Influence of temperature on the energy efficiency of

1991-2-1  In many mining operations, particularly northern open-pit mines, large seasonal variations in grinding slurry temperature can occur. It is shown in this paper that this temperature shift can cause a winter-time loss in autogenous grinding efficiency of as much as 20% if it is not controlled. Laboratory experimentation indicates that much of this effect is due to increases in slurry viscosity ...
