Rod grinding process is an ore grinding method which uses a long round metal rod as the grinding medium in a mill to smash the ore. In the rod grinding process, when the rod medium moves in the barrel of the ore mill, there is a line contact between them. A sieve structure similar to a rod is formed between the rod media, which serves …
