Abstract
The pneumatic feeding device for a container balance includes a stationary feeding conduit for the loose material arranged above the container and directed substantially perpendicularly through an adjustable coupling piece into the interior of the container. To compensate for reaction forces resulting from the pneumatic operation of the feeding device, there is provided a pneumatic pressure compensator acting from the outside on the container in counter direction to the reaction forces.
Claims12
A pneumatic device for feeding loose material into a container-type balance, comprising:
- pneumatic feeding means including a pneumatic circuit in which the container of the balance is connected so as to be subjected to the pneumatic action in the circuit, a rigid feeding conduit arranged in said circuit for discharging the loose material from above into said container;
- and means for compensating reaction forces acting on said container due to the pneumatic feeding process.
