SE 385. Science and Technology of Particulate Materials (3 - 0 - 0 - 0 - 4)
Course Outline:
Particle characterization - particle size distribution in single and multiple particle attributes; measurement principles and techniques involving size, density, pore structure, morphology and specific surface area. [8]
Surface charge of particle and charge modification. [2]
Theory of particle fracture and stress distributions. [2]
Particle in fluids-theory of forces on particle and setting phenomenon. [4]
Population balance concept: classifying particulate processes by birth, death and continuous growth rates. [6]
Particle mechanics - inter -particle forces and their effects at contacts; bed friction; yield criteria for packing, adhesion. Modeling particulate assembly with the Discrete Element Method. [4]
Bulk properties and behaviour: storage and flow of particles in chutes, silos, and bins;
Conveying; dust explosion; flow metering. [4]
Principles of unit operations: crushing and grinding, classification, gravity concentration, heavy medium separation, agglomeration, pelletization and compaction, mixing, extrusion of pastes, magnetic and electrostatic separation, filtration, froth flotation. [10]
Particulate materials of future: nanoparticles, magnetic, electro-rheological fluids. [2]
