o < 20% of energy absorbed is reckoned to be converted to useful grinding: the bulk is lost as heat, noise, equipment wear & vibration; o For ball mills, only 3 – 6% of absorbed energy is utilized in surface production, the heat generated can increase mill temperature to > 120⁰ C & causes excessive gypsum dehydration & media coating if mill ventilation is poor.

For a concrete slab it is common to use the slab thickness and the concrete properties (e.g., Ec) to define the diaphragm stiffness; it may be appropriate to apply a cracked factor to Ec. For concrete fill on metal deck it is common to ignore the contribution of the metal deck, and only use the concrete properties to define the diaphragm stiffness.
