How SAG Mills Work Their Magic

Introduction:

The mining industry is certainly far from going out of fashion considering just how useful it is. With a plethora of purposes of its own, it has to utilize brute strength and undeniable resistance most of the time to get the job done. This means that they need the right sort of tools that can help them achieve that job and do it with the perfect amount of precision. It is not always easy to find equipment with the required level of strength to be of use in the mining industry but new and improved tools are now being made use of. There are plenty of those such as apron feeders, excavators, and loaders among a whole lot more. One of them happens to be SAG mills.

What Are SAG Mills:

If you are wondering what the term ‘SAG’ stands for it is actually an abbreviation for semi-autogenous grinding. To sum up, what it really does, the main force is aimed at grinding. It is used in the primary or initial stages for the main part, as that is where their purpose lies. It is not just ball mills that make use of grinding balls to get the entire job done but also SAG mills as well. However, that does not make them similar in the least, as ball mills happen to have a longer length and a shorter diameter when they are compared with SAG mills. These balls even use a charge of up to 8% to even 21% to get the work done.

How Do SAG Mills Work:

The main purpose of SAG mills is to handle the grinding aspect by either preparing it so the material can proceed to be further ground or come up with a finished product after going through this stage. If you think crushing and screening can be a good alternative for this mill you are wrong for sure. It is actually worth two or three stages of that alternative as it achieves the same goal with much less hassle and greater efficiency. Modern mineral processing plants make use of it due to this very reason as it makes the process far less complex. Lifting plates are line up on the inside of the mill, as something would definitely be required to help lift the material. This material is then dumped onto the ore charge.

Range Of Useful Applications:

SAG mills are actually pretty handy if used the right way. Since they come in all kinds of sizes people can make use of them according to their varying needs. Some may need it for large-scale grinding for which the sturdier versions should be made use of. Others may turn towards the smaller versions that can save some of their costs. This also goes on to benefit the owners as the maintenance costs will not be that high because it is not set up in a traditional way. It can provide a plethora of benefits while also saving a couple of bucks. Can it get any more ideal than that?

Admirable Features:

There are numerous features belonging to SAG mills that truly make them worth a shot especially if you are into the mining industry. As it is used for grinding purposes and is bound to encounter some pretty hard material, SAG mill is also ensured to have a good amount of hardness. One of its better features is that it is resistant to corrosion which of course contributes to the fact that it will continue to function for a longer period of time. Not only that, but it also has a resistance to abrasion that simply adds to its usefulness. As there may be times when it is used in wet grinding conditions special care is taken to ensure that it also has high impact toughness.

Conclusion:

SAG mills are known to be extremely useful especially for people who need it for mining. If you want the material to be reduced to a much smaller and crushed size a SAG mill is what you need to get the job done.
