CHME461 – Powder Technology

Course description

Overview of industrial applications of powder processing. Characterization of powders: size distribution, shape, flowability. Unit operations for processing particulate materials: size enlargement and size reduction, solid-liquid and solid-gas separation, mixing, storage, pneumatic conveying, fluidization. Nanoparticle technology: production, properties and behaviour. Fire and explosion hazards of powders, industrial dust control and health risks.

Course Pre-Requisites: None

Course Learning Outcomes

  1. Characterize quantitatively the size distribution, shape and flowability of powders.
  2. Identify the basic mechanisms and equipment for unit operations in processing of particulate materials.
  3. Design the production process of high value particles using knowledge of powder technology.
  4. Assess fire, explosion and health hazards of powders.

Course Outline

In this course students will learn about: powders size distribution and shape characterization; powder flowability and its friction properties; unit operations with powders, including milling, agglomeration, mixing, compaction, drying, and flow. The production and the properties of nanoparticles will be introduced, as well as the design powder processess, and the analysis of fire and hazards of poweders in industry, including dust control.
