Optimization of mill performance by using online ball and pulp measurements by B. Clermont* and B. de Haas* Synopsis Ball mills are usually the largest consumers of energy within a mineral concentrator. Comminution is responsible for 50% of the total mineral processing cost. In today's global markets, expanding mining groups are trying

FESEM Analysis Ball Milled Powder. The morphology of SiC particles after 40-h of milling time, as observed under FESEM is shown in Fig. 2.The particles are greatly fractured and larger fraction of nano size particles in 40-h milled samples are observed, this could be due to excess work hardening and enhancement of brittleness of the particles by milling [21, 22].

this work, the high-energy planetary ball mill process is modeled using the software Automated Dynamic Analysis of Mechanical System MSC Adams [ 22 ]. Figure 2 illustrates a schematic of a high-energy planetary ball mill equipped with two cylindrical vials. The mill was powered by a 0.37 kW electric motor.

Ball mills are simple in design, consisting of horizontal slow rotating vessels half filled with grinding media of ¼" to 1.5". The particles to be milled are trapped between the grinding media or balls and are reduced in size by the actions of impact and attrition.

Sorrenti9 In particular they classify the ball mills in two groups depending on their operation mode: direct and indirect milling. In the rst case rollers or mechanical sha s directly act on the particles and transfer the kinetic energy. In the second case the kinetic energy is rstly transferred to the mill body and then to the grinding medium.

Mechanical ball mills. With mechanical ball mills, material is discharged mechanically through a discharging box. The material is usually further conveyed to a dynamic separator, which together with the mill forms a mechanical ball mill grinding plant. These grinding plants are used to comminute relatively dry materials to a very high fineness.
