Metallurgical ContentTube Mill CapacityPebble Mill CapacityPEBBLE MILL LINERSPEBBLE 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
A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 50 % of the mill volume and its size depends on the feed and mill size.

The terms highspeed vibration milling (HSVM), highspeed ball milling (HSBM), and planetary ball mill (PBM) are often used. The commercial apparatus are PBMs Fritsch P5 and Fritsch Pulverisettes 6 and 7 classic line, the Retsch shaker (or mixer) mills ZM1, MM200, MM400, AS200, the Spex 8000, 6750 freezer/mill SPEX CertiPrep, and the vibrational ball mill.
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.
The following are factors that have been investigated and applied in conventional ball milling in order to maximize grinding efficiency: a) Mill Geometry and Speed Bond (1954) observed grinding efficiency to be a function of ball mill diameter, and established empirical relationships for recommended media size and mill speed that take this factor into account. As well, mills with different
However, continuous pilotplant tests were disappointing, because the consumption of small pebbles was too high. The idea of using a mixture of balls and pebbles, at a mill speed suitable for ballmilling, was revisited in this investigation, using a normal spectrum of pebble sizes (1975 #181;m).
The functional performance equation for ball milling was first presented in 1988. It has now been used successfully in a substantial number of mineralprocessing plants. This powerful, yet simple, tool provides a new level of understanding of closed circuit grinding.
A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles, and stainless steel balls.
#0183;#32;The pebble mills need to be much larger than ball mills, to draw the same power, and hence it is not easy to change from one type of milling to the other. Most mining companies have opted for the safe option of ballmills for secondary grinding.
