Abstract:
A pneumatic transport method for transporting a powder of a chargeable resin comprising the steps of:I. providing a stream of air; and then II. adding steam to the stream of air thereby producing an initial air-steam mixture; and then III. mixing the powder with the initial air-steam mixture thereby producing a powder-laden pneumatic stream; and then IV. conveying the powder-laden pneumatic stream to a zone where the powder is removed from the powder-laden pneumatic stream, thereby producing a powder-depleted stream; wherein the amount of steam added to the initial air-steam mixture is adjusted so as to meet the following relationship: 0Â° C.<(T1âˆ’K1)Â° C.&lE;60Â° C. wherein T1 is the temperature of the powder-depleted stream; and wherein K1 is the dew point of the initial air-steam mixture.
