Ball mills and rod mills are both excellent mining machines for grinding ores into fine powders and particles. However there are some advantages to using rod mills rather than ball mills for larger mining projects including greater efficiency, better grinding performance and lower energy costs. Though ball mills are used more often rod mills can be the better option for specific mining ores and larger site projects( Ore Processing Plant For Sale ).
In a ball mill the actual balls in the machine need to cascade in order for the grinding to be accomplished. Because of this more energy is needed to power up a ball press as opposed to a rod press. Rod mills can be operated at lower peripheral speeds resulting in reduced energy costs. Though this difference in power can vary depending on the type of ore you are grinding the consensus is that a rod machine requires less speed to perform the same function as a ball device.
Another key factor in choosing a rod machine over a ball type press is void space. You ideally want as little open space as possible so you have more grinding contact between the rods and the ore. Ball mills need more open space so the balls inside can cascade and grind but this space lessens the contact between metal and ore per surface area. Again, depending on the site project media rods won't necessarily always be the better option but if you are concerned about void space in your grinding process( Ore grinding process for sale ) a rod machine may be the right choice.
If you are working on a mining site dig that is excavating large pieces of rock, coal, copper or other mining media than a rod mill may be a better fit than a ball. Steel rods are more suited to breaking up larger pieces of ore due to the heavier weight of the rods. As well, heavier ore produces more energy per collision which can be better optimized by steel rods rather than balls. If you need to grind mining media down to fine particles than a ball mill is recommended but if the material is large consider a rod mill for the heavy duty grinding.
