Soft ore Work Index 13 = 100,000/90,000 = 1.1 kwh/t Hard ore Work Index 16 = 100,000/65,000 = 1.54 kwh/t. For the purposes of this example, we will hypothesize that the the crushing index of the hard ore with the increased energy input of 1.54 kw/t reduces the ball mill feed size to 6,500 micrometers.
Reason: This is a common problem mining ball mills face, resulting in low productivity and low ore processing efficiency. One reason may be the improper design of the grinding chamber, which affects the flow of materials and reduces grinding efficiency. Additionally, worn or damaged liners can hinder the grinding process by reducing the …

Grinding Mills: Grinding mills, such as ball mills and rod mills, are commonly used for grinding iron ore. These mills contain grinding media (steel balls or rods) that tumble and impact the ore, causing it to break into smaller particles. The choice of grinding mill depends on factors such as the desired product size, capacity …
1. Introduction. The Run-of-mine composition strongly affects autogenous mill operation. However, the effects of a varying ratio of hard and soft components in mill performance are not described by the current generation of AG/SAG models (Stange, 1996).For example, current JKSimMet models (Napier-Munn et al., 1996) assume a …
