The standard Bond Ball Mill Work Index test procedure is firstly to stage crush the feed to minus, and size a representative sample. The test then involves a series of batch grinds in a standard Bond mill. A Bond mill is by, with rounded corners, a smooth lining, and runs at 70rpm.

The ball fi mill work index is con rmed at 16 kWh/t. The operating fi work index, though, is in the range of 21 kWh/t to 25 kWh/t showing high ineffi ciency. This raises the point that, in some cases, the Bond EF4 oversize factor calculation is not suf cient to compensate fi for the milling inef ciencies that arise.

Average Ball Abrasion For calculating of the average ball abrasion, average weight of balls after abrasion test was deduced by average balls weight before abrasion. At first, ball filling in the mill was spot 1% and the number of balls in mill was estimated as shown below (Equations 7, 8 and 9). 𝐴𝑏 = = g (7)

CALCULATION OF MAXIMUM BALL SIZE FOR BALL MILL . Jun 25, 2018· Mill effective diameter = m . 335 is a constant used for dry grinding with steel balls in the mill. Actual size of media is taken is lower than the calculated value. It is around 80 to 90 mm.

Optimization of mill performance by using online ball and pulp measurements by B. Clermont* and B. de Haas* Synopsis Ball mills are usually the largest consumers of energy within a mineral concentrator. Comminution is responsible for 50% of the total mineral processing cost.
