Crushing efficiency is the ratio of the ______________________ ?
Correct answer: A. Surface energy created by crushing to the energy absorbed by the solid
- A. Surface energy created by crushing to the energy absorbed by the solid
- B. Energy absorbed by the solid to that fed to the machine
- C. Energy fed to the machine to the surface energy created by crushing
- D. Energy absorbed by the solid to the surface energy created by crushing
Explanation
Crushing efficiency compares the useful surface energy produced in creating new surfaces with the energy absorbed by the solid. Energy supplied to the machine also includes mechanical and frictional losses, so it is not the denominator in this definition.
