The best correlation was found with grindability bulk modulus (Kd ). The dynamic bulk modulus is also called the modulus of rigidity. It takes into account conditions of porosity and discontinuity, such as joints. For this reason, finding a correlation between the dynamic bulk modulus and grindability is realistic. The grindability and work index values were calculated by using the dynamic ...
