Machines play an important role in sorting and classifying different materials and can be categorized into two major types: rotary and vibrating screens. Despite the fact that they may first appear to be one and the same, a critical difference exists between these two. These machines are built by a Shanghai company called Shanghai Yuanyuda. Now it is time to analyze on which grounds rotary screen and vibrating screen are grouped or positioned! 

What is Rotary Screens and what are related differences and similarities with Vibrating Screens?

The other difference between rotary and vibrating screens is how they operate in this aspect. Rotary screens rotate in circular fashion (similar to a Ferris wheel) to angle the materials down the screen. Vibrating screens, on the other side, move back and forth, like something is jumping up and down. The amplitude of the shaking motion of Shanghai Yuanyuda түйіршіктеу жабдықтары converts the material surface into a sort of conveyor. This makes the rotary screen to be more advantageous for large volumes of materials and where a lot of material needs to be categorized. On the other hand, vibrating screens are preferable when working with small amount of material and most appropriate for classification with negligible tolerance. 

Rotary Vs Vibrating Classifiers

Having discussed above the working mechanism of the rotary classifiers and vibrating classifiers separated, let us examine the following below to know the distinctions between them. Rotary classifiers are generally preferred with dry products, for example sand or dust. This is what makes them ideal for industries (for instance construction or mining) which require a faster sorting of bulk dry materials. However, vibrating classifiers are used with wet materials which include mud or slurry more information about vibrating classifiers is mentioned below. Still, sieves are perfect when it comes to sorting materials since their mechanism of action is based on shaking.

A fourth difference is still in the large size of the industry and relatively low costs. Rotary classifiers are largely larger, and significantly costlier in comparison to the vibrating classifiers.  But, where very high degree of accuracy of sorting is called for, then it is the vibrating classifiers that gain prominence. It has added that they are more accurate of which is very important in some segments with the help of the food segment. In food processing, materials must be classified to very specific sizes for better safety and food quality. Therefore, for the heavy-duty work, Shanghai Yuanyuda экструдер-жабдық are the most suitable in this regard while more delicate work require vacuum classifiers and vibrating classifiers. 

There are advantages and disadvantages of using rotary and vibrating screens in industries as will be discussed below.

Next we will look at the advantages and disadvantages of each type of screen. The rotary screens possess the following benefits: It also means they are also capable of handling vast amount of material at once, thus appropriate for high volume work. They are also usually stronger compared to vibrating screens and, in the appropriate cases, can also have longer service life. However, the downside associated with them they are usually a bit more expensive and they are more delicate thus demanding more care.

On the other hand, vibrating screens promise to enhance specific values as illustrated in the table below; These are also generally cheaper and require fewer maintenance compared with rotary screens which make then efficient to use. However, it might not be as robust as the rotary screens, which will last longer in use might wear out much earlier. It operates still very effectively regardless of the amount of the material used, which is why it is used in applications that call for precision.

The above mentioned feeds are transported through rotary and vibrating classifiers for subsequent operations.

Now it’s time to look at each of these classifiers and how it is computed internally. Functional Operating Behavior of Rotary Classifiers: Turning the screen in a manner makes the materials to fall through some small holes. The larger material stays on the top and it is forced out of the end of the screen at some time, whereas; the fine material take time to move through the screen. Especially, this technique is most effective when used for the sorting operation.

However, vibrating classifiers use an approach where the screen vibrates. The shaking motion moves those materials on the screen and sorts them by their sizes. And, the holes in the screen are instrumental to this procedure. Indeed, the holes define the size of the material that can go through the holes at all. Then the material is sorted more precisely, and this is large for a lot of industries, if the holes are smaller. 

The Classifying Screens: A Guide to Getting the Right One

When choosing this classifying screen it would be important to consider some of the following. Now to directly apply this type of concept, first think about the type of objects or things that you want to organize. Is it dry or wet? Second, consider the amount of information to sort out” It is, a lot I think or is it a little? Last but not least, think about what level of granularity you need your sorting to be. Basically, a Shanghai Yuanyuda ұнтақтау жабдықтары may be best and the most practical bearing in mind that am working with large volume of dry material. However, if you require precise sorting of moist products, then a vibrating classifier will suffice your requirement more appropriately.

In any case, as with rotary classifiers and vibrating classifiers, there may be some resemblance which must be understood that both of them are based on the different principles and that creates a difference. To get an appreciation of these differences it will enable you to make the right decision as to which type of screen suits you best. Shanghai Yuanyuda specialize in rotary & vibrating classifiers for separating and classifying of material.
