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.Sep 12, 2019 However, this requires a significant amount of ore samples, a lot of labor and the pilot plants. Fred Bond published an article in 1961, which, described the procedure for testing ores for a Bond Ball Index. This parameter is still one of the most demanded tools in the design, evaluation and optimization of ball grinding plants around the world.
Involve grinding). With Lloyd's ball milling book having sold over 2000 copies, there are probably over 1000 home built ball mills operating in just America alone. This article borrows from Lloyd's research, which was obtained from the commercial ball milling industry, and explains some of the key design criteria for making your own ball mill.Bond work index value of these components mixtures is greater than the Bond work in dex of harder components, clinker. Oner (2000) have conducted a research of clinker and blast furnace slag mixture Bond Work Index in different mass propor tions. He found out that these values are always lower than the Bond Index obtained.
This high pressure also creates a large amount of fines and causes the formation of microcracks in the larger particles, lowering the Bond work index of the ore and reducing the ball mill.Introduction. The Bond Work Index for Ball Mill is a special equipment for testing Bond ball mill work index. Simple lab test can choose ball mill by power method or judge the effects of material properties change to the ball milling process or the operation condition of crusher by using this equipment.
