METHOD AND DEVICE FOR FEEDING BULK MATERIAL THROUGH A PNEUMATIC CONVEYING LINE

摘要

Method and device for feeding bulk material through a pneumatic conveying line (10) having an inlet end (12) and an outlet end (14), wherein bulk material is fluidised at the inlet end by adding conveying gas to form a fluidised material flow. The fluidised material flow is split into a first partial flow and a second partial flow at a first junction (20) located near the outlet end of the pneumatic conveying line. The fluidised material from the second partial flow is fed through a separation device (26) to separate conveying gas from bulk material. The bulk material recovered from the separation device (26) is then fed into the first partial flow at a second junction (40) located downstream of the first junction (20).
