### QUICK METHOD FOR BOND WORK INDEXAPPROXIMATE VALUE

between grinding parameters and the Bond equation by the standard Bond test does not exceed 2.6%. The aim of this study was to develop a new method for assessing the Bond work index in a ball mill (BBWI), which is Andesite and limestone samples were prepared by crushing in a laboratory jaw crusher and roll crusher in a closed

Bond Tests | Mining | SGSThe test determines the Bond Impact Work Index which is used with Bond's Third Theory of Comminution to calculate net power requirements when sizing crushers*. It is also used to determine the required open-side settings (jaw crushers and gyratory crushers) or closed-side settings (cone crushers) for a given product size.

The SMC and Bond ball work index experiments as well as the Morrell model indicated that the order of the speciﬁc energy consumption of comminution was "Jaw crusher + HPGR mill + ball mill" < "Jaw crusher + ball mill"< "SAG mill + ball mill". Keywords: standard drop weigh test; SMC test; Bond ball work index test; JKSimMet; Morrell 1.

Size Reduction and Energy Requirement - · This equation reverts to the Bond equation (Equation ) by taking the value of B as 12 and integrating; thus, (3.7) E = k 1 P 6 12 − 1 F 6 12 which in effect is the Bond equation. Bond's original work on establishing the energy for size reduction was established in a 2.44 m (8 foot) internal diameter wet grinding overflow type ball mill.Comparison between bond crushing energy and fracture the Bond index. There is considerable difference between Bond crushing energy and work done by the jaw crusher for rocks. It appears that the Bond approach is not a suitable method for predicting single particle fracture energy done by the crusher. To verify the results obtained from DEM models, the fracture behaviour

### 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. 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 USING THE SMC TEST® TO PREDICT COMMINUTION CIRCUIT = Coarse ore work index and is provided directly by SMC Test ® For fine particle grinding equation 1 is written as: f x f x 3. 2 b ib. 4 3 W M x x. 2 (5) where . x. 2 = 750 microns . x 3 = P 80 of final grind in microns .
