19/11/2019Fineness The finesse of the material milled by the ball mill is 0.074mm-0.4mm, only except for the two small ball mills that have a wider range of 0.075-0.89mm. However, the rod mill fine grinding fineness is about 0.833-0.147mm. In terms of the fineness of the ground material, the ball mill has a finer handling ability.

The first set (usually three or four numbers) is about the rod length and type. The second set is about the line, and the third refers to the ideal lure weight. The three sets of numbers are usually in that order, but not always. Before we go further, make sure you can identify the three different sets of numbers when looking at a rod.
