Die Erfindung betrifft eine Sortiereinrichtung (2) für Tabletten (1) zum Aussortieren von Mehrfachtabletten (1'). Die Sortiereinrichtung (2) weist mehrere Stationen umfassend eine Zuführstation (3), eine Sortierstation (4) sowie eine Auswurfstation (5), und einen in einer Umlaufrichtung (8) die einzelnen Stationen anfahrenden Tablettentransporter (7) auf. Der Tablettentransporter (7) umfasst mindestens eine Reihe von Tablettenaufhahmen (9) für einzelne Tabletten (1) sowie mindestens eine seitlich neben den Tablettenaufhahmen (9) positionierte Dublettenaufnahme (10) für aussortierte Mehrfachtabletten (1'). Eine einzelne Tablettenaufnahme (9) ist mittels einer Seitenwand (11) seitlich von der Dublettenaufnahme (10) abgetrennt. In der Sortierstation (4) ist mindestens ein Sortierzinken (12) vorgesehen, welcher in einer quer zur Umlaufrichtung (8) verlaufenden Seitenrichtung (13) über einen Verfahrweg (14) derart hin und her verfahrbar ist, dass der Sortierzinken (12) dabei den Bereich einer Tablettenaufnahme (9), der benachbarten Dublettenaufnahme (10) und der zwischenliegenden Seitenwand (11) überstreicht.
摘要:
A method for processing polycrystalline silicon workpieces to form size distributions of polycrystalline silicon pieces suitable for use in a Czochralski-type process includes: (1) preparing a polycrystalline silicon workpiece by a chemical vapor deposition process; (2) fracturing the polycrystalline silicon workpiece into a mixture of polycrystalline silicon pieces, where the polycrystalline silicon pieces have varying sizes; and (3) sorting the mixture of polycrystalline silicon pieces into at least two size distributions. Step (2) may be carried out by a thermal shock process. Step (3) may be carried out using a rotary indent classifier. A rotary indent classifier for performing the method includes: (i) a rotating cylinder having a circumferential edge with indents arrayed in increasing size from a first end of the cylinder to a second end of the cylinder, and (ii) a conveyor running longitudinally adjacent the cylinder, for conveying silicon pieces from the first end of the cylinder to the second end of the cylinder.

A mixture of same diameter, cylindrical catalyst particles are length graded into a first group having a a length L1 and a value of L/D greater than one, and a second group having a length greater than L1, by: feeding the mixture into a cylindrical drum (100) having inwardly opening indentations (104) in a cylindrical wall (102) the indentions having a transverse diameter of substantially L1; rotating the drum to entrap in the indentations and convey the particles having a length below L1 upwardly to a height permitting the particles to fall into a fixed, upwardly opening trough (106), while retaining particles having a length above L1 in the bottom of the drum. In addition a spent catalyst particle mixture comprising relatively uncontaminated particles and heavily contaminated particles is density graded.

A grain cleaner is taught including features for facilitating maintenance and repair of the cleaner over previous grain cleaners. In particular, the grain cleaner has an indent cylinder assembly which includes a removable cylinder. The cylinder is removed by unwrapping it from around a frame. The grain cleaner also includes at least some augers with drop away troughs. The grain cleaner also includes grain cleaning assemblies such as, for example, indent cylinders and rotary screen drums and/or grain cleaning assemblies drive systems which are mounted on framework members capable of pivoting outwardly from the machine allowing access to machinery and components positioned centrally within the grain cleaner.
摘要:
A method and an apparatus for the sorting of chips (3). The chips, which have kinetic energy, are separated from each other on the basis of the form or the length of their flight curve which depends on their air resistance. The kinetic energy of the chips is generated by a mechanical ejecting device (6) ejecting the chips or by means of a fan conveyor or by means of the wings of a blowing chipper.
摘要:
Es wird eine Vorrichtung zum Separieren fließfähiger Schüttgüter, insbesondere Getreide, beschrieben, die aus wenigstens einem Rundkorntrieurzylinder (10), einem Langkorntrieurzylinder (11) sowie einer dem Rundkorn- und dem Langkorntrieurzylinder bezüglich der Schüttgutstromrichtung vorgeschalteten Vorsortiervorrichtung besteht. Die Vorrichtung soll bei einem möglichst großen Massendurchsatz an Schüttgut ein möglichst geringes Bauvolumen aufweisen sowie eine höhere Reinigungs- und Sortiergenauigkeit ermöglichen. Diese Aufgabe wird dadurch gelöst, daß als Vorsortiervorrichtung ein Scheibentrieur (12) vorgesehen wird.
摘要:
An arrangement in a winnower comprising at least one rotational member (10) e.g. a disk or a cylinder, having cells for lifting seeds and other particles from a lower position to a higher position and a chute (14) for receiving the lifted material. The rotatable member is associated with at least one sensor (17) located in the flow of the lifted material supplied to the chute, for generating electric signals in dependence on impingement of material particles leaving the rotatable member and falling down into the chute. The sensor is operatively connected through a function circuit (18) to adjusting means for controlling an operational parameter of the winnower in dependence on the impingement intensity.
