A classifying and purifying apparatus of a solid blowing agent includes a classifier which classifies a supplied solid blowing agent into first microspheres and second microspheres, a storage connected to the classifier, in which the classified first microspheres flow in to be stored and emitted, and a filter arranged on the moving route of the solid blowing agent or the first microspheres which separates metallic substance from the object of filtering comprising the solid blowing agent or the first microspheres.

Disclosed herein is an insect sorting system that includes a conveyor stage having a drive unit, a grasping surface movably coupled with the drive unit and having textured surface elements, and a diverter that is configured to remove insects from the grasping surface.

Insect sorting conveyor systems include at least first and second insect conveyor stages. The first and second insect sorting conveyor stages each include an outwardly facing grasping surface forming at least part of a continuous loop having an upper section and a lower section, and an insect diverter positioned adjacent to the lower section. The second insect sorting conveyor stage is disposed below the first insect sorting conveyor stage.

Provided is a feather separation system for separating feathers from a product in which feathers are filled into a bag-shaped product of a covering. The feather separation system includes: a cutting part configured to cut the product into individual pieces so that at least a part of the bag-shaped product of the covering is open; a feather separation part configured to separate the individual pieces of the product into the feathers and the covering; and an airflow introduction part configured to introduce airflow to the feather separation part.

A specific gravity-specific waste air sorter separates impurities using a vortex for sorting waste into high-specific gravity materials, low-specific gravity materials, and impurities when the impurities are shaken off and removed by means of the hitting of a rotating drum and vanes while the waste fed therein is turned over by a vortex. A main drum has radial vanes, an upper auxiliary drum, and a lower auxiliary drum. The main drum is provided at one side of an input hole, the upper auxiliary drum is provided at the other side of the input hole, and the lower auxiliary drum is provided below the upper auxiliary drum. The main drum and the lower auxiliary drum rotate in the same direction, whereas the upper auxiliary drum rotates in the opposite direction. A vortex is formed between the main drum, the upper auxiliary drum, and the lower auxiliary drum.

A method for separating a particulate stream of an evaporite mineral feedstock, the method comprising passing the stream to an air classifier configured to separate the particulate stream into a fine component and a coarse component.

The present invention is an apparatus and method of using the apparatus for separating individual particles from a collection of clumps (or bundles or aggregates) of particles. The apparatus has n number of separation columns, wherein each separation column is connected at an upper portion thereof to at least one fluid connection, and a particle collector. A pressurized fluid flows through the apparatus and 1) suspends a portion of the clumps within the separation column and/or the at least one fluid connection thereby separating at least some clumps into smaller clumps and/or individual particles; and 2) conveys a portion of the clumps and/or individual particles to the next separation column in the series of separation columns, or, in the case of the nth separation column conveys individual particles to the particle collector.
