An example problem for a primary rod mill/ball mill grinding circuit was also given. Although the method for determining the proper size and selection of hydrocyclones in …

rod mill work indexes was much more significant and indicated that . ... (ball mill feed) requires the hydrocyclones to be run at lower than . optimal pressures, to maintain sufficient water flow ...

Wire rods are normally drawn down to a specific diameter before being subjected to forging or other forming operations in secondary processing. In several cases, the size of the wire rods before being subjected to these forming operations is to be less than the minimum size of 5.5 mm which can be supplied as rolled from the wire rod mill …

time was employed to indicate if the ball mill is at risk of being overloaded. This method developed by Shi is adopted in this work; the residence time of slurry in the mill is …

When calculating rod mill power for a rod-milling-only application, use an inefficiency factor of 1.4 when the feed is to be prepared with open circuit crushing, and use 1.2 when the feed is to be prepared with closed circuit crushing. The mill diameter, low or high ratio of reduction, and oversize feed factors also must be applied to the ...

The Rod mill has a higher impact force than a Ball mill. This makes the Rod mill better suited to grinding courser or harder ore. In contrast the Ball mill is more effective in producing a finer grind. In most mines, where there is more than one mill grinding the ore, as in the case of our third and fourth schematics. You will find the first ...

After the mill there would be a screen with 1mm opening, fines to spirals, coarse back to the mill. I used rod mills for such a coarse grind, but the handling of the rods is not as easy as if you use balls. So the question came up what a grate discharge ball mill would do here. I never used one. ... We simply had hydrocyclones for ...
