Macroscopic particle processes from an industrial perspective:
Production, handling, storage, transport
and processing of particles and granular
materials is of paramount importance in
all sectors of industry.
40% of the capacity of industrial plants is
wasted due to granular solid problems (**)
Between 1 and 10% of all the energy is
used in comminution, i.e. the processes
of crushing, grinding, milling, micronising (*)

Macroscopic particle processes from an industrial perspective:
More than 50% of all products sold are
either granular in form or involve
granular materials in their production*.
40% of the value added in chemical
industry is linked to particle technology**.
Many industrial solid particle systems
display unpredictable behaviour, leading
to losses of resources, energy, money, time
State-of-the-art simulation tools show
lack of predictive capability
