A New Approach to the Calculation of Work Index and the ,The same mill is used for the semi continuous grinding tests which is similar to the Bond test but with the exist- ing mill of known power. After time the mill product is t wet screened at a predetermined screen size. From the weight difference of the over size before and after grind- ing one calculates the grinding rate. The over size (cir- culating load) is then dried (105˚C), returned to

[PDF] The Effects of Blasting on Crushing and ,The ore passes through primary and secondary crushing and grinding. The final product is 80% passing 270 mesh. Bond has published a Wi for taconite of 14.87 (1961). This value is used in these base case calculations. Table 1 shows the feed and product size, the calculated total energy input, and the energy cost for each unit operation. The explosive cost is based on the powder factor of 0.33

Calculation of energy required for grinding in ,Calculation of energy required for grinding in a ball mill. Int. J. Miner. Process., 25: 41-46. The Bond work index, Wi, as an indicator of the grindability of materials is not a material constant but rather it changes with change of size of the grinding product. Therefore, in practice we can expect some difficulties and errors when the energy consumption is determined according to this

QUICK METHOD FOR BOND WORK INDEXAPPROXIMATE VALUE ,Abstract: 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, time-consuming and requires trained operating personnel and therefore is subjected to errors. A

Fred Chester Bond - Wikipedia,Bond Work Index. In the 1930s through early 1950s, Bond developed a new theory of comminution that introduced an index, called the 'Bond Work Index', which relates power consumption in crushing and grinding to the feed and product size distribution. His theory and index were introduced in a widely cited 1952 journal article. Bond called his theory the "third theory of comminution", counting
