A method for producing a powdered starting material, which is provided for production of rare earth magnets, including the following steps: pulverizing an alloy, including at least one rare earth metal, wherein a powdered intermediate product is formed from the alloy including at least one rare earth metal, and carrying out at least one classification aimed at particle size and/or density for the powdered intermediate product, wherein a fraction of the powdered intermediate product, which is formed by means of the at least one classification, for fabrication of rare earth magnets. Furthermore, at least one dynamic classifier is provided, implementing at least one classification directed at particle size and/or density for the powdered intermediate product and thereby separates the fraction from the powdered intermediate product, which forms the starting material provided for manufacturing rare earth magnets.

In order to provide an airflow sorting device having high accuracy and easy adjustment properties with a simple configuration, there are provided a conduit which has a central shaft line and which lets an object to be sorted to fall due to gravity on the inside of the conduit along the central shaft line; an air supply port which is provided at a lower part of the conduit and configured to blow air upward along the central shaft line; a suction port which is provided above the air supply port of the conduit and is an opening oriented downward of a suction pipe provided parallel to the central shaft line; and an input port provided above the suction port of the conduit through which the object to be sorted is input into the periphery of the suction pipe which is in the conduit. Sorting is performed in the sorting device according to whether or not the object to be sorted is being suctioned by the suction port together with a part or the entirety of an airflow generated in the conduit by the air blown from the air supply port, and an airflow adjusting body which is provided below the suction port in the conduit and blocks a falling path of the object to be sorted which falls due to gravity, is provided, and the airflow adjusting body includes: a vertex on the central shaft line; and an inclined surface having a sectional shape, sectional areas of which are similar to each other and increase in size downward, and a drag force which acts on the object to be sorted which falls due to gravity increases downward from the suction port.

A hydrocyclone for separating a vapor from a carrier gas is disclosed. The hydrocyclone comprises one or more nozzles. A cryogenic liquid is injected to a tangential feed inlet at a velocity that induces a tangential flow and a cyclone vortex in the hydrocyclone. The carrier gas is injected into the cryogenic liquid, causing the vapor to dissolve, condense, desublimate, or a combination thereof, forming a vapor-depleted carrier gas and a vapor-enriched cryogenic liquid. The vapor-depleted carrier gas is drawn through a vortex finder and the vapor-enriched cryogenic liquid is drawn through an apex nozzle outlet. In this manner, the vapor is removed from the carrier gas.

A cyclone main body includes a cylinder-shaped upper barrel and an inverse cone-shaped lower barrel; a top plate which covers a top edge of the upper barrel and includes an opening at a center portion; a first introduction pipe which introduces a first fluid containing powder along an inner wall surface of the cyclone main body; a second introduction pipe which is disposed near the top plate in a portion upper than the first introduction pipe and introduces a second fluid; an exhaust pipe which is inserted in the opening of the top plate along a vertical center axis of the cyclone main body, makes an exhaust flow rise from the cyclone main body, and discharges the exhaust flow from the cyclone main body; and a collecting section which collects powder separated by turning movement of each of the first fluid and the second fluid in the cyclone main body.

A surface cleaning apparatus comprises a cyclone bin assembly having a sidewall surrounding a contiguous interior volume and comprising multiple segments if different profile and width.
