Its high energy utilization ensures that the ore is ground to optimal fineness for further processing, resulting in higher yields and better quality lithium products. ... Lithium ore ball mill. In the grinding and grading stage ...
The ball mill circuit consists of two stages of grinding. The primary ball mill reduces the size of the HPGR product stream which is then sized by hydro cyclone. The ball mills are rubber lined and relines occur every year. The primary mill is 9.0 MW and uses 50mm steel balls, and the secondary mill is 6.2 MW and uses 20 mm steel balls.
Modern iron ore pelletizing process operations may be divid-ed into two main process sections: feedstock preparation and agglomeration processes. In most plants, the required particle size distribution (PSD) is obtained through the wet ball mill circuit. In the past few years, natural resource awareness be-
