Beschreibung
Zusammenfassung:	The invention relates to an equipment and a process for producing magnetizable nano-micro-particles as spheres from metallurgical slag, in plasma jet. According to the invention, the equipment comprises a plasma generator (A), an enclosure (B) which creates thermodynamic conditions and plasma-chemical reactions for the nano-micro-particles to be formed, a wet filter ( C) for collecting nano-micro-particles, a water-gas heat exchanger (D) intended to bring the gas temperature to values lower than the values which would affect a mechanical vacuum pump (E) used to create within the enclosure (B) preset pressures required for the nano-micro-particles to be formed for each class of preset dimensions, a current source (F) which supplies the plasma generator (A), a plasmagen gas storage (G), a powder dispenser (H) connected to a subassembly (I) consisting of a roller and screen mill, as well as a control desk and a software which controls the technological process (Pc). Invenţia se referă la un echipament şi un procedeu de obţinere a nano-microparticulelor magnetizabile sub formă de sfere din crustă metalurgică în jet de plasmă. Echipamentul, conform invenţiei, cuprinde un generator de plasmă (A), o incintă (B) care creează condiţiile termodinamice şi reacţiile plasmo-chimice de formare a nano-microparticulelor, un filtru umed (C) pentru colectarea nano-microparticulelor, un schimbător de căldură apă-gaz (D) cu rolul de a aduce temperatura gazului la valori inferioare celor care ar afecta o pompă mecanică de vid (E), cu ajutorul căreia se creează în incintă (B) presiuni prestabilite, necesare pentru formarea nano-microparticulelor pe clase de dimensiuni prestabilite, o sursă de curent (F) care alimentează generatorul de plasmă (A), o magazie de gaz plasmogen (G), un dozator de pulberi (H) conectat la un subansamblu (I) format dintr-o moară cu valţuri şi site, precum şi un pupitru de comandă şi un soft care comandă procesul tehnologic (Pc).
