摘要： The invention relates to a method of separating a particle fraction from a particle stream making use of gravitational force and which is performed in a fluid. This provides particle fractions that are collected in respective collecting means. According to the invention the fluid and the collecting means are moved in relation to each other defining a relative direction of movement. There are means provided to limit the movement of the particles to be separated with respect to the fluid in the relative direction of movement. The invention also relates to an apparatus for carrying out the method.

摘要： The invention concerns a grader operating on the air separation principle and comprising: a housing (1); a rotor (2) mounted in the housing so as to rotate and comprising two rotor discs (5, 6) and blades (4) between the discs; and an outer channel (7) formed by the circumference of the rotor (2) and the housing (1) for feeding in solids and the fluid. In order to minimise turbulence detrimental to grading, it is proposed that the diameter of the rotor discs (5, 6) should be chosen to ensure that the outer edges of the rotor discs should protrude into the solids and fluid feed channel (7) and form the lateral boundaries thereof.

摘要： 1. Verfahren und Vorrichtung zur Trennung eines feinkörnigen Feststoffes in ein Feingut und ein Grobgut bei einer Trennkorngröße unterhalb 50 µm, vorzugsweise unterhalb etwa 10 µm. 2.1 Aufgabe der Erfindung ist es, ein Verfahren und eine Vorrichtung anzugeben, die in wirtschaftlicher Weise eine scharfe Trennung vor allem im Kornbereich unterhalb von etwa 10 µm ermöglichen. 2.2 Zur Lösung dieser Aufgabe wird der feinkörnige Feststoff in einer tropfbaren Flüssigkeit dispergiert und die Dispersion in eine definierte Senkenströmung mit überlagerter, unabhängig von der Senkenströmung erzeugter Rotationsströmung gezwungen. Das Verhältnis der Geschwindigkeiten von Senken- und Rotationsströmung bestimmt die Trennkorngröße. 2.3 Als Vorrichtung dient ein rotierend angetriebenes, von außen nach innen durchströmtes Abweiserad (3) mit parallel zu seiner Drehachse verlaufenden und Strömungskanäle bildenden Schaufeln (17), dem die Feststoffdispersion am Außenumfang aufgegeben wird.

摘要： A method of reblending sand in a classification tank (10) having multiple stations (14A-J) and discharge valves (16A-C) within each station includes the steps of delivering sand to the tank (10); calibrating the tank to analyze the raw feed material and develop discharge rates, flow multipliers, and a mathematical model of the tank; and inputting a specification or quantity and sieve size distribution for a reblended sand product into a computer (20) for controlling the tank (10). Then the tank (10) is operated in a production mode and the discharge valves (16A-C) at each station of the tank (10) are adjusted by the computer (20) for percent open time and discharge rate. With one algorithm, the computer (20) identifies which station (14A-J) has the most of a sieve size that is out of specification and diverts material at that station by closing the appropriate discharge valve(s) (16A-C). In another algorithm especially adapted to minimize fines, the computer (20) begins with the station (14A-J) most remote from the inlet and diverts material by repeatedly reducing the valve (16A-C) open percentage of the appropriate valve (16A-C) at that station (14A-J) by a given amount until the specification is met or the valve (16A-C) is always closed. Once the valve (16A-C) is always closed, the computer (20) moves a station (14A-J) closer to the inlet and repeats the process. Once a primary product is being produced to specification, the same algorithm can be used to control the production of a secondary product.
