Rod mills have an industrial yield that is less than that of a ball mill which explains the fact that balls have a much larger grinding surface than rods The power needed to operate a rod mill could exceed 30 of the power used in a ball mill When they are worn rods must not stretch but break in rather small pieces so that they can exit

The feed enters one end of the ball mill and discharges out the other end 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

The ball mill grind various ores and other materials either wet or dry There are two kinds of ball mill grate type and overfall type due to different ways of discharging material There are many types of grinding media suitable for use in a ball mill including ceramic balls flint pebbles and stainless steel balls

81 Grinding 811 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 particles of media the rods balls or pebbles

The mill product can either be finished size ready for processing or an intermediate size ready for final grinding in a rod mill ball mill or pebble mill AGSAG mills can accomplish the same size reduction work as two or three stages of crushing and screening a rod mill and some or all of the work of a ball

The grinding medium may be steel rods balls or rock itself Media ball sizes for example range from about 20 mm for fine grinding to 150 mm for coarse grinding Tumbling mills are typically employed in the mineral industry for primary grinding ie stage immediately after crushing in which particles between 5 and 250 mm are reduced in

RoM Ball mills like SAG mills utilise coarse rocks in the RoM feed as grinding media but with 25 – 40 steel balls added which is advantageous when the coarse fraction in the RoM feed is

Ball mills tumble iron or steel balls with the ore The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds The feed to ball mills dry basis is typically 75 vol ore and 25 steel The ball mill is operated in closed circuit with a particlesize measurement device and sizecontrol cyclones

Rod mills are very similar to ball mills except they use long rods for grinding media The rods grind the ore by tumbling within the the mill similar to the grinding balls in a ball mill To prevent the conditions leading to rod charge tangling the length to diameter ratio is maintained at 14 to 16

Autogenous AG grinding mills involve no grinding media as the ore itself acts as the grinding media Our ball mills are the most robust design in the industry available with either geared or gearless drive arrangements The costeffective FT Series mills are smaller gear

The diameter of industrial ball mills is 24 feet and the motors are 22 MW However small versions can be seen in labs as well Rod mill In rod mills a spinning drum causes attrition and friction between ore particles and steel rods Ball mills are more commonly used than rod mills to grind minerals

Common examples are rod and ball mills both of which are of the rotary drum type which rely on internal grinding agents to achieve their milling action Unlike the ball mill which utilizes a large number of hardened steel balls to impart the grinding action the rod mill uses steel rods lying within the drum and parallel to its axis
