Effect of Balls Hardness on Rate of Grinding. Tests by Coghill and Devaney show that the hardness of the balls has some effect upon the rate of grinding in mill. These results are plotted in Fig. and it is seen that, both for dolomite and chert, there is an increase in the rate of grinding with increasing hardness of ball.
Operating with consistent reliability and high availability while also achieving a good quality product at the end of the process is a challenge.

In some cases it was also indicated that the shape of particles from HPGR would be different; more angular as compared to ball mill products (Fig. 2) (Bleifuss, 1997).This, together with a high proportion of fines would allow a HPGR product to be suitable for pelletizing at a lower Blaine value from a presumed better packing and density in the generated pellets.
Just as a heart must never stop beating, so a rotary kiln must never stop turning. Which is why our kilns whether the twopier Pyrorapid® or a classic threepier kiln are engineered to keep rotating, even in the most challenging of process conditions. So, you can relax with the guarantee of reliable, troublefree operation, 24 hours a day, seven days a week.
