Particle technology is a term used to refer to the science and technology related to
the handling and processing of particles and powders. Particle technology is also
often described as powder technology, particle science and powder science.
Powders and particles are commonly referred to as bulk solids, particulate solids
and granular solids. Today particle technology includes the study of liquid
drops, emulsions and bubbles as well as solid particles. In this book only solid
particles are covered and the terms particles, powder and particulate solids will
be used interchangeably.
The discipline of particle technology now includes topics as diverse as the
formation of aerosols and the design of bucket elevators, crystallization and
pneumatics transport, slurry filtration and silo design. A knowledge of particle
technology may be used in the oil industry to design the catalytic cracking reactor
which produces gasoline from oil or it may be used in forensic science to link the
accused with the scene of crime. Ignorance of particle technology may result in
lost production, poor product quality, risk to health, dust explosion or storage
silo collapse.
