Fig. 6: Levin test for the ball mill The Levin test for fine ball mill product predicts a net specific energy requirement of 52.5 kWh/t to grind from an F80 of ~400 µm (AG mill/magnetic separator product) to a P80 of 34 µm. An additional 2.3 kWh/t would be needed to reduce the plant feed P80 of 770 µm to the test feed P80 of 420 µm,

A magnetite middling was used to compare the liberation effect of the magnetite fine ground by a vertical stirred mill and a ball mill. The magnetite middling contained a high content of magnetite intergrowth with the particle size mainly distributed in the range of 40–150 μm.The new generated −38 μm products were concentrated by …
The size of the blind trommel and magnetic circuit can be varied to retrofit an existing ball mill and available space at the discharge. The magnetic circuit is designed to provide maximum strength for high slurry throughputs and up to 4 inch diameter grinding balls. The trunnion magnet can be configuration for reversing or bi-directional mills.

The …
The iron ore deposits in the Labrador City area occur as specular hematite and magnetite, generally in the ratio of 65:35. IOC has mineral reserves and resources of 1.1 billion tonnes and 1.7 billion tonnes, respectively, with an average grade of approximately 38% iron.
For the grinding of the magnetite ore, two types of mills were chosen. First, we present the planetary ball mill (PM 100, Retsch ), which is a device for lab-scale experiments in research such as mechanochemistry, ultrafine colloidal grinding on a nanometer scale, and mixing and homogenizing soft, hard, brittle, or fibrous material.
It can be seen that, for both ceramic and steel ball grinding, as the feed size decreases, the value of. a increases. This trend is particularly significant when the …
