Methods, systems, and apparatus for winnowing. In one aspect, a method includes loading an initial material into a winnowing system via a feed member; feeding the material into a fluidically accelerated winnowing cavity, where the initial material impacts at least one plate member to yield chaff material and processed material, and where the processed material and the chaff material circulate in the winnowing cavity; and separating the chaff material and the processed from the winnowing cavity based on density. Other aspects include yielding intermediate material, where the intermediate material reimpacts the at least one plate member until yielding chaff material and processed material, preprocessing the initial material, controlling the flow of initial material into the winnowing cavity with a feed gate, where the chaff material egresses the winnowing cavity via a chaff chute, where the chaff material collects in a collection cavity, and/or more.

A sifter serves for separating coarse particles from a particle-carrying stream during the manufacture of wood material panels, in particular wood fiber panels. The sifter has a housing forming a chamber and having a material inlet for admitting the particle-carrying stream to the chamber, at least one air inlet below the material inlet for admitting an air stream to the chamber, an exhaust-air outlet for conveying air and fine particles from the chamber, and a coarse-particle outlet for conveying coarse particles out of the chamber. An upper front wall of the housing above the air inlet is oriented at least partially at an angle to the vertical. An upper edge of the air inlet is either vertically aligned above a lower edge of the air inlet or projects by an amount beyond the lower edge into the chamber.

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.

The invention provides, inter alia, a method for producing granules from a powder, characterized in that compaction force is applied to the powder to produce a compacted mass comprising a mixture of fine particles and granules and separating and removing fine particles and/or small granules from the other granules by entraining the fine particles and/or small granules in a gas stream. Also provided are apparatus for use in the process and tablets formed by compression of the resultant granules.

A mass transfer system including a housing and a three-dimensional ordered open-cellular micro-truss material within the housing for a mass transfer application. Here, the three-dimensional ordered open-cellular micro-truss material includes a plurality of first truss elements defined by a plurality of first self-propagating polymer waveguides and extending along a first direction, a plurality of second truss elements defined by a plurality of second self-propagating polymer waveguides and extending along a second direction, and a plurality of third truss elements defined by a plurality of third self-propagating polymer waveguides and extending along a third direction. The first, second, and third ordered truss elements interpenetrate each other at a plurality of nodes to form a continuous material. In one embodiment, the continuous material is a metal material.

A dedusting apparatus is formed with a rectangular inlet structure that assures a fully loaded feeding of particulate material over the face of the opposing wash decks. A rectangular inlet box having substantially the same width dimension as the corresponding dimension of the adjacent wash decks provides an even distribution of particulate material over the entire surface of the wash decks. A reconfiguration of the air inlet structure eliminates a rearward air plenum and manifold by passing the air flow upwardly through the bottom wall of the apparatus housing, rather than through the rear wall. Individually adjustable inlet deflectors can regulate the product flow on each respective wash deck and can be closed to stop the product flow completely to either one or both of the wash decks. Actuators control the movement of the deflectors, which can be integrated in an overall electronic control system for the dedusting apparatus.

The invention hereby disclosed is a vertical filtering and separating suction machine of chips, steam and smoke for machining center, lathe machine or other machines, which operates by sudden changes of sucked air, thus generating hits which separate heavy particles, whose suction pipe extends almost up to the bottom of the rotor, which only uses filters at the end of the process of air purification, whose rotor has outer paddles modified in order to improve suction power and to cause more hits of air flow, and which includes an air pressure alarm showing the filter is saturated.
摘要:
An axial classifier for separating the particles of a fluid flow based on the size of the particles. The classifier includes an inlet pipe having a first end and a second end wherein the first end receives the fluid flow from another device and the second end outputs the fluid flow, a reclaim pipe having an opening configured to receive the particles separated from the fluid flow, a reflecting cover provided above the inlet pipe for redirecting the fluid flow exiting the inlet pipe toward the reclaim pipe, and a housing forming a chamber for the fluid flow to flow therein, wherein the housing includes an opening for the fluid flow to exit the classifier. The second end of the inlet pipe is provided above the opening of the reclaim pipe, wherein the particles of the fluid flow are separated in the chamber after existing the reflecting cover.
