A separation device includes a first ejection unit that ejects a material containing a fiber together with gas and supplies the material onto a first surface of the mesh, a first suction unit that sucks a part of the material supplied onto the first surface, a second ejection unit that ejects gas toward a second surface, and a second suction unit that sucks and collects, the material that does not pass through the mesh by the first suction unit and remains on the first surface. Q1<Q2 and Q3<Q4, where a flow rate of gas ejected from the first ejection unit is Q1, a flow rate of gas sucked by the first suction unit is Q2, a flow rate of gas ejected from the second ejection unit is Q3, and a flow rate of gas sucked by the second suction unit is Q4.

A separation device includes a rotating member that has a mesh having a first surface and a second surface in a front and back relationship and a protruding member provided on the first surface side of the mesh, a supply unit that supplies a material containing a fiber onto the first surface of the mesh, a suction unit that is provided on the second surface side of the mesh and configured to suck a part of the material supplied onto the first surface, and a collection unit that collects the material deposited on the first surface.

This invention relates to a classifier for separating particles by size and density and a method of classifying particles by size and density. The classifier, which is also used in the method, includes an underflow outlet for conveying a first product out of the classifier; a fluidising means for introducing a fluidisation fluid into the classifier; a settling chamber for forming a hindered-settling zone, the settling chamber being in fluid flow communication with the fluidising means and the underflow outlet; a reflux chamber for forming a free-settling zone, the reflux chamber being in fluid flow communication with the settling chamber and having a cross-sectional area larger than that of the settling chamber; a launder in fluid flow communication with the reflux chamber for conveying a second product to an overflow outlet of the classifier; and an inlet conduit which projects into the classifier for introducing a feedstock into the classifier.

A device (1) with which lightweight fractions, such as films or paper for example, being carried along in a carrier airflow (A) are separated and discharged for further processing. The device is characterized in that the housing can be easily opened by means of two pivotal cover hoods (3, 4) in order to allow maintenance work to then be carried out safely. The first cover hood (3) has an intermediate piece (31, 31′) which extends into the housing and has chamfered surfaces (30, 30′) at the ends, wherein the surfaces assuming a known specified angle α relative to the vertical, wherein the inner chamfer docks precisely against the chamfer of a guide element (27).

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.
