Work index is the gross energy (kWh/tonne of feed) necessary to reduce a very large feed to such a size that 80% of product particles will pass through a 0.1 mm screen. The value of work index determined for wet grinding should be multiplied with ______________ to get the same for dry grinding?
Correct answer: C
Explanation
The work index for wet grinding needs to be multiplied by 1.34 to estimate the equivalent value for dry grinding.
