水力旋流器是仅利用水和离心力按比例来分选一定粒度的松散物料的重力分选器。水力旋流器由于性能较差,所以在工艺流程中采用它是比较缓慢的,然而它有如下的优点:如结构简单、占地面积小、维护工作量小、不需要重介质和有关回收设备、价格低廉等等。所以,如果用高效处理设备接在其后时,就会使水介旋流器成为一个引人注目的预选设备。采用这种设备的例子,有阿姆赫斯特和第昆斯内拉脱的洗选厂,在那里使用旋流器调整给料(筛出给料中的大块一译者注)到重
Hydrocyclones are gravimetric separators that use only water and centrifugal force to sort loose materials of a certain size proportionally. Due to its poor performance, hydrocyclones are slow to adopt in the process. However, they have the following advantages: they are simple in structure, small in area and less in maintenance, and do not require heavy media and related recycling equipment , Low price and so on. So, if efficient processing equipment is followed, making the hydrocyclone a compelling preselected device. Examples of the use of such equipment are the washing plants at Amherst and Questhronath off, where the cyclone is used to adjust the feedstock (to screen out the bulk of the feed)
