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.
In all ore dressing and milling Operations, including flotation, cyanidation, gravity concentration, and amalgamation, the Working Principle is to crush and grind, often with rob mill or ball mill, the ore in order to liberate the minerals.

Many years ago pebble mills were actually used flint rocks as the grinding media. Now we use high-alumina brick and grinding media with 90%-96% aluminum oxide content. The new pebble mills are lined with aluminum oxide (alumina) brick, which is very hard (9 on the Mohs hardness scale) and will not contaminate most products.

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.

The lining for pebble mills may be either standard types of metallic lining, or for the prevention of iron contamination non-metallic materials can be used. Such non-metallic lining material is Jasper, Silex, or other tough, hard natural stone. A recent development is the Coors high-strength Alumina ceramic mill lining brick.
Sepor's batch ball and rod mills are designed to give size reduction of laboratory quantities of minerals and ores. Feed size should generally be -1/8″, for ball mill and -1/2″ for rod mill. They are of a sturdy, rugged design to handle frequent use with hard...

Compare Pebble Mill at One to similar programmes of the era and it absolutely knocks them out of the park. Anyway. What I would like to respectfully ask is that this forum isn't use to diss the past. There may well be people reading this forum who worked on these shows, or at least worked at The Mill.
Pebble Mills. In some cases it is suitable to use screened fractions of the material as grinding media. Such mills are usually called pebble mills, but the working principle is the same as for ball mills. As the power input is approximately directly proportional to the volume weight of the grinding media, the power input for pebble mills is ...
Pebble mill. A tumbling mill that grinds or pulverizes materials without contaminating them with iron. Because the pebbles have lower specific gravity than steel balls, the capacity of a given size shell with pebbles is considerably lower than with steel balls.

A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering.It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about its axis. T

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:
