Bond Work Index - an overview | ScienceDirect Topics
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 …

The grinding jar of the Bond Index Ball Mill measures 12″ x 12″ and has well-rounded corners. The grinding jar for the Bond Index Rod Mill is 12″ x 24″ in size and has a wave-shaped design. At least 15 to 20 kg sample material is required to simulate a …
Bond Work Index Procedure and Method
Cleaning and Storing of Ball Mill Charge after the Bond Work Index Procedure is done: Add about 500 g of silica sand into the mill containing the ball charge. Seal the mill. Rotate for 20 revolutions to clean. Empty the mill charge and sand into the ball try once grinding is complete. Clean out the mill using a brush.
QUICK METHOD FOR BOND WORK INDEXAPPROXIMATE …
According to the Bond standard procedure, the work index is determined by simulating a dry grinding in a closed circuit in the Bond ball mill to achieve 250% circulating load (Bond, 1949, 1952, 1961). The test is performed on a raw material approximately weighing 10 kg, which coarseness is 100% -3.327 mm.

The standard Bond Ball Mill Work Index test procedure is firstly to stage crush the feed to minus 3.35mm, and size a representative sample. The test then involves a series of batch grinds in a standard Bond mill. A Bond mill is 0.305m by 0.305m, with rounded corners, a smooth lining, and runs at 70rpm. The charge consists of 285 balls, weighing a
The Effect of Circulating Load and Test Sieve Size on The ...
In this study, the effect of circulating load (CL) and test sieve size (P,), which are inaccuracies of Bond grindability, on the Bond ball mill grindability (G hg) and work index (W,) are investigated based on four samples of natural amorphous silica. In the experimental studies, the relationships between the Bond work index with circulating load and test sieve size were examined. I …
