The result revealed that the energy required by a ball mill, highpressure homogenizer and twin screw extruder were,, and 5 kWh/kg of biomass, respectively . Kim et al. showed that a large amount of energy was needed by the planetary ball mill for grinding rice straw compared to the attrition mill.
Effects of the speed ratio on the efficiency of planetary mills
Planetary ball mills provide high energy density due to the superimposed effect of two centrifugal fields produced by the rotation of the supporting disc and the rotation of the vials around its own axis in the opposite direction [1]. During operation, the grinding balls execute motion paths that result in frictional and impact effects.
