Rod Mills are particularly useful if you run a low tonnage operation and are looking for coarse product. Our Rod Mills are available in multiple diameters to fit the needs of your operation. Grinding primarily by attrition Rod Mills require comparatively low levels of power to operate.
Our products sell well all over the world, and have advanced technology in the field of crushing sand grinding powder.
Please find below two calculators for siing mills using the Bond and Rowland methods Ball mill siing Calculator for ball mills in a single stage circuit. Rod ball mill siing Calculator for rod mills as first stage of the circuit and ball mills as second stage of the circuit.

The siing of ball mills and ball milling circuits from laboratory grinding tests is largely a question of applying empirical equations or factors based on accumulated experience. Different manufacturers use different methods and it is difficult to check the validity of the siing estimates when estimates from different sources are widely divergent. It is especially difficult to teach mill

Maximum rod length is limited to about 6.1 m 20 ft. This in turn limits the length diameter and capacity of rod mills. The heavier rods acting upon the lifters and liners result in greater wear on the mill liners. Rod mills normally carry 35 to 65 rod charge by volume.
