TECHNOLOGY
In the not-too-distant future,
digitalisation tools are expected to
be integrated at all mining stages
from exploration, engineering and
simulation to advance process control.
The plug-and-play
system is supplied
fully tested and
pre-configured.
Using webserver
functionality, the
process engineer
can easily and
quickly adapt
or optimise all
parameters
without any

Siemens adds plug-and-play controller for optimised load distribution to the Simine
portfolio for high-pressure grinding mills.
KHD Humboldt Wedag International AG commissioned and optimised the controller
self-dependent within the first weeks after production start-up. That put KHD in the
position to utilise all benefits of the controller and without any support from a service
engineer.
is required, it is possible to change the
load distribution between the drives
using the load distribution factor. The
reference torque on the slave drive is
then decreased or increased compared
to the reference torque of the master
drive. At the same time the load share
controller maintains the speed difference
between the rolls within given limits.
Using the web-server based operator
interface the process engineer can adjust
the load share factor and limitation for
speed difference at any time also during
the grinding operation.
The plug-and-play system is supplied
fully tested and pre-configured and
is ready for immediate use. Using
webserver functionality, the process
engineer can easily and quickly adapt
or optimise all parameters without any
electrotechnical knowledge. Programming
skills or special equipment knowledge is
not required. The controller is available in
two versions: optimised for the Siemens
controller family Sinamics G150, S120,
GM150 and GH180.
Successful utilisation
KHD Humboldt Wedag, an OEM (Original
Equipment Manufacturer) in the cement
and mining industry, is already using
the load share controller in its Conakry
project. Tests before and after optimising
by the process engineer of KHD show the
benefits of using this controller.
Among other things, the change in the
roll gap and the roll pressure could be
kept in a substantial smaller range.
