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 ...

crushing and grinding; and F80 and P80 are the 80% passing size of the feed and the product ( m), respectively. Bond developed a standard laboratory test for the determination of the work index for ball and rod mills in 1952 and modified it in 1961. The standard Bond ball mill grindability test is a closed circuit dry grinding test with a 250% circulating load. The standard procedural outline ...

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 ...

Neither of these two laws permits an accurate calculation of the energy requirements; a further improvement by [16] put p = −3/2 in equation 2 gave rise to: (7) (8) where: q = L 1 /L 2. If the reduction ratio is written as C = 5Ei, then: (9) In [16], the terms E i is the work index, and expresses the resistance of the material to crushing and grinding; and is expressed as the amount of ...
