The invention relates to a screening device and a method for screening powders. The device comprises a screening space comprising a first chamber and a second chamber, which chambers are arranged adjacent and have a common partition wall. The device comprises a screen which is placed obliquely or vertically in the screening device, wherein the screen forms at least a part of the common partition wall. The first chamber comprises a raw material inlet, a drive gas inlet, a float gas unit, and a residual particle outlet. The second chamber comprises a product material outlet and a rotatable blade, wherein the blade comprises nozzles which are configured for blowing gas against the screen. In addition, the invention relates to an assembly comprising a first and second screening device, wherein the product material outlet of a first screening device is connected to the raw material inlet of the second screening device.

A separator having a housing, a feed cone and a rotatable dispersing plate, on the upper face of which dispersing blades which are distributed across the periphery of the dispersing plate are arranged. The feed cone is arranged on the housing at a distance from the dispersing plate. The precision of the separator is improved compared to conventional separators.

A separating device for separating different material fractions out of a feed-material mixture having a flow channel, which has a slope, extends in parallel with the direction of gravity in particular in its main longitudinal extension direction and comprises an inner chamber. The separating device has a first end region, a second end region, a material inlet region intended for feeding the feed-material mixture into the inner chamber of the flow channel, an outlet through which an air stream containing a lightweight material can exit the flow channel, at least one conveying means that conveys air through the flow channel, and a cross-flow device that has a separation chamber and an air intake that leads into said chamber and through which the cross-flow device can introduce air into the separation chamber in a flow direction extending at an angle to the main longitudinal extension direction of the flow channel.

A compactly configurable device that classifies material containing fiber can more reliably recover classified content. A classifier has a mesh disc with numerous holes, and separates screenings that pass through the holes from remnants that do not pass through; a defibrated material spray nozzle disposed to one side of the mesh disc sprays defibrated material containing fiber onto the mesh disc; a suction conduit disposed to the other side of the mesh disc suctions the waste screenings that pass through the holes; and a recovery conduit disposed on the one side of the mesh disc suctions the processing feedstock that do not pass through the holes and in the mesh disc and remain on the mesh disc. The mesh disc is disposed so the a position of the holes can move from a spraying position opposite the defibrated material spray nozzle to a suction position opposite the recovery conduit. The recovery conduit suctions, at the suction position, processing feedstock that was left at the spraying position.

A system to automate the separation of agricultural products. The system includes an enclosure, sealed with permeable mesh to permit airflow and walled with non-porous material to prevent agricultural material from escaping the enclosure while allowing for flow to pass freely. This system is capable of separating material without mechanical interaction, such as with grippers or end effectors, and relies on air flow through the enclosure to create separation between the desired and undesired material using ballistic coefficient as a fundamental differentiator between constituent material of the agricultural products. This is accomplished with a variable speed fan which blows air through the enclosure, lifting and separating material based on the ballistic coefficient of that material and the flow settings. Dividers are used to separate and capture the products for retrieval at the conclusion of operation.
