Rod Mill Design Calculations
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 ball mills, 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.

What Are the Differences between Dry and Wet Type Ball Mill?
The wet ball mill has a low noise, and low environmental pollution. The wet ball mill has a simple transportation device with less auxiliary equipment, so the investment is about 5%-10% lower than that of a dry ball mill. The grinding particle size is fine and uniform. The wet ball milling can not only grind agglomerate into fine particles, but ...

How to design a Ball Mill
You also need a rod mill work index to design a ball mill operating on a coarse feed, above about 4 mm. Q1: You design for a typical percentage of critical speed, usually 75% of critical. Then you iterate the mill diameter using a Morrell C-model or equation to get the RPM that corresponds to 75% for that mill diameter.
