WEAR RATE PREDICTION OF GRINDING MEDIA USING BPNN AND MLR MODELS IN GRINDING OF SULPHIDE ORES
Nowadays steel balls wear is a major problem in mineral processing industries and forms a significant part of the grinding cost. Different factors are effective on balls wear. It is needed to find models which are capable to estimate wear rate from these factors. In this paper a back propagation neural network (BPNN) and multiple linear regression (MLR) method have been used to predict wear rat...
متن کاملAn investigation of the corrosive wear of steel balls in grinding of sulphide ores
Ball mills are common grinding equipment in mineral processing industries. Ball wear results from three mechanisms namely impact, abrasion and corrosion. Of these, the corrosion mechanism is the least investigated, due to its chemical-electrochemical nature. Therefore, the aims of this research were to investigate the grinding chemistry influence (slurry pH, solid percentage, water chemistry an...
متن کاملInduction of Localized Hyperthermia by Millisecond Laser Pulses in the Presence of Gold-Gold Sulphide Nanoparticles in a Phantom
Introduction Application of near-infrared absorbing nanostructures can induce hyperthermia, in addition to providing more efficient photothermal effects. Gold-gold sulfide (GGS) is considered as one of these nanostructures. This study was performed on a tissue-equivalent optical-thermal phantom to determine the temperature profile in the presence and absence of GGS and millisecond pulses of a ...

متن کاملGold-sulphide versus sulphide centres on (111)AgBr surfaces: characterization and mechanism
Octahedral core–shell AgBr emulsions sensitized by sulphur-plus-gold with gold added at 40uC either before or after sulphur sensitization were prepared and studied. The core emulsion was sensitized with a low level of dimethylamineborane (DMAB), and it enhanced the intrinsic sensitivity and long-wavelength sensitivity of the emulsion with an unsensitized shell. Oversensitization was observed fo...
