I am Zhao Yue from Jinan Houde Steel Ball. The difficulty of grinding materials is almost the same. It mainly depends on the ratio of the ball mill. As long as the ratio is appropriate, there will be no problem. If it is an extra-large ore, Grinding, then steel balls play a grinding role, and large ores can also play a self-grinding role, which is easier than ultra-fine ones. Fine sand may have to be advanced into a rod mill and then into a ball mill for further refinement.

For details, please Baidu Jinan Houde Zhao Yue, find the mobile phone number and contact me
