ABSTRACT A process and apparatus for pneumatically conveying solid particulate material which includes a vessel or blow tank which is supplied with particulate material to be conveyed from a suitable source. A riser pipe extends into the vessel and has a material inlet near the bottom of the tank with its other end flow connected to a transport line. A bottom discharge arrangement is also contemplated. Gaseous fluid under pressure is supplied into the vessel to pressurize the vessel and entrain and convey material through the riser pipe to the material transport line and to a remote use point. A by-pass line is provided for selectively connecting the pressurized inside of the vessel with the riser pipe/transport line at a point downstream of the inlet for material. This by-pass line serves to selectively vent gaseous fluid under pressure in the vessel to the material conveying line when system pressure exceeds a predetermined limit. This results in an increase in air flow being supplied to the conveying line to thereby reduce the material to air ratio in the conveying line and control the conveying rate through the conveying line. Adjustment of the value of the predetermined pressure can be used to adjust the material conveying rate. A low level sensor is provided in the vessel for actuating a control mechanism to change the predetermined pressure at which the by-pass line will open to thereby permit gas under pressure in the vessel to be used for emptying the vessel.
