Abstract
An operating process for the formation of a steady particle stream of particles which are conveyed within a flow conduit through the intermediary of a flow medium, and which are introduced into the medium flow under the effect of gravity through an infeed conduit discharging into the flow conduit. The invention also includes an arrangement for the effectuation of the process. A partial flow of the flow medium from the flow conduit is introduced into the infeed conduit in a direction counter to the flow direction of the particles, and is regulated in the manner so as to set the desired particle flow. The volumetric flow of the flow medium which streams counter to the particles in the infeed conduit can, in an advantageous manner, be regulated externally of the infeed conduit whereby no regulating devices will be located in the flow path of the particles.
