Methods of sampling and test for carbonaceous materials used in aluminium manufacture - Electrode coke - Determination of grain stability of calcined coke using a laboratory vibration mill
Calcined coke with poor mechanical strength may be-come degraded during mixing. Poor grain stability will affect the grain size and may result in poor quality of baked blocks.
This International Standard describes a laboratory vi-bration mill method for the determination of the grain stability of calcined coke for the manufacture of car-bon products used in the manufacture of aluminium.
