Abstract:
A machine (1) and a method for the treatment of hazardous medical waste; the waste is fed in a treatment chamber (4) defined inside a cylindrical containing body (3) which is mounted so as to rotate around a rotation axis (5); the waste is shred by means of a shredding device (9) which is arranged inside the treatment chamber (4); at the end of shredding the vacuum is generated and maintained inside the treatment chamber (4) for a first time interval (T1 ); at the end of the first time interval (T1 ) the vacuum generation is interrupted and vapour under pressure is fed into the treatment chamber (4) for a second time interval (T2); and at the end of the second time interval (T2) the vapour feeding is interrupted and the vacuum is generated and maintained again inside the treatment chamber (4) for a third time interval (T3).
Abstract:
Compositions in accordance with the invention comprise a polymer and flake reinforcing material distributed throughout the polymer in an effective amount to structurally reinforce the polymer. Individual flakes of the flake material (a) are less than or equal to 1,000 Angstroms in thickness, (b) have an aspect ratio greater than or equal to 100, and (c) are preferably significantly randomly oriented throughout the polymer. A novel apparatus for shear grinding a platy solid material into such individual flakes comprises a cylindrical shearing drum and a shear grinder received therein. The shearing drum has a longitudinal axis and an internal surface formed about a first predetermined radius of curvature. The cylindrical drum is supported for rotation about its longitudinal axis. The shear grinder has an external surface formed about a second predetermined radius of curvature. The second radius of curvature is slightly less than the first radius of curvature.
Abstract:
Disclosed is a nano grinding mill including a lower turntable with a disc plate mounted on the lower portion thereof, and upper and intermediate plates disposed above the lower turntable, each of the upper and intermediate plates having several tens to several thousands of pressure grinding rods mounted thereon, the upper plate being adapted to fix the pressure grinding rods and the intermediate plate being adapted to eccentrically rotate the pressure grinding rods.

본 발명은 식품원료 분쇄기에 관한 것으로, 본 발명에 따른 식품원료 분쇄기는, 식품원료가 투입되는 공급구 및 미분쇄된 식품원료가 배출되는 배출구를 포함하는 하우징; 중심부, 상기 중심부로부터 방사상 외측 방향으로 서로 이격되게 연장형성되는 것으로 복수 개의 날개부를 포함하고 상기 하우징 내에 설치되는 한 쌍의 임펠러; 및 상기 한 쌍의 임펠러를 각각 구동시키는 한 쌍의 구동체;를 포함하되, 상기 날개부에는 오목한 홈이 형성된 와류면이 형성되고, 상기 한 쌍의 임펠러는 각각에 형성된 상기 와류면이 마주보도록 설치되며, 본 발명에 따른 식품원료 분쇄기를 사용함으로써, 분쇄과정 중 식품원료 간의 충돌 및 식품원료와 공기와의 충돌에 의해 식품원료를 분쇄시킴으로써, 미분쇄된 식품원료에 이물질이 혼합되는 것을 방지할 수 있고, 건식 및 습식의 식품원료에도 적용될 뿐만 아니라 분쇄과정이 분쇄기에 의한 직접 분쇄가 아닌, 분쇄기의 구동에 의해 간접 분쇄되기 때문에 식품원료의 품질을 유지할 수 있고, 임펠러의 형상에 의해 임펠러의 회전속도에 비해 풍속이 높아지는 구간을 형성함으로써, 식품원료를 균일한 입자로 미분쇄할 수 있다. 또한, 식품원료 분쇄기가 구동되어도 저온상태를 유지할 수 있기 때문에 식품원료가 온도에 의해 변질되는 것을 방지할 수 있다.
Abstract:
A method and apparatus processing materials including municipal waste at ambient pressure and low temperatures, and processing materials; the apparatus comprising an elongated rotating cylindrical configuration.
Abstract:
Comminution apparatus is described which is tailored for the processing of green, soft, and fibrous waste. Inner and outer comminution drums bear projecting macerating features which can progressively interact to provide a shearing action on material on waste within the outer comminution drum. Screening apertures on the outer comminution drum allow for the exit of comminuted material.
Abstract:
Eine Vorrichtung (101; 101a; 101b) zum Bearbeiten von Dispersionen weist mindestens ein gegenüber einer Streichfläche einer Scherplatte (1; 1a, 1') zu einer scherenden Bewegung geführtes und über eine Antriebswelle (111) zu einer Drehbewegung (16) angetriebenes längliches Scherwerkzeug (3) auf. Das jeweilige Scherwerkzeug (3) erstreckt sich unter einem Winkel (z.B. -α,+α) quer zur Achse (111a) der Antriebswelle (111). Dabei besitzt das jeweilige Scherwerkzeug (3) eine im Wesentlichen quer zur Achse (111a) der Antriebswelle (111) verlaufende Scherkante (3d) an einer Scherfläche (3c). Ferner ist das jeweilige Scherwerkzeug (3) mit der Antriebswelle (111) einseitig über ein Kardangelenk (10a) verbunden. Eine Belastungseinrichtung (6), insbesondere eine Feder belastet die Scherkante (3d) etwa in ihrem Bereiche oder nahe diesem gegen die Scherplatte (1; 1a; 1') hin, während die Scherfläche (3c) auf Grund des Kardangelenkes (10a) einerseits und der Belastungseinrichtung (6a) anderseits, einen Einzugswinkel (4) bildend, schräg zur Scherplatte (1; 1a; 1') verläuft.
