Milling Temperature
The effect of milling temperature on the amorphization of mechanically alloyed Cu 30 Ta 70 has been investigated in 1991 by Lee et al. [45] In their experiments, they ball-milled the elemental powders of Cu 30 Ta 70 at two different controlled temperatures of 37°C and 200°C for 100 h under the same milling conditions. They realized that ball milling at …

Temperature Reduction for Ball Mill Optimization | Lechler US
Heat taken away by ventilation systems can accounts for roughly 20% of the total heat discharged by the ball mill. Improving that ventilation system brings more cool air into the inside of the ball bill, gradually reducing the internal temperature. However, the major benefit of using ball mills is the product fineness they can deliver.
