Bond Index Ball Mill Rod Mill BT 100 XL - RETSCH The Rod Mill Work Index RWI is used for particle size determination in a size range from 25 mm down to 2.1 mm whereas Ball Mill Work Index BWI is used for the range from 2.1 mm down to 100 amp 181m.
Ore hardness, like many other intrinsic ore properties, varies across a deposit, hence will also vary in ore delivered to the mill throughout the life of mine. There are a variety of laboratory-scale tests which assess comminution breakage properties, such as Bond Ball Mill Work Index BWi, JK Drop Weight Index DWi and SMC Test . The test ...

A systematic investigation was carried out to predict Bonds work index using simple field measurable properties of rocks. Tests were conducted on Basalt, Slate and Granite using a laboratory scale ball mill and rock properties namely density, Protodyakonovs strength index and rebound hardness number were determined.

The ability to simulate the Bond work index test also allows examination of truncated ball mill feed size distributions on the work index. For grinding circuits where the feed to a ball mill is sent directly to the classifier and the cyclone underflow feeds the ball mill see Figure 3.10, a question arises as to whether this practice will alter the ball mill work index BW i of the material ...
3- STANDARD BOND TESTS The Bonds standard ball mill is used to determine the work index value of differ ent samples. The Bond work index is defined as the kilowatt-hours per short ton required to break from infinite size to a product size of 80 passing 100 m. If the breakage
the rod mill and the ball mill. The simplified test method described in this paper is an alternative procedure to the ball mill grindability test. The work index is computed using the following empirical equation revised by Bond in 1960, where the sieve opening at which the test is made, microns 358 2
1 Introduction Finding the bond work index of an ore type is crucial to determining the grinding energy required during comminution in a ball mill. The bond work index is a constant characteristic related to the hardness of a specific ore type. Bond work index is one of three different approaches that can be used to calculate the work index of an ore.
The Work Index is used when determining the size of the mill and grinding power required to produce the required ore throughput in a ball mill. 2. Procedure 2.1. Bond Ball Mill Grindability The sample was crushed to 100 passing 6 mesh 3.35mm, from this a 700 cc volume was measured and weighed to be used as feed for the Bond Mill.
