A device for separating particles contained in a gas stream for selective additive manufacturing and a selective additive manufacturing apparatus are disclosed. The device comprises at least one dry-type aeraulic separator comprising a separating turbine, a speed of rotation of which is variable. The dry-type aeraulic separator selects the particles contained in the gas stream according to a particle size depending on the speed of rotation of the separating turbine. The device also comprises a device for extracting the particles. The dry-type aeraulic separator and the extraction device are in fluidic communication such that a gas stream exiting the dry-type aeraulic separator circulates through the extraction device and such that the gas stream exiting the extraction device circulates through the dry-type aeraulic separator. The device also comprises a device for circulating the gas stream between the dry-type aeraulic separator and the extraction device.

A head assembly having ancillary fan assemblies can be operationally mounted to the outlet of a conventional harvester extractor. The ancillary fan assemblies can generally direct suspended trash materials in a substantially upward and laterally outboard direction toward both lateral sides of a harvester. A duct assembly having an inlet and an outlet generally extends from each ancillary fan assembly to a position generally above a track of a harvester. Trash material expelled by a harvester extractor enters the head assembly and is directed by the ancillary fan assemblies into each of the duct assemblies, through said duct assemblies, and onto the upper surfaces of the tracks of the harvester. The trash material is then conveyed by the tracks toward the front or forward portion of the harvester, where it falls off of the tracks generally in the path of the harvester. As the harvester continues moving forward, the harvester runs over the deposited organic trash material, plowing the organic trash material into the underlying terrain.

A method of increasing volume ratio of magnetic particles in a MnBi alloy includes operating a jet miller fed with a MnBi alloy powder containing magnetic particles and non-magnetic particles with gas flow parameters selected such that, only for the magnetic particles, a gas drag force is greater than a centrifugal force within the jet miller to separate the magnetic particles from the non-magnetic particles.

A head assembly can be operationally mounted to the outlet of a conventional harvester extractor, such as a sugarcane harvester. The ancillary fan assemblies can generally direct suspended trash materials (that would otherwise be expelled from an extractor outlet) in a substantially upward and laterally outboard directionthat is, toward both lateral sides of a harvester. A duct assembly having an inlet and an outlet generally extends from each ancillary fan assembly to a position generally above a track of a harvester. Trash material expelled by a harvester extractor enters the head assembly and is directed by the ancillary fan assemblies into the duct assemblies, through the duct assemblies, and onto the upper surfaces of the tracks of the harvesters. The trash material is then conveyed by the tracks toward the front or forward portion of the harvester, where it falls off of the tracks generally in the path of the harvester. As the harvester continues moving forward, the harvester runs over the deposited organic trash material, plowing the organic trash material into the underlying terrain.
