2009826the pilot mill is also equipped with a sensor measuring the ball and pulp toe and shoulder angles see figure 3. these data are then used to calculate the total pulp and ball charge angle see graph 5. graph 5 clearly illustrates how the ball charge stays quite compact till about 73 solids as the total media angle does not change.
Click on it20151216rod mill grindability tests. as discussed earlier in this paper, it is important in this case to match the reduction size of the test to that desired from the industrial mill. as such, primary ball mills should be designed with the rod mill work index, and singlestage ball mills should be with both the rod mill and ball mill indices.
Click on itThe ball charge of a sag mill is about 29 to 30. by friction and influence of tumbling balls inside rotating cylinder grinds the raw material to the required fineness. the internal machinery of ball mill grinds the raw material into the powderlike material, and if extreme fineness and refinery are required then rotation go on continue.
Click on itAs in ball mills, the power draft of a rod mill is the product of capacity and work index, which is the energy required to break a mineral of a given size to the required size. the mill power is also increased by increasing the rod charge and the mill speed, while the mill power and capacity are both increased with increasing mill length.
