    摘要: Non-magnetic, conductive particles are separated from one another on the basis of their respective electrical conductivities. This is achieved by irradiating the particles with microwave or radio frequency electromagnetic radiation and simultaneously subjecting the particles to a magnetic field. The eddy currents induced in the particles by the electromagnetic irradiation interact with the magnetic field to cause movements of the particles which are dependent on their conductivities.

    摘要: A device for separating weakly magnetic first particles, for example hematite particles, from mixture (912) comprising the first particles (913) and less magnetic second particles (914) is presented. The device comprises first magnetizing equipment (901) for producing magnetic field and for moving the mixture so that mutually opposite polarity portions (N, S) of the magnetic field sweep the mixture in a sweeping direction and thereby deflect the direction of movement of the first particles towards the sweeping direction and away from the direction of movement of the second particles. The device comprises also a supply equipment (932) for supplying the mixture to the carrier equipment with the aid of gravitation and a second magnetizing equipment (931) connected to a feed box (920) for producing second magnetic field for deflecting a direction of movement of the first particles differently than a direction of movement of the second particles when the mixture is moved by the gravitation towards the carrier equipment so as to generate, to the mixture arriving at the carrier equipment, a concentration gradient of the first particles. The pre-concentration of the first particles simplifies their separation form the mixture.

    摘要: The present invention provides a soil cleaning method. The soil cleaning method is characterized in that after a pre-treatment step of mixing a dehydrating agent in soil to reduce a water content of the soil to 10 mass% or less is performed, a magnetic separation step of feeding the soil whose water content is reduced to 10 mass% or less in the pre-treatment step, to a dry magnetic separator to separate and remove a contaminant in coarse soil as magnetically attracted matter is performed. By bringing the soil into a dry state to separate the soil into magnetically attracted matter and magnetically unattracted matter and collecting the heavily contaminated magnetically attracted matter, it is possible to facilitate separating fine soil from contaminated soil, which makes it possible to easily reduce the content of the contaminant in the coarse soil.

    摘要: Techniques to rapidly sort different types of cells from a blood sample are of interest in scientific research, the biotechnology industry and medicine. Fluorescence activated cell sorting (F ACS) is now a conventional and standard methodology, but it requires very expensive equipment and is inherently limited by the serial nature of single cell optical sorting. Existing alternative techniques such as centrifugation (using the variation of the density of different cells) and magnetophoresis (using micro/nano magnetic beads to label the cells of interest) have been widely used for the past few decades as parallel sorting techniques. Shortcomings of these common batchwise processes includes the following: they are typically non-continuous.

    摘要: Swarf is removed from drilling mud by outward flour filtration through at least one filter drum rotating about an inclined axis. As shown the mud is fed into the inner drum 52 and flows through perforations 56 therein and then through outer drum 54, which is of finer aperture size. Drums 52, 54 are independently driven at variable speeds in one or opposite directions. A blade between the drums cuts any swarf pieces projecting through perforations 56. The swarf is discharged into container 70 from the lower end of the drums, whose inclination is adjustable. The mud which has been filtered may be fed to a tank from which it overflows as a thin stream down an inclined plate (Fig. 5) where a moving magnetic belt (108) picks up any remaining metal particles.

    摘要: A method of separating a powder mixture is disclosed. A first magnetic field is applied to the powder mixture which contains a non-magnetic metal powder and a contaminant powder. A field strength of the first magnetic field magnetizes the non-magnetic metal powder and leaves the contaminant powder non-magnetized. A second magnetic field is applied to the powder mixture to separate the magnetized metal powder from the non-magnetized contaminant powder.
