In a method for separating rich ore particles from agglomerates which contain said rich ore particles and magnetizable particles attached thereto, especially Fe3O4, in the course of a process for obtaining rich ore from crude ore, in which agglomerates the rich ore particle and the magnetizable particle are bonded by organic molecular chains, the agglomerates are contained in a suspension containing a carrier fluid and are broken up by an input of mechanical energy so that an agent contained in the suspension and decomposing the exposed, hydrophobic molecular chains can act upon the molecular chains. The Fe-containing oxide components are separated from the suspension in a magnetic separation process.

摘要:
A travelling field reactor and a method for separating magnetizable particles from a liquid using said travelling field reactor are disclosed. The travelling field reactor may include a tubular reactor, the outer circumference of which is provided with at least one magnet for producing a travelling field and through the interior of which the liquid flows. A displacement element may be located in the interior of the tubular reactor, said element admitting a liquid into the interior of the tubular reactor, which mixes with the liquid flowing in the reactor.
摘要:
A method and a device for determining the flow rate of magnetic or ferromagnetic particles in a suspension that flows through control chambers are provided. The magnetic flux F1 is measured as a function of time t using a measuring coil that surrounds a first control chamber, the magnetic flux representing a measurement, at a particular time, of the quantity of magnetic particles contained in the suspension. In a second control chamber, at a predetermined distance d from the first control chamber, the magnetic flux F2 is measured as a function of time t using a second measuring coil that surrounds the second control chamber and the measurements F1 (t) and F2 (t) are compared to produce a temporal distance Δt which is used together with the predetermined distance d to calculate the flow rate. The method and device can be used, for example, in an ore mining installation.

An assembly for separating magnetisable particles from a liquid may include a tubular reactor through which the liquid can flow and which includes a first region with at least one permanent magnet and a second region with at least one electromagnet. The first and the second region are arranged one behind the other along a longitudinal axis of the tubular reactor.
摘要:
A ship propulsion system for watercraft contains at least one propeller, by which a drive force can be created for the watercraft. The ship propulsion further contains an electric motor, the rotor of which is directly mechanically coupled to the at least one propeller via a shaft such that the at least one propeller may be brought into a respective rotating movement by a rotation of the rotor. In order to cool the rotor of the electric motor a thermosiphon is disposed in the shaft, and the propeller serves as a heat sink for a working medium of the thermosiphon.
