    The constant K 2 is also dependent on ore type and ranged from 1.4 to 1.5. A regression of Magdalinovic’s data including the feed 80% passing size gives an average value of 1.485 for K 2.If we extend this relationship to any sample of screened material then this gives an approximate estimate of the 80% passing size as 67.3% of the top size.

    Jan 01, 2009· 1. Introduction. A Bond Ball Mill Work Index test is a standard test for determining the ball mill index of a sample of ore. It was developed by Fred Bond in 1952 and modified in 1961 (JKMRC CO., 2006).This index is widely used in the mineral industry for comparing the resistance of different materials to ball milling, for estimating the energy required for grinding, and for ball mill

  • Correlation Between Work Index and Mechanical Properties

    Abstract The crushing energy for applications in the mineral processing industry is usually determined by an empirical bond index, regardless of the mechanical properties of a rock. Although several attempts have been made to obtain the comminution energy based on theoretical approaches, it would be beneficial to examine this relation based on a physical concept.
