Grinding Mills and Their Types – IspatGuru
· Ball mill (Fig 1) is same kind of mill as rod mill, except that it is filled with balls instead of rods. Because of balls have greater ratio of surface area than rods they are more suitable for fine grinding. Balls are also lighter, so the kinetic energy of a single dropping ball is smaller than a rod. The lining material is of great importance as there is a significant amount of wear taking ...
(PDF) SIZE REDUCTION BY GRINDING METHODS
Ball mills are used for wet grinding iron ore, g old/copper ore, nickel ore and other ores, as wel l as lime/limestone for flue gas desulphurisat ion systems, coal and other raw materials. Rod mill :
Wet Grid Ball Mill
Grid ball mill is widely used in smashing all kinds of ores and other materials, ore dressing and national economic departments like building and chemical industries etc. The size of ore shall not exceed 65mm and the best feed size is under 6mm. The effect in this job is better than coarse grinding. Grid ball mill consists of the shell, feeding part, discharging part, main bearing, lubriing ...
Grinding Circuit
Hydrocyclones have come to dominate classifiion when dealing with fine particle sizes in closed grinding circuits ... A combination of rod mill and ball mills are then used if the ore must be ground below 325 mesh (45 μm). Instead of grinding the ore dry, slurry is used as feed for rod or ball mills, to avoid dusting. Oversize and undersize materials are separated using a screen; oversize ...

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. AG/SAG 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 mill.
SmallScale Tests to Characterise Ore Grindibility
but for AG/SAG mill analyses the standard 14mesh () sieve is typically used. The rod mill work index is computed with an equation very similar to that of the ball mill test, as follows: It is common to observe a difference between the rod mill and ball mill values for a given ore type. These differences may be caused by a variation in ore

Ball Mills
Ball Mills are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed system, with oversize material continuously being recirculated back into the mill to be reduced. Various classifiers, such as screens, spiral ...
Rod mills, how they function
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 to Rod mills accept feed up to about 50 mm (2 in.) and produce a product in the size range of ...
Mineral processing
The primarily used equipment in crushing are jaw crushers, gyratory crushers and cone crushers whereas rod mills and ball mills, usually closed circuited with a classifier unit, are generally employed for grinding purposes in a mineral processing plant. Crushing is a dry process whereas grinding is generally performed wet and hence is more energy intensive.
Rod Mills
· The Steel Head Rod Mill (sometimes call a bar mill) gives the ore dressing engineer a very wide choice in grinding design. He can easily secure a standard Steel Head Rod Mill suited to his particular problem. The successful operation of any grinding unit is largely dependent on the method of removing the ground pulp. The Steel Head Rod Mill is available with five types of discharge trunnions ...

Throughput optimisation in milling circuits
SAG mill discharge control is quite involved due to few interactive variables, such as mill discharge sump level, classifiion hydrocyclone variables (feed density, flow and pressure) and water feed rate to the sump. Model predictive control (MPC), which is a multiinput multioutput (MIMO) controller, is very suitable for this purpose. If a particle size analyser is installed it can be ...
