Title: Method of preparing a magnetic composite material and suspension for preparing in this way
Inventor: ŠAFAŘÍK IVO
IPC: H01F1/11
Filed: 2019-02-14
Abstract: Magnetic composite materials are usually prepared by modifying a suitable diamagnetic or non-magnetic material. The method of magnetic modification for extremely fast preparation of magnetic composite materials, is based on thoroughly mixing the suspension of magnetic nanoparticles and / or microparticles in highly volatile organic solvents with the selected modified material. Alternatively, the magnetic suspension can be sprayed onto the modified diamagnetic material. Various types of magnetic suspensions can be used, which have a low boiling point of the organic solvent used, for example chloroform, petroleum ether, dichloromethane, acetone or n-pentane or other low-boiling organic compounds. The final magnetically modified product can be obtained in a very short time, usually within 5 to 10 minutes, in contrast to conventional postmagnetization techniques which typically require several hours of drying.

IPC: B01J8/24
Filed: 1996-12-17
Abstract: In the present invention, there is disclosed a method for the continuous treatment of particulate material, such as cement raw meal, in an apparatus comprising at least one stationary reactor (6) configured as a spouted bed, to which the material is fed and treated in a suspended bed by means of gas which, via a centrally arranged gas inlet (21), is injected at the bottom of the reactor (6) and flows upwards through the reactor (6), and wherefrom the material is discharged via the gas inlet (21) under gravity against the gas flow at the bottom of the reactor (6). The invention is characterized in that the dimensions and operating parameters of the reactor (6) and the connected apparatus volumes (8a) are selected and controlled in such a way that during operation the bed is caused to pulsate up and down in the reactor (6) in a controlled manner at such an amplitude that a quantity of the bed material corresponding to the quantity of fresh feed material is, when the bed is situated in its lowermost position, brought into a zone (22) in which the gas flow velocity is lower than the minimum velocity required for suspending the bed particles, whereby that quantity of the bed material drops through the gas flow out of the reactor (6). The apparatus is also provided with means for regulating the pulsation amplitude of the bed in a controlled manner, whereby said regulating means either comprise means for regulating the longitudinal and/or diametrical dimensions of a gas inlet section (21) of the duct or means for regulating the volume (8a) of at least one another apparatus connected to the reactor (6).
