The rule for speeds applies regardless of the type of grinding media. A Pebble Mill the same size as a Ball Mill is expected to run at a slightly faster speed. This is due to the smaller inside diameter of the Pebble Mill with its lining, which is lacking in the Ball Mill.

[Show full abstract] proposed to convert existing ball mills to "pebble" mills which would use coarse ore from the crushing circuit or smelter slag as grinding media. The capacity of the ...

Pebble Mill Application and Design. Pebble mills also known now as ceramic lined mills are a type of ball mill and are used in the size reducing or milling of hard materials such as minerals, glass, advanced ceramics, minerals for ceramics and semiconductor materials down to 1 micron or less.

Ball mills are often used as secondary grinding mills and for regrinding of middlings in concentrators. Ball mills can be of the overflow or of the grate discharge type. Overflow discharge mills are used when a product with high specific surface is wanted, without any respect to the particle size distribution curve.

The control of ball-mills is relatively simple in comparison (i.e. addition of balls to maintain power and control of the cyclones and pulp density). Pebble-milling is used on some mines for secondary grinding, to reduce operating costs. However, the availability of pebbles is essential and pebble storage is required.

Ball-mills are used widely for secondary grinding. Loveday (2010) reported on laboratory tests in which small pebbles (7-25 mm) were used in various proportions with balls. The optimum proportion of pebbles, by volume, was found to be about 25%. Substantial savings in power and ball consumption were achieved, with no loss in grinding capacity.

Ball mills vary greatly in size, from large industrial ball mills measuring more than 25 ft. in diameter to small mills used for sample preparation in laboratories. Rod mills are similar to ball mills and use metal rods as the grinding media. Pebble mills use rock pebbles as the grinding media to cause friction and attrition between the pebbles ...

The Pebble Mill. Pebble Mills, also known as Ceramic Lined Mills, operate in exactly the same manner as Ball Mills but instead of using balls, they use rock, metal or alumina pebbles. Pebbles are an excellent grinding material to use on steel products (particularly stainless steel).

Rod grinding mill: a rod mill is also called slitting mill. It has rod of different diameter and sizes inside a drum. The rotation of the drum causes friction and impact of the materials with the rods. The impact creates fine shape of particles. Pebble grinding mill: in pebble mill, the drums roll faster creating more friction.

PEBBLE MILL GRINDING MEDIA Essentially tube mills and pebble mills may be considered as ball mills, the basic difference being that the ratio of length to diameter is greater. Usually the shell length is between 2 and 5 times the diameter. These mills are primarily used to grind various materials to 100 mesh and finer.
