The Bond Ball Mill Work index (BBWi) is the industry standard procedure for assessing the grindability of ores. The test involves conducting a locked-cycle grinding test using ond’s standard mill design. The locked-cycle test enables a batch process to emulate the grinding behaviour of a continuous mill with a 250% recirculating load.

3- STANDARD BOND TESTS The Bond's 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
SMC Data Processing. The results from conducting the SMC Test are used to determine the drop-weight index (DWi) which is a measure of the strength of the rock as well as the comminution indices Mia, Mih and Mic. In conjunction with the Bond ball mill work index they can be used to accurately predict the overall specific energy requirements of
The test work will entail industry standard tests such as the Bond Rod Mill Work Index, Bond Ball Mill Work Index, JK/DWi tests and then some specific batch mill tests. The results of the test work will then be used to determine the parameters required for Simulation. The simulation can then be used to size an entire comminution circuit
Dec 18, 2013 where W is the specific grinding energy (kWh/t), W i is the Bond ball mill work index (kWh/t), F80 is the feed 80 pct passing size (μm), and P80 is the product 80 pct passing size (μm). It can be seen that in the regime in which the Bond equation is valid, energy use increases exponentially as product size decreases with constant feed size
The SAG mill pinion energy, W SDT (kWh/t) and SAG discharge Bond ball mill work index, S d-BWI (kWh/t), are then used to calculate the total energy to grind the ore from 80% passing 152 mm to 80% passing the client specified final product size P 80.This information, along with the ore specific gravity, is used to calculate necessary mill sizes and motor power in industrial applications.

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)
In conjunction with the Bond ball mill work index they can be used to accurately predict the overall specific energy requirements of circuits containing: • AG and SAG mills. • Ball mills • Rod mills • Crushers • High Pressure Grinding Rolls (HPGR)
Bond Work Index - an overview ScienceDirect Topics. The ball mill work index laboratory 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 m (325-100 mesh), thus determining the ball mill work index (Wi B or BWi).

The Bond Ball Mill Grindability Test is a locked-cycle laboratory grinding test. It provides the Bond Ball Mill Work Index which expresses the resistance of a material to ball milling. This Index is widely used in the mineral industry for comparing the resistance of different materials to ball milling, for estimating the energy required for grinding, and for ball mill scale-up.
The Bond ball mill grindability test is run in a laboratory until a circulating load of 250% is developed. It provides the Bond Ball Mill Work Index which expresses the resistance of material to
Essa Bond Test-Work Equipment. Internationally accepted mineral metallurgical standard test procedures to determine the physical properties of ores include the Bond ball mill work index and the Bond rod mill work index. These are empirical indices determined by close circuit grindability tests developed by F.C.Bond in the mid 1930’s.
