### Overflow VS Grate Discharge Ball or Mill - Why Retrofit

In order to get a steep particle size distribution curve, the mill is used in closed circuit with some kind of classifier and the coarse particles-known as classifier underflow-are recycled. Furthermore, it should be observed that a grate discharge ball mill converts about 20% more energy than an overflow discharge mill with the same shell dimensions.

### 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).

For fine regrinding in open circuit, the ratio ranges from 1.3:1 to 1.5:1. Some ball mills are separated in to compartments by grates. The grates hold back particles above a certain size for additional grinding. The compartments could contain different ball sizes. Large to small from the feed end. Some mills have a conical section.

### Closed circuit ball mill – Basics revisited - ScienceDirect

1. Introduction. Over the years, ball mill circuits closed with cyclones have become an industry standard, and since the early days, it has been recognised that classification efficiency and circulating load both have a major effect on the efficiency of closed circuit grinding (i.e. its capacity to produce the desired final product).

### Comparison of open and closed circuit HPGR application on ...

Within this study effect of open and closed circuit HPGR applications on dry grinding circuit performance was examined. For this purpose sampling studies around three different cement grinding circuit were completed. In the first study, a circuit including open circuit HPGR, ball mill and air separator was sampled and chosen as the basic condition.
