GRINDING OPTIMISATION Adapting to the market

Moreover, as the new mill is able to use carbon-neutral additives and reduce CO 2 emissions by 94,000tpa, it meets Republic Cement’s drive for sustainable production. In addition, the power required by the grinding facility is 40 per cent lower when compared to existing cement mills operated by the company.

Throughput optimisation in milling circuits

For example, you need a good fast responding control of the mill feed rate. If the mill feed setpoint is changed, then the actual feed rate needs to stabilise at the new target in a short period of time. The feed rate setpoint can then be tied into a SAG mill power optimisation strategy. SAG Mill Discharge

Crushing Vs Grinding - Minerallurgy

The Difference between Crushing and Grinding in mineral processing Both crushing and grinding are size reduction processes. They are known as milling operations Introduction The size reduction operation in the plant takes place as a sequence of crushing and grinding processes. In crushing, particles are reduced in size to such a level that grinding can be conducted, while grinding allows ...

SAG Mill Optimization using Model Predictive Control

Control of -SemiAutogenous Grinding SAG mill weight is an example of an important process that exhibits many of these aspects. Maintaining the SAG mill weight at the optimum value is critical for achieving maximum grind rate efficiency and mill production Powell, M.S., van der Westhuizen, A.P., and Mainza, A.N. 2009 .
