Abstract
There as herein defined a pneumatic conveying system comprising a cyclonic feed apparatus. In particular, there is described a pneumatic conveying system comprising a vessel (e.g. a cyclonic separator) in combination with a sifting device (e.g. a centrifugal device) which is capable of separating pneumatically conveyed material into oversize powder discharge (e.g. waste material) and fine powder discharge (e.g. valuable product material).
Claims21
An apparatus (500) for pneumatically conveying and separating bulk material comprising:
- a vessel (526) for receiving and separating gas and bulk material, wherein the vessel (526) comprises a gas outlet (572);
- at least one material inlet (512) located on the vessel (526) configured to input gas and bulk material into the vessel (526) at a rate of 5 m/s to 100 m/s and thereby form a cyclone which separates the gas and bulk material within the vessel (526);
- a sifting device (534) for receiving the bulk material from the vessel (526), wherein the sifting device (534) comprises a first sifter outlet (546), wherein bulk material is separated via centrifugal forces into at least two or more different powder discharges;
- and
- a pneumatic air conduit (570) directly connected with the gas outlet (572) and the first sifter outlet (546), wherein the pneumatic air conduit (570) is configured to provide uninterrupted gas flow to the first sifter outlet (546).
2 more elements
A method of conveying and separating bulk material comprising:
- providing a vessel (526) for receiving and separating gas and bulk material, wherein the vessel (526) comprises a gas outlet (572);
- providing at least one material inlet (512) located on the vessel (526) configured to input air and bulk material into the vessel (526) at a rate of 5 m/s to 100 m/s and thereby forming a cyclone which separates the gas and bulk material within the vessel (526);
- providing a sifting device (534) for receiving bulk material from the vessel (524), wherein the sifting device (534) comprises a first sifter outlet (546), wherein the sifting device (534) separates the bulk material via centrifugal forces into at least two or more different powder discharges;
- and
- providing a pneumatic air conduit (570) directly connected with the gas outlet (572) and the first sifter outlet (546), wherein the pneumatic air conduit (570) is configured to provide uninterrupted gas flow to the first sifter outlet (546).
