### How to Measure Grinding Efficiency

The first two Grinding Efficiency Measurement examples are given to show how to calculate Wio and Wioc for single stage ball mills. Figure 1. The first example is a comparison of two parallel mills from a daily operating report. Mill size 5.03m x 6.1m (16.5′ x 20′ with a ID of 16′). This example shows that Mill 2 is slightly more efficient than Mill 1 even though it has a higher power .

### Ball Mill Design/Power Calculation

Ball Mill Power Calculation Example #1. A wet grinding ball mill in closed circuit is to be fed 100 TPH of a material with a work index of 15 and a size distribution of 80% passing ¼ inch (6350 microns). The required product size distribution is to be 80% passing 100 mesh (149 microns).

### Quantifying Grinding Efficiency - Grinding

When calculating rod mill power for a rod mill-ball mill circuit, do not allow for improvement in the ball mill performance. If the rod mill feed is produced with open circuit crushing, apply a 1.2 inefficiency factor to the power calculated for the rod milling stage only.

### Formula Of Crushing Efficiency Crusher Usa

Crusher Efficiency Calculations. A jaw crusher, like 2036 in the Jaw Crusher Table here above, would be able to take the maximum 12 in. size quarry stone but it would not have the required 70 tph capacity needed. To have the needed capacity a jaw crusher like the 2042 or 2436 sizes will have to be selected overloading the secondary crusher.

### The energy efficiency of ball milling in comminution

Earlier work by Fuerstenau and Kapur on the comminution of quartz in a single-particle roll mill and in a dry ball mill showed the energy efficiency of ball mill comminution to be 22%. Thus, as a mechanical device for producing fine particles, the ball mill is reasonably efficient energetically.
