed in the plant. Furthermore, such plants usually have a mixing device in which the different products conveyed are mixed to form the product to be processed. The mixed product is then conveyed from the mixing device to a production...
