APPARATUS FOR CONTINUOUS FEEDING OF GRANULAR MATERIAL WITH SHARP CORNERS TO A CONVEYOR PIPE LINE

摘要

Apparatus for continuous feeding of granular material with sharp corners to a conveyor pipe line through which a compressed-gas carrier flows, includes a vertical cylindrical chamber with a bottom having a central discharge opening connecting with the pipe line and a top having a charging inlet for the material, means in the chamber at different levels acting to alternately lift and release successive portions of the material preventing the grains from interlocking and forming clumps due to their sharp corners. Also, means are provided for feeding the material to the discharge opening into the pipe line and stirring it while feeding through this opening. Other features are included.
