| The automation of aggregate facilities can maximise productivity
without reliance on manual observation and adjustment. It is unfortunate,
but variations in operator skill can reduce plant performance
and production.
Optimisation and automation can be selectively applied to specific
circuits, or to an entire operation to:
- maximise crusher performance
- monitor equipment diagnostics to identify problems before
a break down
- equally distribute power demands for optimal load sharing.
Roberts & Schaefer Company (R&S) understands the balance
between excessive complexity and operator capabilities. The ultimate
goal is maximising production at the most efficient operating
cost.
Projects representing our experience are highlighted below.
