The idea of using a mixture of balls and pebbles, at a mill speed suitable for ball-milling, was revisited in this investigation, using a normal spectrum of pebble sizes (19–75 mm). Batch tests in a pilot-scale mill (0.57 m diameter) were used to compare ball-milling to various ball/pebble mixtures.
Pebbled: Mining 101, how we get our metals. Mining is actually a simple process made voluminous by the very low density of the sought-after minerals. A mine with one gram of gold in every ton of earth would be sufficiently rich to take a look at. Getting at that gram is the process I will describe. Mining engineers might well wince at my ...

The U.S. mining industry operates approximately 80 semi-autogenesis grinding mills (SAG) throughout the United States. Depending on the mill size the SAG mills draws between 2 MW and 17 MW. The product from the SAG mill is further reduced in size using pebble crushers and ball mills.
where an approximate figure for the constant is 3.5 for rod mills, 4.0 for overflow ball or pebble mills and 4.5 for grate discharge ball or pebble mills. ç is specific gravity of grinding media (for rods or balls normally 7.85) q is the charge volume in fraction of mill volume (40 % = 0.40) nc is the mill speed in fraction of critical speed

As mentioned earlier, pebble mills are widely used in the North American taconite iron ore operations. Since the weight of pebbles per unit volume is 35–55% of that of steel balls, and as the power input is directly proportional to the volume weight of the grinding medium, the power input and capacity of pebble mills are correspondingly lower ...
