Design of an induced roller magnetic separator for mineral value addition
No full textMaterial separation is critical in value addition process especially in mining and other related industry. There are several methods employed in separating material into different classes. Magnetic separator as a separation technique/method leverages the magnetic properties of materials and is employed in various industries, including mineral processing industries, recycling, and resource recovery. Researchers and Engineers have conducted numerous studies to comprehend how different types of paramagnetic minerals behave when separated using various separator technologies. However, despite these efforts, these separators have not been widely adopted for processing different paramagnetic minerals because most of the existing induced roller magnetic separator have poor efficiency, cost-effectiveness and adaptability for different paramagnetic minerals. This paper examines the current state of these separators, providing an overview of their operational mechanisms, practical uses, and theoretical models. It goes further to design an induced roller magnetic separator after considering various factors such as magnetic susceptibility, cost, adaptability and performance efficiency, while observing certain industry specifications. The resulting design will be able produce a magnetic field of about 2.2 Tesla that can be used to separate certain minerals for a reasonable period of time. Further implementation and modification of this design will hope to yield an increase in the extraction and processing of various minerals internally within Nigeria, minimizing dependence on importation of machines, providing jobs and improving the economic status of this countr
Temperature-Driven Dynamics of Small Spherical Particle Adhesion on Submerged Substrates: Mechanisms and Interfacial Interactions
No full textUnderstanding the adhesion dynamics of small spherical particles on submerged substrates is crucial for various applications in colloidal science, materials engineering, and industrial processes. This study investigates the force required to initiate the rolling motion of glass spheres on an inclined glass surface in water and ethanol, examining the effect of temperature on this force. The results confirm the presence of van der Waals attractions between the spheres and the substrate, which are weakened by thermal energy. As temperature increased, the liquid matrices expanded, reducing density while decreasing the angle of inclination needed for particle motion. This reduction was attributed to a decrease in the coefficient of friction with rising temperature. The Hamaker coefficient, derived from the experimental data, ranged from 1.986 × 10⁻¹⁵ to 5.296 × 10⁻¹⁵ mJ/m² in water and 2.262 × 10⁻¹⁵ to 5.278 × 10⁻¹⁵ mJ/m² in ethanol, suggest agreement with literature values and showing a tendency to increase with temperature. Similarly, the coefficient of friction decreased from 0.0680 to 0.0400 in water and from 0.0480 to 0.0326 in ethanol, further supports the role of thermal energy in modifying interfacial interactions. These findings provide insights into the thermally driven adhesion mechanisms of submerged particles, with implications for optimizing material handling, coating technologies, and microfluidic system
