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 mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().
It was found that a rod mill grind to approximately minus 6 mesh produced a feed to the pebble mill which could be ground efficiently with a minus 2-½ plus 1-½ inch pebble. Grinding power requirements totalled 10.7 net kwh/ton of rod mill feed and pebble consumption in the 4 ft diameter pebble mill was 3.1% of the total circuit feed.
Pebble mills are manufactured for long life and minimum maintenance. They are often utilized for secondary grinding in dry or wet applications. Pebble mills typically reduce ores and other materials to 35 mesh or finer, both in open and closed grinding circuits.

Introduce Of Pebble grinding mill A pebble is a clast of rock with a particle size of 4 to 64 equipmentimetres based on the Krumbein phi scale of sedimentology. Pebbles are generally considered to be larger than granules (2 to 4 equipmentimetres diameter) and smaller than cobbles (64 to 256 equipmentimetres diameter). A rock made predominantly

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 ball-mill to improve grinding efficiency. Published in
