    Higher grinding efficiency is obtained since there is less void space in a rod charge compared to any other grinding media. This also results in lower steel consumption. Our heavy rigid construction combined with the open end feature insures maximum operating time. Grinding rods can be kept in maximum working condition since worn rods may easily be withdrawn. The Rod Mill is probably the

  • Rod Mill - an overview ScienceDirect Topics

    Rod mills have an industrial yield that is less than that of a ball mill, which explains the fact that balls have a much larger grinding surface than rods. The power needed to operate a rod mill could exceed 30% of the power used in a ball mill. When they are worn, rods must not stretch but break in rather small pieces, so that they can exit the mill. The energy consumed by rod mills could be ...

    OverviewGrinding machinesGrinding lawsTypes of grinding millsSee alsoExternal links

    In materials processing a grinder is a machine for producing fine particle size reduction through attrition and compressive forces at the grain size level. See also crusher for mechanisms producing larger particles. In general, grinding processes require a relatively large amount of energy; for this reason, an experimental method to measure the energy used locally during milling with different machines was recently proposed.
