Energy Use of Fine Grinding in Mineral Processing ...

Dec 18, 2013  For vertical stirred mills such as the SMD and tower mill, both SI s and SI g are non-zero. For horizontal stirred mills such as the Isamill, net gravitational SI is zero due to symmetry along the horizontal axis. Therefore, for horizontal stirred mills, only SI s need be taken into consideration.
