  • Optimal design of a secondary milling circuit for treating chromite

    Separate milling of the light and heavy fractions made it possible to grind the silierich fraction finer and to avoid overgrinding of the chromite. The total milling energy was redistributed between the silies and chromite ball mills with 88% of the energy input to the silies mill and 12% to the chromite mill thus reducing

  • Effect of pin tip velocity, ball density and ball size on grinding

    Studies were made of the grinding kinetics of chromite ore in a stirred ball mill. Grinding tests were carried out using material in discrete size ranges (53 + 38 μm and 38 + 25 μm) and for material conforming to a natural spread of sizes (100 μm). Tests conducted on the discretely sized material were used to establish the

    This involves grinding the chromite concentrate in a ball mill, pelletising a mixture of concentrate, coke, fines and bentonite which acts as a binder, then heating the pellets in a steel belt sintering furnace. In sintering, the pellets are heated to form strong bonds between the chromite grains to yield and agglomerate material.
