The comminution of
materials of bioorganic origin such as organic solids, biological agglomerates
or microorganisms is described in this work. The intend of this disintegration
process is to release products, to improve the product quality or to enhance
biological degradation processes.
Special analytical
techniques based on biochemical parameters are required in order to
characterise the result of the comminution of organic materials. These
techniques supplement techniques that are known from the comminution of brittle
inorganic materials.
The defined stressing of
single particles can be used to characterise the comminution properties of
solid bioorganic materials.
The disintegration of
microorganisms has been investigated in the fields of biotechnological product
release and biodegradability of wastewater sludges. It is possible to optimize
the operational parameters of stirred ball mills based on stress intensity and
stress number in order to reduce the energy input and to improve the product
release.
