Optimization addresses the grinding process, maintenance and product quality. The objective is to achieve a more efficient operation and increase the production rate as well as improve the run factor. Consistent quality and maximum output with lower specific power consumption results in lower operating costs per unit of production.
Grinding wheels are dressed to restore or change their ability to remove stock or generate a specific finish. If the wheel is being used to remove stock, the grinding face is dressed to expose new and sharp cutting points, allowing the wheel to cut with a higher material removal rate. However, the tradeoff is that the finish may be unfavorable.

Every second counts with your grinding circuit optimisation . Grinding mills are the main workhorses in the majority of comminution circuits globally. They need to be fed and kept working round the clock. But challenges can arise when capacity is not optimised causing unnecessary downtime and liner wear.
Recommendations for achieve these goals in ball mill grinding circuit: In a plant with hydrocyclones is correct to use higher circulating load (~400%) to diminish residence time in the mill. For instance, versus 300% CL around 5% energy saving is obtained and the product has 5%-10% less -10um fraction (see 4th Grinding and Classification Law)
