Abstract :The Bond method is widely used in the design of grinding circuits in an ore preparation plant, sizing of mills, determining power requirements and determining and measuring performance, and for materials considered to be comminution. Its use as a standard is very common in the industry as it provides satisfactory results in all industrial applications. The dynamic method was developed as an alternative to static methods in determining the mechanical properties of materials. There are studies investigating the static and dynamic properties of materials and revealing the relationship between these parameters. There are two different ways to characterize materials to predict performance in industrial scale comminution equipment. The first is to perform standardized tests and assume that these tests best describe the process in comminution equipment. The second is to mimic the process in pilots or large plants to measure variations in performance in different rock types. In this study, the behavior of rocks under dynamic and static conditions was revealed and the relationship between Bond Grindability Test was investigated.
