尽管… 分离器™ 是a的修改版本吗 水力旋流器，它们的工作方式是不同的. Because of the variance in functionality, they each fit certain applications better.
When trying to decide when to use a 水力旋流器 versus when to use a 分离器™ in a sand plant, 看看它们之间的区别会有所帮助.
何时使用水力旋流器
A 水力旋流器, or commonly called a cyclone, is more widely known and used.
The ideal condition for a cyclone is steady feed in regard to flow rate and solids. The steady flow rate is essential to maintain the desired pressure to make the predictable and repeatable separation.
流量的变化与进口压力有直接关系. 高压会将较小的颗粒送入底流, 而低压会让较大的颗粒进入溢流.
追回罚款
在一些应用中, a 分离器™ can be used almost as effectively as a cyclone in regard to performance, 但 罚款复苏 是否有一个地区更适合飓风.
旋风分离器可以在高于15psi的压力下运行. 当你想捕获尽可能多的材料时，这一点很重要. The higher pressure will increase the centrifugal forces on all the particles through higher angular speeds.
With the higher centrifugal forces spinning smaller particles to the wall of the cyclone, 更细的颗粒将向底流报告.
对于密度一致的饲料
When the solids content in the slurry changes, the effects are seen in the underflow. The size of the apex controls the water split between the underflow and the overflow.
在许多应用中, a secondary goal is to have the least amount of water reporting to the underflow.
While the underflow in a cyclone will not get as high of percent solids as a 分离器™ can achieve, it can still remove the majority of the water when the proper apex is selected.
When the apex is not sized properly to the ratio of solids reporting to the underflow and the amount of solids is too great for the apex to handle, 有两件事会发生:
- 用绳子把底流套住
- 增加细粒旁通到底流
拧成绳状
用绳子把底流套住 happens when the amount of solids is greater than what the apex can handle. This causes the air core to collapse and the cyclone separation is no longer efficient.

In situations where roping can have significant impact on a downstream process, 可能需要安全措施或使用分离器™. The chance to rope on a 分离器™ is drastically reduced due to its oversized apex.
细粒旁路增加
在相反的方向, 当浆料中的固体减少时, 越来越多的水流入地下. This situation will increase the amount fines into the underflow since water will always carry some fine particles no matter what the cut is.
随着水的增加，对底流的细颗粒旁路也会增加.
以获得最佳性能的旋风, the feed percent solids (also called density) should stay relatively constant.
对分级
In situations where sizing is the diving factor in selection, the cyclone should be looked at first. This is especially true if the underflow does not need to be tightly controlled or if it is diluted back down below 50% by weight.
Some of the applications that fall into this scenario include de-sliming before a 分类罐, 螺杆垫圈 逆流分类器(i.e. Hydrosizers™).
Having a cyclone in front of these type of applications can decrease the required sized of the subsequent equipment. This is accomplished by removing the unwanted fines while retaining the desired size fraction.
These applications are similar to using a scalping screen to reduce the load on a sizing screen.
何时使用分离器™
分隔符™ were created to separate water from solids using a syphon to draw the water up through the vortex finder.
This method of creating the updraft to perform the separation limits the upper pressure in the range of 14 to 15 psi.
Applications that need predictable percent solids in the underflow or have large fluctuations in the percent solids in the feed are an ideal fit for the 分隔符™.
The range of feed density can fluctuate between 1% and 25% with little effect on the performance 分离器™.
不需要空气芯, 可以实现更高的底流密度, as the solids will build up in the apex area above the underflow regulator.

使用分离器的主要原因是为了实现干燥的底流. For this reason, a Separator is a good fit to stockpile material without additional equipment.
分离器™卸至库存.
When describing the underflow from a 分离器™, the term “stackable” is most used. Although there is still some water in the underflow, the material will make a pile. This is ideal when the stockpile can be left alone for one or two days to allow additional water to drain away.

当材料不能放置几天时，分离器™和 脱水筛 组合后可生产出“无滴漏”菠菜网最稳定正规平台_最全菠菜网大全.
Drip-free means that if you were to take a handful of the sand and squeezed, no water would come out.

This combination of 分离器™ and 脱水筛 removes the most water, 没有使用过滤器和/或烘干机, 为批量储存或运输准备最终菠菜网最稳定正规平台_最全菠菜网大全.
而旋风可以在组合中使用, 就像罚金回收一样, 它将使材料的细小部分更容易被洗透.
用于去除水分
一些设备，如 消耗细胞当物料中的固体含量得到控制时，该装置的工作效果最佳.
在这种情况下, a 分离器™ will actually remove more moisture than needed by getting the underflow consistently in the range of 75% to 79% solids by weight.
分离器™喂养消耗细胞.
消耗电池将在65%至75%的湿度范围内工作, 但通常更容易加水，以确保正常运行.
While a cyclone can achieve an underflow density of up to 70% solids by weight, 进料中的任何波动都会导致过程中的不一致.
正确的选择
When the feed density is consistent and sizing is the highest process requirement, 水力旋流器是正确的选择. High pressure requirements above 15 psi will automatically shift the choice to a cyclone.
A 分离器™ fits the application when the underflow needs to have as little moisture as possible or when the feed density will have large swings.
