## Technical Performance and Application of Ball Mill and Rod

Unlike the ball mill, the grinding medium in the rod mill is a steel rod, so the working characteristics are significantly different from those of the ball mill Since the steel balls are in point contact, the steel rods are in line contact When the steel rods are sandwiched between the steel rods, the coarse particles are first broken, and the fine particles are protected to some extent On

## Mill (grinding) Wikipedia

Rod mill A rotating drum Rod mills are less common than ball mills for grinding minerals The rods used in the mill, usually a highcarbon steel, can vary in both the length and the diameter However, the smaller the rods, the larger is the total surface area and hence, the greater the grinding efficiency Autogenous mill Autogenous or autogenic mills are socalled due to the selfgrinding
