Grinding circuit optimization and audit | MagotteauxA grinding circuit optimization is then carried out to optimize the machines themselves (e.g. a different design for the internals) or the way they work (e.g. their load or speed). Following a grinding circuit audit and with a view to the grinding circuit optimization, Magotteaux designed several optimization tools. Among these are.grinding circuit optimisation,grinding circuit optimisation,comminution circuit optimisation - CEECoptimisation is project specific, cash flow for the existing asset is typically targeted first, particularly in tough financial times, and project economics are targeted second, as the latter is often more capital intensive. Optimising the throughput of the grinding circuit can have economic benefits well beyond the processing plant.
