The method entails replacing a fraction of the volume of steel balls in ballmilling by criticalsize pebbles emanating from a SAG mill, which are normally crushed and recycled. The method was tested for milling a silicate ore (F 80 = mm, BWI = 15 kWh/t) and a platinum ore (F 80 = mm, BWI = 21 kWh/t).

This finish removes all light surface scratches, mill marks, and burrs. Orbital sanding finishes are best for parts above six inches. Tumbling (see below) is recommended for smaller parts. Like bead blast, sanding random swirl finishes are excellent for preparing surfaced before anodizing to create a matte nonreflective appearance.

Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 3045%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.

Grinding tests were conducted on an oxidized coppercobalt ore using a pearshaped ball mill. Twelve monosized ore fractions were prepared and wet ground batchwise. The mill was run for to 30 min intervals. The shortest interval provided data more closely related to the breakage function (B) because less secondary breakage was hypothesized.
