Bond Work Index an overview | ScienceDirect Topics
The Bond work index ( Bond, 1960) is based on Bond’s law, which states that the energy consumed is proportional to the 15 power of particle size rather than the square of Rittinger’s law Accordingly, the energy consumed in reducing the particle size from x F to x p (both measured as 80% undersize) is given bycrusher Tertiary crushing is usually performed using cone crushers or other types of impactor crushers Oversize material from the top deck of the sizing screen is fed to the tertiary crusher The tertiary crusher output, which is typically about 050 to 25 centimeters (3/16th to 1 inch), is returned to the sizing screen11192 Crushed Stone Processing and Pulverized Mineral Processing
