APPARATUS FOR AUTOMATIC REGISTRATION OF A CONTINUOUS BULK MATERIAL FLOW BY MEANS OF A RUN-THROUGH WEIGHING DEVICE
The apparatus includes a run-through weighing device (1) consisting of a weighing barrel (6), an adjustable shut-off device (4) for adjusting the exit diameter of the weighing barrel (6) in addition to electronic weight-difference measurement facilities. The shut-off device (4) is in the outlet area of the weighing barrel (6), and connected to the latter by means of a movable partition component, so arranged that when the shut-off device is in open operational position, the bulk material flows freely. At the same time, care is taken to ensure that the flow of loose bulk material from the outlet section of the weighing barrel (6) is unobstructed. In a process to permit automatic registration of the loose bulk material flow in an apparatus of this kind, a suitable signal is sent off and used for the calculation of state parameters of the bulk material for each change in weight occurring per time unit, either when a mass material flow occurs in the entire weighing barrel (6) or when the flow of mass material is totally stopped.
