ABSTRACT:
This invention relates to apparatus for the pipe transport of material comprising non-slurried solids particles by means of a pipe which is generally upright. The material to be transported and also air are introduced at the top of the pipe. In order to prevent plug-up of the pipe the material and air flow rates are controlled by means of a central processing unit. A plurality of monitors located along the length of the pipe provide to the central processing unit signals indicative of the pressure in the pipe at the various locations.
