Many customers have some questions before buy rod ball or ball mill. Sometimes after signed the contract or bought the steel ball, we found that client did not want ball mill but rod mill.

So, Hongji Mine Machinery explains how to choose rod mill or ball mill. Rod mill and ball mill, although the structure is substantially the same, but there are 3 differences:

Rod mill process characteristic is the finished material size more uniform, containing less coarse particles and mineral mud and over crusher more less.

Ball mill process characteristic is high production capacity,strong adaptability for materials,saving energy and the finished materials more fine.
