Abstract
A method and device for pneumatically transporting bulk material including a plurality of supply elements spaced along a conveyor line. These elements provide an additional gaseous medium as a booster fluid. The supply elements are automatically and individually controlled via velocity measurements taken near the elements.
Claims16
A method for pneumatically transporting bulk material through a conveyor line from an inlet to an outlet, comprising:
- forcing the material into the line using a pressurized gaseous medium;
- introducing additional pressurized gaseous medium into the conveyor line through supply elements connected to the conveyor line at connection points between said inlet and said outlet;
- measuring the velocity of the material through the conveyor line near the connection point of each supply element;
- and
- automatically controlling the introduction of pressurized gaseous medium via the respective supply element in dependence on the velocity that is measured.

A device which pneumatically transports bulk material, comprising:
- a pneumatic conveyor line having an inlet and an outlet;
- means for forcing said bulk material into the line by flow of a pressurized gaseous medium;
- a plurality of supply elements connected to said conveyor line at points between said inlet and said outlet, which supply elements function to introduce additional pressurized gaseous medium into the conveyor line;
- a measuring element which measuring the velocity of the material through the conveyor line disposed near the connection point of each supply element to the conveyor line, and
- means for adjusting the supply element in dependence on the velocity detected by said measuring element, said adjusting means disposed between the supply element and the respective measuring element.
