A particulate collector includes a housing having an air intake port and an exhaust port and a flow channel, in the housing, connecting the two ports, a fan rotatable about an R-axis to generate airflow in the flow channel, a spray unit that sprays first liquid into a first portion in the flow channel, a first filter located between the first portion and the exhaust port and supported rotatably about the R-axis, a power source that rotates the first filter, a first collection port for collecting a first particulate covered with liquid contained in the first liquid from the flow channel through a second portion in the first filter, and a second collection port for collecting a second particulate covered with liquid contained in the first liquid from the flow channel through a third portion in the first filter. The second portion is located between the first and third portions.

This powder-classifying apparatus has: a centrifugation chamber configured so as to be sandwiched between two opposing members; an air supply unit that supplies air into the centrifugation chamber and generates a swirl flow; a raw material supply unit that supplies raw-material powder into the swirl flow; a fine powder recovery unit having an opening part through which air that includes fine powder classified within the centrifugation chamber is ejected to outside of the centrifugation chamber; a coarse powder recovery unit provided to the outer edge part of the centrifugation chamber, for ejecting classified coarse powder to outside of the centrifugation chamber; and an annular slit provided to at least one of the members that constitute the centrifugation chamber, the slit being provided in a region between the center part of the centrifugation chamber and the outer edge part.

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.

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.
