ABSTRACT:
A method of self regulation of a pneumatic conveyor of pulverulent material comprising a feed column at the foot of which is formed a talus, a forwarding chamber provided with a porous fluidization wall, tubes for fluidization and for supply of gas at super pressure, and conveying tubes in which a set pressure Pf is selected below the porous wall for a desired flow of material in the forwarding column, in that a pressure Pc is established above the said wall in the forwarding chamber so that a reduction in the circulation of gas at the pressure Pf through the porous wall corresponds to any increase of Pc beyond Pf while an increase in the said circulation of gas corresponds to any reduction in Pc below Pf.
