The grinding circuit usually consists of aSAG or AG mill and one or two ball mills. Grinding is continuous and fully integrated with subsequent flotation operations. SAG or AG mills. The crushed products are ground in SAG or AG mills. The self-grinding machine can grind ore without grinding media such as iron ball, or steel rod, as long as the hardness of the ore is sufficient for the rolling ore to grind by itself.

In grinding circuits,energy is wasted when particles are ground to a size finer than is necessary. Such overgrinding can be caused when particles are retained in the circuit for too long and continue to be ground even after they have reached the target product size of the circuit. There are two factors that contribute heavily to overgrinding: (1) inefficient classification returning a large fraction of the finest …

Apr 01, 2001· The Kubakagrinding circuitwas designed using SPI calibration work (originally presented at the SAG ’96 conference), perhaps the first such installation to be planned using these calculations. O ne key to using SPI during the design of agrinding circuit, is to use the value of the hardest ore, not an average hardness.

This type of grinding is the most common circuit found in mineral processing facilities mainly because a lot of ores and product requirements are not suitable for open circuit grinding. Some advantages presented by grinding in closed circuit are that this arrangement usually results in higher mill capacity and lower power consumption per ton of product it eliminates overgrinding by removing
