PURPOSE: To have continuous transport of pulverized substance at constant rate stably by simple construction by installing a supplying machine to supply the pulverized substance to the lower part of a pressurization tower at a constant rate, and by transporting the pulverized substance sent from this supplying machine by pneumatical means in the form of mixture with pressurized gas prepared by a mixer.

CONSTITUTION: A pressurization tower 11 in the form of a hollow cylinder is installed upright, to store pulverized substance, wherein a shutoff pressure shall be generated by the own weight of this pulverized substance. A hopper 12 for supply of the pulverized substance is installed at the top of this pressurization tower 11, and the lower part shall have a diameter a little reduced to serve for connection to the cast-in hole of a screw type supplying machine 13. An agitator 14 of screw type is installed inside the pressurization tower 11 in order to prevent the substance from bringing about clog inside the tower 11. A mixer 15 is installed at the discharge hole of said supplying machine 13 to mix pulverized substance sent from the supplier 13 with high pressure air. Thus the substance can be transported pneumatically by high pressure air.
