Effect of ball mill grinding parameters of hydrated

2013-5-1  Operational grinding parameters have marginal effect on fineness of particle. Real surface area enhancement did not occur on the external surfaces, but in the inner surfaces due to lime hydration process conditions. The ball mill load and speed are the most important parameters rather than material charged volume. The undersize percentages of 297, 53 and 10 μm are quality control checkpoints for
