To increase efficiency ...
— Relation of Bond ball mill work index and rod mill work index. The Bond rod mill and ball mill work indices are the most similar in size classes, both being fed material crushed to "relatively fine" sizes. Both test are also locked-cycle tumbling tests where the charge of ore in the mill is brought to a steady state over the duration of a test.
Overflow rod mill is the most common mining rod mill model. The product particle size is finer than the other two rod mills, generally used to grind the crushed products, and then provide it to the ball mill for further grinding. End peripheral ore discharge rod mill. The discharge end of this mining rod mill is located at the end of the barrel.
— The feed enters one end of the ball mill, and discharges out the other end. Ball mills vary greatly in size, from large industrial ball mills measuring more than 25 ft. in diameter to small mills used for sample preparation in laboratories. Rod mills are similar to ball mills and use metal rods as the grinding media. Pebble mills use rock ...
