Rod Mill - Ball Mill - Cement Milll AGICO Cement

The working principle of rod mill is that the main motor is connected with the pinion through a reducer to drive the large gear ring, thus rotating the cylinder. There are some steel rods in the machine chamber. When the cylinder rotates, the centrifugal force produced by the rotating brings the steel rod to a certain height and then falls down. This kind of impact force will have a grinding ...

Ball Mills - Mineral Processing Metallurgy

The basic principle for rod grinding is reduction by line contact between rods extending the full length of the mill, resulting in selective grinding carried out on the largest particle sizes. This results in a minimum production of extreme fines or slimes and more effective grinding work as compared with a ball mill. One stage rod mill grinding is therefore suitable for preparation of feed to ...

What is a Rod Mill? (with picture)

A rod mill is an ore grinding mechanism that uses a number of loose steel rods within a rotating drum to provide its attrition or grinding action. An ore charge is added to the drum, and as it rotates, friction between the tumbling rods breaks the ore down into finer particles. Although similar in operation, a rod mill is often more effective than a ball mill as it requires lower rotational ...
