摘要： A method and a plant for the production of a powdery starting material, which is provided for the manufacture of rare earth magnets, are disclosed. First of all, at least one magnetic material, which is comminuted into a powdery intermediate product with a possibly increased concentration of impurities, and/or at least one alloy including rare earth metal are provided, which includes a low concentration of impurities. A classification of the powdery intermediate product to at least one criterion takes place subsequently, wherein, for the classification of the powdery intermediate product with the increased concentration of impurities, at least one dynamic classifier is provided, which divides the powdery intermediate product with impurities into at least two fractions based on the at least one criterion, wherein at least a high concentration of impurities accumulates in a first fraction and no impurities or at least a lower concentration of impurities than in the case of the first fraction accumulate in a second fraction, and wherein the fraction without impurities or with a low concentration of impurities forms the starting material for the manufacture of rare earth magnets.

摘要： A separator for separating solid particles from a processing gas stream that has been fed repeatedly through a work machine, wherein the separator includes a processing gas inlet through which particle-laden processing gas emitted from the work machine is fed into the separator, and a filterless separator element to reduce the particle content of the processing gas and a processing gas outlet to discharge the processing gas with its reduced particle content to the work machine, the separator including a secondary stream filter, which filters a smaller portion of the processing gas, and a secondary outlet, connected thereto, which ejects the filtered secondary stream of processing gas.

摘要： A fastening system for filter bags and baskets. The filter bag with a first outer diameter for filtering dust particles and a filter basket for the internal stabilization and fastening of the filter bag. A connecting region arranged on a perforated filter plate for connecting the filter bag and/or the filter basket to the filter installation. The connecting region includes a cutout for the filter bag. The filter bag includes at one end at least one snap ring for the connection to the connecting region, and has a second outer diameter in the region of the snap ring. The filter basket includes at its upper end at least two spring elements for connection to the connecting region. The snap ring is elastically deformable and can be brought into at least a first shape, the cross-sectional area whereof is smaller than an area of the inner cross-section of the cutout of the perforated filter plate.

摘要： A method for producing a homogenized mixture of carbon, sulfur, and PTFE, wherein the sulfur is liquefied, and the liquid sulfur is then ground for the first time together with the carbon, so that the liquid sulfur is absorbed by the pores of the carbon particles and forms a preferably powdery composite with the carbon particles, whereupon PTFE is added and the mixture of the composite and the PTFE is then ground a second time and is thus homogenized.

摘要： A method and a device for generating superheated steam from a working medium, which includes the following steps: feeding of a working medium in the liquid phase to a specific heating tube and temperature regulation of the specific heating tube. Furthermore, the specific heating tube is temperature-regulated with a defined amount of thermal energy, as a result of which superheated steam is formed in the specific heating tube from the working medium fed in the liquid phase, the superheated steam then departing from the specific heating tube.

摘要： An operating method for a separator for classifying, wherein superheated steam is supplied to the separator as separating gas, and wherein the temperature of the superheated steam as separating gas is selected to be so low that in particular no condensation of the superheated steam occurs in the separator. Further, a separator for classifying, wherein the separator includes a separating gas supply including a water infeed for generating superheated steam as separating gas, and wherein adjusting or regulating means for the temperature of the superheated steam are provided as separating gas and are designed in such a way that the temperature of the superheated steam as separating gas is adjusted to be so low that in particular no condensation of the superheated steam occurs in the separator.
