Grinding media may be either pebbles, rock, or the new development known as Coors Alumina Ceramic high density grinding media. The media charged to a pebble mill should be between 50% to 55% of the mill volume.
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.
Pebble Mill A world-class medical and life sciences destination Calthorpe Estates vision was to create 500,000 sq ft of world-class medical and life science facilities, in addition to community access sporting uses, at the former BBC Pebble Mill site in the heart of Edgbaston Medical Quarter on the Estate.

Pebble mills may be used when metal balls must be avoided. Autogenous grinding (AG) and semi-autogenous grinding (SAG) mills use the material to be ground as the grinding media. Autogenous grinding mills use larger rocks to impact and break smaller rocks as the mill rotates. Semi-autogenous mills are basically the same autogenous mills, but ...

If built, Pebble would be the largest mine in North America. Pictured above: Goldstrike Mine, Nevada. The Pebble deposit is a massive storehouse of gold, copper and molybdenum, located in the headwaters of the Kvichak and Nushagak Rivers, two of the eight major rivers that feed Bristol Bay.
A host of famous faces and shows have featured at Pebble Mill. Amongst them are Pebble Mill at One, which ran from 1973 to 1986, and Good Morning With Anne And Nick, which featured Anne Diamond and Nick Owen. The firm's development director, Ralph Minott, said: "This represents the final piece of the jigsaw for Pebble Mill.
crushers, smooth roll crushers, toothed roll crushers, and hammer mills are used for secondary crushing, which further reduces particle size to 3 mm (0.1 in.) or less. For some applications, tertiary size reduction is necessary and is accomplished by means of ball, rod, or pebble mills, which are often combined with air separators.
There is the temptation, held by some, to open up the pebble ports to, say, 75-90 mm from 50-65 mm. Also, any increase in the nominal aperture of pebble ports automatically alters the power split between primary and secondary mills and places a heavier load on the secondary mill to the point where:

The pebble weight is 5-25% of the total feed to the plant, depending on the strength of the pebbles. Sometimes waste rock of high strength is used as pebbles. Pebble mills should always be of the grate discharge type. The energy that can be converted in a mill depends on the total weight of the grinding charge.
