Although it was developed nearly 50 years ago, Bond8216s method is still useful for calculating necessary mill sizes and power consumption for ball and rod mills. This paper discusses the basic development of the Bond method, the determination of the efficiency correction factors based on mill dimensions and feed characteristics, and the application of the results to designing grinding circuits.
The development of the ball mill during the twentieth century has been described as the most significant development in the machinery for performing the grinding of ores Lynch and Rowland 2006. A key part of the implementation of ball mills was the development of the ability to predict their performance in the plant based upon grindability data from standardized tests performed in small-diameter laboratory mills.
In 1930, Allis-Chalmers hired Fred Bond to design and build a laboratory for testing ores and grains, for minerals processing and flour milling, and to conduct research for processes for the treatment of ores and grains. Bonds first developments for grinding ores and rocks are now known as the Bond rod milling and ball milling grindability tests. The grindability results from these tests are still reported as net grams produced per revolution of the test mill.8221 Bond carried out two studies using his grindability tests.
1. The first study was to determine if either of the two existing theories of comminution the Rittenger theory or the Kick theory were correct. Bond concluded that neither was correct. He developed a theory that the energy required for comminution was a function of the difference in the square root of the size of theparticles in the feed and in the product of the material being comminuted. This is known as Bonds third theory of comminution.
2. The second study was used to develop a correlation between ball mill operating data and grindability test data. This was based on the Work Index concept. From this concept came two equations a the equation to determine the Work Index from Bond grindability tests, and b the Bond equation, which uses the Work Index to determine the energy needed for grinding.
