When the proportion of pebbles in the mill charge was low (up to 30%), the larger pebbles wore away significantly faster than expected, based on a constant surface wear rate. This could be due to size segregation in the mill. CITATION. Nkwanyana S and Loveday B. Addition of pebbles to a ballmill to improve grinding efficiency.

However, the availability of pebbles is essential and pebble storage is required. 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.
Grinding Media Grinding media are the means used to crush or grind material in a mill. It comes in different forms such as alumina oxide balls, ceramic cylinders, or soda lime glass. At Norstone Inc., we offer all types of medias used for grinding, deagglomeration, polishing, deburring, fillers, proppants, spacers, refractory beds and shot peening.
Ceramic ball mill linings will eventually wear down and need replacement. Even old pebble mills with Burrstone linings can be relined with highalumina brick. We tear out and dispose of the old brick, check the steel shell thickness, repair or replace and thin or corroded section and the install the new brick lining.

Figure Media motion in the tumbling mill. Grinding Grinding action Industrial grinding machines used in the mineral processing industries are mostly of the tumbling mill type. These mills exist in a variety of types rod, ball, pebble autogenous and semiautogenous. The grinding action is induced by relative motion between the
A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints. Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium.
A ball mill crushes solids into a fine powder within a rotating drum, using balls as the grinding medium. Applications. Ball mills are found in settings as diverse as laboratories and mines, among others. Technologies. Ball mills can grind in either a wet or a dry environment.
Ball Mills, generally unlined, steel mills and Pebble Mills, generally lined mills of porcelain, rubber, plastic, etc. are larger versions of these apparatus. Vibratory Mills utilize a bowl or cylindrical chamber that moves the media against the material by means of vibrating action. Vibratory Mills can be urethane lined, stainless steel or steel.
Various types of ball mill designs are available to suit different application. These could include but not be restricted to coal mining grate discharge, dry type grinding, wet mineral grinding, hightemperature milling operations, stone pebble milling. 【Working principle of ball mill】

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.
Ball mills – with small balls or cylpebs – can produce the finest product of all tumbling mills. 80% minus 74 microns is a normal requirement from the concentrators. The CRRK series of wet grinding ball mills are tabulated below. PEBBLE MILLS. No steel grinding media is used in a fully autogenous mill.

Ball mill. A typical type of fine grinder is the ball mill. A slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grind material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30%.

A special case of the grate ball mill is known as the pebble mill. Media include porcelain balls. Nonmetallic such as flint pebbles and sometimes the ore itself. (When the ore itself is used as media, the mill is termed autonomous.) The bulk density of a pebble charge is less than that found in steel grinding .
