The magnetic products from the LIMS and SLon are sent back to the secondary ball mill for regrinding, and the milled product returns to the primary cyclone classifier. The fine size fraction is about 90% 75 μm and is processed using drum LIMS separators and SLon magnetic separators in series to take out the magnetite and hematite, respectively.

Fig. 6: Levin test for the ball mill The Levin test for fine ball mill product predicts a net specific energy requirement of kWh/t to grind from an F80 of ~400 µm (AG mill/magnetic separator product) to a P80 of 34 µm. An additional kWh/t would be needed to reduce the plant feed P80 of 770 µm to the test feed P80 of 420 µm,

Reason: This is a common problem mining ball mills face, resulting in low productivity and low ore processing efficiency. One reason may be the improper design of the grinding chamber, which affects the flow of materials and reduces grinding efficiency. Additionally, worn or damaged liners can hinder the grinding process by reducing the effective impact between the ball and the material.
