EF1 – Dry Grinding – for the same range of work, dry grinding requires 1.3 times as much power as wet grinding. EF2 – Open Circuit Grinding – when grinding in open circuit ballmills, the amount of extra power required, compared to closed circuit ball milling, is a function of the degree of control required on the product produced. The inefficiency factors for open circuit ...

"Most of the strength of a cylinder comes from the outer portions. I think the contribution goes like the cube of the radial position. So, if you took asolid rodand drilled out a half the volume from the center, you do not lose half the strength. Strength to weight ratio is better for a hollow pipe than asolid rod."
