Like in
a traditional coating process, in the rotary coating process the
application rate of materials follows a more or less exponential
curve . One main difference is that in traditional pelleting it is
common practice that the operator is constantly and often manually
steering the liquid and powder flow and operator skill is an
important success factor.
In a rotary pelleting process the operators
involvement is limited to
|
controlling the different dosing systems
which may even be further restricted to initiating a pre-determined
programmed process in a highly automated environment.
Specially when a certain process is
very consistent and repeatable, this becomes a true strength of the
rotary technology. High precision and more costly dosing systems
(e.g. gravimetric powder feeders) may be essential to realise the
level of complete automation. |
