Bond Work Index For An Ultrafine Mill We are a large-scale manufacturer specializing in producing various mining machines including different types of sand and gravel equipment, milling equipment, mineral processing equipment and building materials equipment
The measured BW i was 14.0 and 6.6 kWh/t for the medium/hard and soft ore, respectively, at a closing screen size of 106 μm compared with the simulated values of 13.2 and 5.6 kWh/t. The ability to simulate the Bond work index test also allows examination of truncated ball mill feed size distributions on
This Table of Ball Mill Bond Work Index of Minerals is a summary as tested on ‘around the world sample’. You can find the SG of each mineral samples on the other table.
Bond Work Index Formula-EquationThe basic work index equation is:W = 10 Wi/√P 10 Wi/√F(Size Distribution and Exposure RatioEquations For Work Index Variations CS Series Cone Crusher High quality, Stable performance, Reliable operation As the second
bond ball mill work index customer case The bond work index is a measure of ore resistance to crushing and grinding and is determined using the bond grindability test its value constitutes ore characteristic and is used for industrial comminution plants designing determining the bond work index value is quite complicated, timeconsuming and requires trained operating personnel and therefore is
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
grinding cycles. The Bond Work Index is calculated using the formula: 𝑖=1,1 44,5 𝑃𝑐 0,23𝐺,82(10 √𝑃80 −10 √𝐹80) (1) where W i Bond work index (kWh/t) P c test sieve mesh size (µm) G weight of the test sieve fresh undersize per mill revolution (g/rev) F 80 P
1/1/2017 The Bond work index is a measure of ore resistance to crushing and grinding and is determined using the Bond grindability test. Its value constitutes ore characteristic and is
The Bond work index (Bond, 1960) is based on Bond's law, which states that the energy consumed is proportional to the 1.5 power of particle size rather than the square of Rittinger's law. Accordingly, the energy consumed in reducing the particle size from x F to x p (both measured as 80% undersize) is given .
