脱水屏幕 are one of the go-to pieces of equipment for removing excess moisture from a final product. 他们 生产无滴漏的材料 that is conveyable, stackable and ready for immediate sale. Additionally, these units are capable of dewatering up to three products on the same screen.
When a 脱水筛 is configured to process more than one product, the screen is divided lengthwise by a divider extension, 或者在三个菠菜网最稳定正规平台_最全菠菜网大全的情况下进行扩展. These divider extensions separate the products being dewatered on the screen so that the coarse material is on one side and the fine material is on the other side. 在三种菠菜网最稳定正规平台_最全菠菜网大全脱水的情况下, an in-between size of material would take up the middle portion.
脱水屏幕 that are used to dewater more than one product also include multiple discharge chutes and a blending gate. The blending gate allows fine material to be combined with the coarse material upon discharge to maximize the specification product.
Say you are dewatering a concrete sand on one side of the screen and a mason sand on the other side of the screen. 如果你的混凝土砂是你的主要赚钱工具, you can blend some of the finer mason sand in with the coarser concrete sand to maximize the amount of salable product while still remaining in spec.

The main reasons to dewater more than one product on the same screen are equipment footprint and cost.
When a single 脱水筛 is used to dewater multiple products, it is doing the job of multiple screens and thus eliminates the need for those other screens. 一个屏幕比两个或多个屏幕占用更少的空间, 因此，脱水系统的占地面积更小.
Purchasing one 脱水筛 instead of several also offers a cost savings, as dewatering multiple products on the same screen lowers capital equipment costs as well as eliminates the structural costs necessary for supporting the additional screen(s).
There are also the indirect cost savings of operation and maintenance of one screen versus multiple screens.
限制
脱水 multiple products on a single screen is often more suited to smaller operations than to larger ones because the cost-savings benefits can be realized more completely and make more of an impact.
然而, there are some limitations with dewatering multiple products on the same 脱水筛. 第一个是吞吐量.
If a 脱水筛 is rated for 400 tons per hour and your operation can make 400 tons per hour of a coarse concrete sand and 200 tons per hour of a fine mason sand, then having two 脱水屏幕 will allow you to maximize throughput of those products. If you wanted to dewater both products on the same screen and the screen is still rated at 400 tons per hour, 总吞吐量将受到影响. The coarse side will have to be derated to accommodate the fine side, so your tons per hour of the coarse sand will be reduced.
Throughput is one of the reasons dewatering multiple products on one screen is more economically beneficial for smaller applications.
The second limitation of dewatering multiple products on the same screen is the risk of screen imbalance. An imbalanced screen can cause undue wear and tear on the screen and increase the potential of component breakage.
分隔扩展有助于平衡屏幕, but getting the proper balance can sometimes be difficult.
The third limitation of dewatering multiple products on the same screen is the risk of cross contamination. 两种菠菜网最稳定正规平台_最全菠菜网大全在同一屏幕上脱水, there is the risk that some of the fines will end up on the coarse side and vice versa. 然而, 这并不总是一个限制, especially if the producer was planning to mix the material via the discharge blending gate anyway.
注意事项
When considering dewatering multiple products on a single machine, also consider this: just because you eliminate a 脱水筛 doesn’t mean you eliminate the number of 水力旋流器 or 泵 系统所需. 如果你在同一屏幕上制作两个菠菜网最稳定正规平台_最全菠菜网大全, you will still need at least two 水力旋流器 (for the coarse side and for the fines side) and two 泵 to feed those 水力旋流器. The cost savings benefit will come only from eliminating the second 脱水筛.
You also want to consider sizing the 脱水筛 slightly larger to achieve the expected level of throughput. 大屏幕比小屏幕更贵.
While there are cost-savings benefits to dewatering multiple products on one 脱水筛, it may not be the right configuration for every application. You’ll want to keep in mind how these cost-savings weigh against decreased throughput and increased component wear.
