What are the differences between ball mill and rod mill 08 03 2021· Ball mill and rod mill are suitable for different materials 1 Selection by material s hardness Ball mill has a strong adaptation of material and it is suitable for grinding hard materials such as slag iron ore copper ore etc Rod mill is suitable for grinding brittle material such as rare metals 2 Selection by required particle size
paragominas ball mills sag mills A SAG mill is generally used as a primary or first stage grinding solution Attrition between grinding balls and ore particles causes grinding of finer particles SAG mills are characterized by their large diameter and short length as compared to ball mills SAG mills are primarily used at gold copper and platinum mines with applications also
Mill Critical Speed DeterminationThe Critical Speed for a grinding mill is defined as the rotational speed where centrifugal forces equal gravitational forces at the mill shell s inside surface This is the rotational speed where balls will not fall away from the mill s shell Result #1 This mill would need to spin at RPM to be at 100% critical speed Result #2 This mill s
RESPONSE OF PRIMARY GRINDING MILL PERFORMANCE TO grinding mill and AG/SAG mills MILL MONITOR SYSTEM AND RECENT ENHANCEMENTS The key features of the original prototype of a ruggedized continuous mill monitoring system were described in Campbell et al 2006 A number of changes have subsequently been made to the various components of the mill monitor during evaluation of the prototype system
