    2021. 4. 16.· A linkedin group was recently discussing this by asking: I’ve tried to estimate AG/SAG Mill power requirements using several different methods: (1) Using the results of SMC data (2) Using SAG Power Index (SPI) data (3) Using the 1989 Barratt method updated on Alex Doll’s Web site (February 16, 2015)

  • Energy requirement for fine grinding of torrefied wood

    2010. 7. 1.· Fine grinding of natural wood requires a lot of energy: about one-sixth of its LHV. Natural spruce requires less grinding energy than natural beech (respectively 750 kWh/t and 850 kWh/t). Grinding energy is amazingly decreased by torrefaction. For example, it is possible to spare 90% of beech grinding energy at 280 °C.
