水力旋流器

水力旋流器 were invented in the late 1800s and became widely used in mineral processing because they are relatively inexpensive, 处理高容量, 占用最小的地板空间，没有可移动的部件.

水力旋流器 are commonly used for 脱泥, dewatering and sizing -4mesh (5mm) particles. 它们可用于砂等行业, 聚合, 煤炭, 工业矿产, 硬岩开采和更多. The use of 水力旋流器 in washing and stockpiling is common in the construction aggregate industry. Desliming prior to Classification Tanks and Screw Washers can significantly improve the performance of these devices in high fines situations. 分隔符™ provide consistent density feed to Attrition Cells in 压裂砂.

For mineral applications such as in hard rock and precious metals processing, Cyclones are the most common equipment to control what size of materials exit the comminution (ball milling) circuit. In these applications, it is the fine fraction in the overflow that is the product. 不同的矿石有不同的解离度, 所以水力旋流器有很多不同的配置方式.

替代衬里, 比如聚氨酯和陶瓷, are available for different chemistries (such as where amines are present) and for handling highly abrasive materials. 水力旋流器 can also be made from cast hard metals such as ni-hard and hi-chrome. These designs are often used in processes known as heavy media for 煤炭 and iron ore, etc.

水力旋流器 also find use in pharmaceuticals; agricultural applications, such as sand/manure separation; pulp and paper; potable water and wastewater treatment systems; degritting of spray water; etc.

在聚合应用程序中，典型的恢复时间为2.7 .比重颗粒为+200目(75µm).7 SG; in typical 罚款复苏 applications, 水力旋流器 capture down to 400 mesh (38µm) at 2.7 SG; and in specialty applications, recoveries are possible down to 625 mesh (20µm) at 2.7 SG.

水力旋流器是如何工作的

浆料以指定的压力和体积进入进料口. 与进气道的形状或结构无关的, 浆料在旋转的作用下跟随上筒的下落. Resultant centrifugal forces send coarser material to the outer wall to travel downward and be further accelerated in the conical sections. These coarser fractions then exit through the apex, or spigot, at the bottom of the 水力旋流器. Finer fractions remain rotating with the fluid in the inner core and are removed upward by an air core.

The air core is formed at the spigot/apex as air is drawn in to the 水力旋流器. The vortex finder provides a pathway for the air to exit the body of the 水力旋流器. 当空气流过涡流探测器时, the fluids and finer fractions are dragged along to perform the classification of materials. 空气芯对旋流器的正常运行至关重要. 如果由于过多的固体排放而没有形成空气芯, 被称为套, 旋流器不能有效地对浆料进行分类. 顶点/插口的尺寸适用于固体的预期范围. Significant process changes may require a resizing in the spigot/apex.
