Abstract

Device for maintaining constant the contents level in a charging device upstream of a bulk consumer of material particularly synthetic material granules, comprises a separator connected to a blower conveyor consisting of a blower tube open at the top and a conveyor tube opening below, the blower conveyor functioning with a greater transport power than the requirements of the material and the pressure in the inlet zone being maintained not greater than the pressure in teh charging vessel. Allows material to be fed to an extruder or injection machine at a constant bulk density.
