Introduction
The cement manufacturing process and all related
transport and logistic systems are driven by strict
requirements regarding the accurate proportioning of
bulk materials from various sources. The corresponding
integration of adequate parts of equipment requires
the systematic selection of dosing and/or metering
devices or scales and the subsequent consideration of
the necessary weighing technologies. If the complete
chain from the quarry and subsequent handling of raw
materials to the dispatch of the final product in bags
or as bulk cement is analysed, it is obvious that the
applied dosing equipment needs to be able to handle
a great variety of different types of bulk materials in
terms of their general appearance (powdery, granular,
flaky, fibrous etc.), their followability (free-flowing,
cohesive, etc.), their granularity (size of smallest and
biggest 2D or 3D particles) and their general bulk
material properties (e.g. density, humidity, etc.).
Within this context, it is also important to consider
the long-term stability of the aforementioned
characteristics, which is often underestimated
during the design phase of bulk material handling
systems, especially if there is a lack of experience
with the utilisation of novel materials, e.g. during the
introduction phase of new alternative or secondary
fuels. Therefore, it is essential to start the systematic
selection of adequate dosing equipment with a
holistic approach towards the exact characterisation
of the bulk material by means of mechanical, chemical
and other relevant evaluation methods. It is also
noteworthy, that the actual process requirements
