A Bond Ball Mill Work Index test is a standard test for determining the ball mill work index of a sample of ore It was developed by Fred Bond in 1952 and modified in 1961 (JKMRC CO, 2006) This index is widely used in the mineral industry for comparing the resistance of different materials to ball milling, for estimating the energy required.
The Bond ball mill work index is one of the most commonly used grindability tests in mining, and is often referred to as the Bond work index. The test is a 'locked-cycle' test where ground product is removed from test cycles and replaced by fresh feed. The test much achieve a steady-state before completion.
Price Of Index Bond Ball Mill Page Bond Ball Mill. The bond ball mill grindability test measures hardness as an index, regardless of the feed size, so it does not give credit for the additional fines.Therefore, the index itself is ignored in the analysis and the results are assessed in terms of throughput rate or specific energy requirement.The total power for the hpgr system can be compared.

Bond Index Ball Mill / Rod Mill BT 100 XL RETSCH. 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 closed grinding circuit in a ball or rod mill.
Bond Ball Mill. This 12" x 12" ball mill is universally used for grindability testing and determination of the Bond Work Index. Mill comes complete with ball charge, and .
Ball mill design requires a Bond work index, BWi, for ball mills at the correct passing size; SAG mill design requires an appropriate SAG test, for example, SPI (Chapter 5). Flotation design needs a valid measure of kinetics for each sample, including the maximum attainable recovery and rate constants for each mineral ( Chapter 12 ).
Bond Work Index - an overview ScienceDirect Topics. The ball mill index oratory test is conducted by grinding an ore sample prepared to 100% passing 3.36 mm (6 mesh) to product size in the range of 45-150 µm (325-100 mesh), thus determining the ball mill index (Wi B or BWi).

Safety is a prime consideration for all Alsto equipment and the Bond Index Ball Mill is supplied equipped with acoustic enclosure. The ball mill is designed to accept a ball charge in accordance with F. C Bond's standard. This ball charge consists of 286 balls as follows: 44 x 35mm balls; 67 x 30mm balls; 10 x 25.4mm balls, 71 x 19.05mm balls and
The optimum number of grinding balls is 285. However, the ball diameters vary due to wear. Therefore, the total ball number should be adjusted from time to time to ensure a total mass of 20.125 grams. The grinding jar of the Bond Index Ball Mill measures 12″ x 12″ and has well-rounded corners. Module Rod Mill

This ball charge consists of 286 balls as follows: 44 x 35mm balls; 67 x 30mm balls; 10 x 25.4mm balls, 71 x 19.05mm balls and; 94 x 12.7mm balls; Fully automated version of the Bond Index Ball Mill is also available on request.
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 ...
