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...

In thepresentwork,we investigate the destruction efficiency of hexachlorobenzene (HCB) by milling with various reagents in a planetary ball mill under different milling conditions. Under the same conditions of mill rotary rate and charge ratio, the mixture of magnesium powder and aluminum oxide (Mg/Al2O3) was found best in promoting the destruction of HCB, which can be completed destroyed after...

Tumbling mill of thermal power plant, grinding the raw coal for the boiler, has high energy consumption, and pulverizing capability is usually used for representing the efficiency of tumbling mill. In the paper, a variable selection method for pulverizing capability prediction of tumbling mill based on improved hybrid genetic algorithm is proposed. Based on the tradition GA, the proposed method...

Clarithromycin (CLA), a broad-spectrum macrolide, is a poorly soluble drug with dissolution rate limited absorption. The aim of this investigation was to prepare CLA nanoparticles from a ternary ground mixture in the presence of sodium lauryl sulfate (SLS) and polyvinyl pyrrolidone (PVP) as co-grinding water-soluble compounds, in order to improve the drug dissolution rate. Different weight rati...

Copper slag is a hard material produced from smelting copper-bearing ores. Over the years, research has prioritized utilizing as secondary source of base metals. This paper focuses on grinding/milling copper collected BCL Mine in Botswana to obtain maximum amount desired size class with minimal energy consumption. will then be followed by an integrated flotation and leaching approach recover co...

In this study, the relationships between liberation degree and kinetic breakage parameters of a chromite ore obtained from Burdur (Türkiye) were examined under laboratory conditions. Firstly, degrees for particles determined by particle counting method in metal microscope 4 different size groups. Secondly, parameter which was dry ground with ball mill using standard test methods. Additionally, ...
