Comminution Rod mill: used to grind the product from a crushing circuit (typical particle size of 3 cm) and grinds it to a size fine enough for a ball mill to handle (0.600 lbs . grinding takes place preferentially on coarser particles produce less fines than ball mills Media: steel rods almost as long as the mill and can weigh 400.5 cm).


On the other hand, the industrial practice of the vertical roller mill is a continuous grinding process, as the ground very fine particles are removed by a separator located in the mill. Therefore, it can be assumed that the top sizes of the calcite samples will be broken according to the first-order law.

Grinding - Mineral Processing

The ball mill is the fine grinding machine connect the SAG or AG mill and flotation machine. Ball mills produce fine particles with a uniform size for flotation, its grinding medias commonly are steel ball. The ball mill rolls grinding media together with the ore, as the ore grinds, these balls initially 5-10 cm in diameter but gradually wear out.

The fine particles are pumped via a sump (8) to a secondary hydrocyclone (9), and the larger particles return to the SAG mill (4) for further grinding. The secondary hydrocyclone (9) further classifies the slurry, with the coarse particles being directed to the ball mill (14) and fine particles reporting to the trash screen (10).

11.23 Taconite Ore Processing

mineral to allow for a high degree of mineral liberation. Most of the taconite used today requires very fine grinding. Prior to grinding, the ore is dry-crushed in up to six stages, depending on the hardness of the ore. One or two stages of crushing may be performed at the mine prior to shipping the raw material to the processing facility.


Stirred bead mills find application in a number of industries where there is a need for very fine grinding or particle dispersion. In the minerals industry this type of mill is becoming increasingly important due to processing of ore bodies which are fine-grained and require milling to fine sizes for effective mineral liberation.

In mining, for example, very fine particles can interfere with separation processes, such as froth flotation, and might result in loss of valuable components. In other operations, the objective might be to produce very fine particles. Sometimes, as in sugar grinding, very fine particles are agglomerated to increase the share of larger particles.


The HIGmill's rotating grinding discs stir small ceramic beads, which wear down ore particles to a size where even very fine grained minerals can be liberated. The tall, narrow shape of the mill and the configuration of its discs produce a very efficient grind, according to Steve Schmidt, Outotec's commercial product manager for HIGmills.

This is called the liberation size. Grinding to a size much smaller than the liberation size in turn brings some disadvantages. Besides the higher power consumed in grinding, very fine particles or slimes reduce the efficiency of recovery in the flotation process. Slimes also add to the pollution control problems.

With the exception of some iron ore tailings, it is probable that most mill tailings will be very fine-grained materials with 50 percent or more of the particles passing a 0.075 mm (No. 200) sieve. Other physical properties of mill tailings include specific gravity, unit weight, and moisture content.


Fine particles float poorly and less selectively under normal flotation conditions and have detrimental effects on the recovery of other minerals.

A method for creating ultra-fine particles of material using a high-pressure mill is described. The method includes placing a material in a first chamber and subjecting the material to a high-pressure liquid jet to divide it into particles. These particles are then transferred to a second chamber in which they are subjected to cavitation to further divide the particles into relatively …


Very fine particles (usually means the particle size of ore less than 5-10 μm), due to the small weight of the mineral particles, is easy to adhere to the surface of the coarse particles, then reducing the floatability of the coarse particles. So if the particles size of ore are too coarse or too fine, the recovery rate of ore would reduce.
