An analysis of the axial-disk VOlldS characteriatice on condition that the magnetic aystem is optimal has been performed. Phe aim of the present work is to find the optimal geosetrg of the axial-disk volume-gradient magnetic separators (VGHS) , prooeeding from the given design charaoteristios, and to calculate the operating efficiency of these VGBdS, as well as to estimate their power of separa...

At present, wet spraying is the main process for treatment of exhaust gas emitted by concentrated sulfuric acid roasting method decomposition rare earth concentrates, which not only consumes a large amount resources but also wastes residual heat corresponding to temperatures approximately 300 °C. In this paper, an dry processing technology that completely different from original spray proposed ...

Distortion and deformation of tubes during machining operations are very important. In this study, a tube used in magnetic drum separator under concentrated load (machining load) is considered. Using finite element simulation, deformities and their dependence on parameters such as the thickness of the tube and the place of concentrated force are observed and predicted. To compare and confirm th...

To enhance dry magnetic separation of fine-grained materials, our research team developed the pneumatic drum separator (PDMS), an airflow-aided separator. Different positions at surface PDMS have varied angles, so particles different may be subjected to varying composite forces, resulting in a mismatch between airflow velocity and field intensity. However, because process is continuous certain ...

The beam dump is a critical component for the in-flight fragment separator using high-power primary beams at the rare isotope science project (RISP) in Korea. The maximum beam power is planned to be 400 kW, and a third of the primary beam power deposits at the isotope production target and the rest are dissipated at the beam dump. The beam dump is designed to be a rotating water drum, which is ...

A model to account for observed solar flare statistics in terms of a superposition of independent random flaring elements (assumed to be sites of magnetic reconnection in the coronal magnetic field and hence termed ‘‘ separators ’’) is described. A separator of length l is assumed to flare as a Poisson process in time, with a rate ðlÞ inversely proportional to the Alfvén transit time for the st...
