Even though they may only play a small part of the process, dewatering bucket wheels are an essential part of the construction of many buildings. This is because they ensure that certain construction materials are up to specific standards. This is incredibly important as, if they’re not up to standard, then this could affect the overall quality of the entire building.
Because of that, it’s incredibly important that dewatering is done well and that can only be done with high quality dewatering bucket wheels. Despite its importance, there are many things that most people might not know about them, especially in regard to how they work.
1. How Do They Function?
Either a mixture of substances or just one substance at a time – depending on what’s needed – is first fed into an impact chamber, which is protected internally against wear and tear. After this, it’s then fed into the bucket wheel in order to be dewatered.
The substance is normally fed into the wheel through the use of a suction dredger, compressed-air dredger, floating grab or a preparation plant. Any substances are put into the bucket wheel tub and then excavated by the wheel. This is done through the use of cups with special plastic screens of varying widths.
A natural vacuum is created through the use of extended suction chambers; this helps to keep the dewatering degree to a minimum. On the inside of the tub, there are also a few adjustable overflow weirs that can define how fine or rough the substance in question is.
There is also a number of different speeds at which the bucket wheel can turn at, depending on how fine you want the sand or other substance to be. Having said that, they normally stick within the range of 0.5 to 2 revolutions per minute (rpm). Because of this low revolution speed, the bucket wheel ends up using a lot less power than you might expect.
Having said that, the exact amount of power that it uses depends an awful lot on the exact model that you’re using, as well as how much dewatering you’re doing on a daily basis.
2. The Types Of Substances They Work On
Dewatering bucket wheels are chiefly used to dewater or deslurry certain substances, which is how they got their name. Having said that, there are only a limited amount of substances that they can be used on. This may come as a surprise to some people, as many might wrongly believe that they can be used on several different substances.
It’s worth knowing what exactly the can dewater and deslurry. They work on the majority of substances that are used in construction, aside from concrete. Typically, they’re used on sand, gravel, calcium carbonate, silica and feldspar. This would encompass the majority of the substances that would be needed for the construction of a building.
Having said that, while they’re not the only substances used in construction, generally speaking they’re the only ones that would need to be dewatered or deslurried.
3. They’re Incredibly Adjustable
Based on the above, many people think that it’s just as simple as watered substances go in, and then dewatered substances come out with almost no input from a worker. However, that couldn’t be further from the truth as dewatering bucket wheels are incredibly adjustable from a side panel.
This panel allows people to adjust a vast number of aspects of the process. For example, one of the biggest things that can be adjusted is the material split. This affects how much water is actually removed from the sand or other substance. This can be incredibly important depending on what exactly the substance in question will be used for.
Another major aspect that can be adjusted is the water flow, which can change depending on whether you’re washing the substance or dewatering it. In either case, the substance may end up needing to be dewatered. Because of that, there will be a massive change in water flow; for example, a certain amount of water being put in versus a certain percentage of water being taken out.
In the dewatering process, removing a certain percentage of water from the substance is a necessity as for certain uses, there can be a maximum limit on how much water can be used in the substance.
