The device includes a disc-like cavity to which the powder is supplied and where the supplied powder is classified, a powder supply port for supplying the powder to the cavity, guide vanes arranged so as to extend from an outer periphery of the cavity in an inner direction at a predetermined angle, a discharge unit for air streams including fine particles discharged from the cavity, a collection unit for coarse particles discharged from the cavity and air nozzles arranged below the guide vanes on an outer peripheral wall of the cavity along a tangential direction of the outer peripheral wall and blow compressed air into an inside of the cavity. | 10-28-2010 |
| 20110272330 | Air Sifting or Separating Machine Having Discharge Regulation - An air sifting or separating machine for dry separation of raw material, including a carrier member having openings and receiving material to be sifted or separated from a material feed mechanism, and a discharge mechanism for heavy material and light material layered on the carrier member during a sifting process. A pulsating air stream is passed through the carrier member to loosen up and layer the material fed to it. A control device for the discharge mechanism is operative via radiometrical measurement of the thickness of the material, and is comprised of a source of radiation mounted on a wall of the machine, and an associated scintillation unit that measures absorption of radiation given off by the source of radiation. The scintillation unit is disposed within a protective pipe freely mounted at a suitably set distance from the source of radiation and within a sifting or separating bed formed by the heavy material layer. The protective pipe is carried by the support mechanism connected to the machine and extending over the carrier member. | 11-10-2011 |

| 20130220893 | APPARATUS AND METHOD FOR PROCESSING BAGGED REFUSE - A method of processing bagged refuse includes pneumatically conveying filled refuse bags along a conduit using an airflow and opening the bags during the pneumatic conveyance. An apparatus for carrying out the method includes a conduit configured to pass an airflow to pneumatically convey bagged refuse along the conduit and a bag opening structure arranged to open the refuse bags during pneumatic conveyance along the conduit. The open bagged refuse is sorted into fractions using the airflow by passing the refuse across an opening through which the airflow continues. A wall is arranged in the path of travel of the pneumatically conveyed refuse to disaggregate the refuse by impacting the refuse against the wall. The wall is arranged vertically and at least partially defines an opening through which the air stream continues such that a fraction of the refuse falling across the opening is conveyed through the opening. | 08-29-2013 |

| 20100163465 | METHOD AND APPARATUS FOR DIVIDING A STREAM OF SOLIDS - A method for dividing a stream of solids includes discharging the stream of solids via a first downer. The stream of solids are fluidized at a bottom of the first downer by supplying a first conveying gas. By the first conveying gas, a part of the stream of solids are conveyed to a top of a first riser branching off from the first downer. A remaining part of the stream of solids are discharged via a second downer adjoining the first downer. The remaining stream of solids are fluidized at a bottom of the second downer by supplying a second conveying gas. By the second conveying gas, a part of the remaining part of the stream of solids are conveyed to a top of a second riser branching off from the second downer. | 07-01-2010 |
