Abstract
A pneumatic mixture which has a relatively high content of pulverulent materials in the propulsion air is formed in a single metering means. This mixture is propelled through a common primary pipe to a distribution head in which the mixture is divided into secondary currents which are delivered respectively to each of the injection points. A supercritical speed is imparted to the mixture in the distribution head.
