Claim Text:
1. A conveyor for transporting powder including dust from an inlet point to at least one discharge point, the conveyor comprising: a fluidized bed transport duct for receiving powder including dust fed at the inlet port; a fluidization gas supply space for supplying fluidization gas to the fluidized bed transport duct to fluidize the powder in the fluidized bed transport duct for transporting the powder to the at least one discharge point downstream of the fluidized bed transport duct; a gas outlet transport duct bypass for removing fluidization gas from the fluidized bed transport duct; means for separating dust from the removed fluidization gas in the gas outlet transport duct bypass, the means for separating dust including an inlet for receiving dust laden gas, a first outlet for collecting the dust from the dust laden gas, and a second outlet for collecting de-dusted gas having the dust separated therefrom; and means for merging the separated dust with the fluidized power by the first outlet which is arranged proximate the discharge point, wherein the means for separating dust mixes the separated dust back into the powder in a mixing region in a lower portion of the means for separating dust.
