ABSTRACT:
A method and apparatus for pneumatic feeding of additives along pipes from an additive silo to converters. The additive is allowed to flow into a dispatching device, a scale or a similar device in it stopping the entrance of the additive when the desired quantity of additive has arrived in the dispatching device. The dispatching device is pressurized thereafter by means of compressed air, by means of which the quantity of additive is fed via a pipe into the converters.
