Abstract:
A comminutor reduces the size of particles of frangible blast media from each particle's respective initial size to a size smaller than a desired maximum size. The frangible blast media may be entrained in a flow of transport gas. The comminutor includes an inlet and an outlet, both in fluid communication with an internal flow passageway. The internal flow passageway includes a first intermediate passageway which comprise the gap defined by two rotating rollers and a second intermediate passageway which includes an inlet disposed proximal the gap, extending in an upstream direction therefrom.
Abstract:
The present disclosure presents a method and a system for modifying a surface of a substrate. The method includes an act of abrasive blasting of a part of the surface of the substrate. In the abrasive blasting, an abrasive media is provided to the part of the surface. The abrasive media is carried to the part by a first carrier. The abrasive media collides with the part of the surface and causes abrasion to the part of the surface. In the method, the first carrier includes steam. The steam of the first carrier heats the part of the surface.
Abstract:
An apparatus is described which introduces cryogenic particles received from a source of particles, having a first pressure, into a moving transport fluid, having a second pressure, for ultimate delivery to a workpiece or target as particles entrained in a transport fluid flow which seals between the source of particles and the transport fluid flow.
Abstract:
A fragmenter provides fragmentation of frangible blast media entrained in a subsonic flow. The flow is converged prior to reaching a fragmenting element, and the convergence may be followed by a constant cross-section area section. Immediately upstream and downstream of the fragmenting element may be an expansion area to reduce the potential of water ice buildup.
Abstract:
Die Erfindung betrifft ein Verfahren zum Entgraten eines Gummi-Formteiles (2), aufweisend die Schritte: Bereitstellen eines Gummi-Formteiles (2), das einen zu entfernenden Grat (20) aufweist, Kühlen des Grates durch beaufschlagen des Grates mit einem verflüssigtem Gas (4), und Beaufschlagen des Grates mit Trockeneispartikeln zur Entfernung des Grates. Weiterhin betrifft die Erfindung eine entsprechende Einrichtung (1) zum Entgraten von Gummi-Formteilen.
Abstract:
Dry cleaning casing (50) for cleaning by impacting a cleaning member (5) to a cleaning target (20) using an air flow. The dry cleaning casing (50) includes a casing body (52, 52A, 52B) including an internal space (64) for flying the cleaning member; an opening (18) to which the cleaning target (20) can be contacted; and an air introduction route (24) to flow external air to the internal space (64), to generate rotating air flow for flying the cleaning member (5); a flow restriction member (16) defining a rotation axis in the internal space (64), the flow restriction member (16) having an inner space communicated to the internal space (64) and used as a suction route for a suction unit (6); and a screen plate (14) to block movement of the cleaning member (5) to the suction unit (6) and to pass through substance removed from the cleaning target (20).
Abstract:
Cleaning media (PC) having a thin shape and used in a dry-type cleaning device for cleaning a cleaning target by being blown by an air flow and collided with the cleaning target includes a fracture induction part (LY) inducing fracture and being formed so that, upon being fractured along the fracture induction part into pieces, at least one acute-angle part is formed in at least one of the pieces.
