A very high impact opportunity to increase your ball mill tonnage. A conversion is cheap in price as you can read in the footer. The cost of a ball mill conversion from overflow to grate discharge is 'fairly' affordable at 65,000 for a 13′ x 15′ mill. This is only for the discharge head, grates and pulp filters (rubber).

The final product from these large regrind ball mills using small grinding media will be approximately 28 microns. The mills will produce a fine ore stream which enters magnetic separators to become a concentrate. The concentrate will be thickened and stored before being pumped 25 kilometers to the port, where it is filtered to reduce moisture.

As all we know SAG uses mostly impacts, however ball uses both impact and good amount of abrasion that is supposedly take all the added collector from the surface. Single categorization for tumbling mills as impact is quite insufficient. In addition, from this article it is understood that ball milling is quite inefficient due to high abrasion.

For one, the ball charge and tumbling motion of a Bond mill is inefficient in this range. Also, screening well at 500 mesh is not easy. Many people overlook the impact of screening on the Bond results but the impact can be significant. The other issue is that nowadays fine grinding is not performed in tumbling mills for energy efficiency reasons.

Where regrinding is possible, the price in the secondary and tertiary use goes down significantly. No new raw material is necessary, the diameters are already available, only the cutting edges are reground. Before purchasing a tool it is worthwhile to find out whether regrinding is possible. If it is, it reduces the overall cost of a tool.
