In all hydrocyclones there are two outlets, one for the coarse material, this is the APEX, and the other for the fine material, which is the VORTEX FINDER. The purpose of the Vortex finder is to separate the fine material from the coarse as it spirals around the vortex. The WIDTH of the Vortex finder will determine how far into the coarser ...

For hydrocyclones, the ratio of the amount of a particular particle size recovered from the bottom flow per unit time to the amount in the feed is called the grading efficiency for that particle size. The actual distribution rate of each particle size level in the cyclone bottom flow is shown in Fig. 8. It can be seen from the figure that with ...
