PROCESS FOR FEEDING A SECOND STREAM OF PULVERULENT MATERIALS INTO A PNEUMATIC CONVEYING LINE CARRYING A FIRST CONTROLLABLE FLOW OF PULVERULENT MATERIALS

摘要

The present invention relates to a process for feeding a second stream of pulverulent materials into a pneumatic conveying line carrying a first controllable flow of pulverulent materials. The second stream of pulverulent materials is fed at a controlled rate and the control of the first flow is rendered insensitive to disturbances caused by the feeding of the second stream by directly or indirectly controlling the first flow upstream of the injection point of the second stream.
