CHAPTER 2. LITERATURE REVIEW

In tackling this problem it is important to first define what exactly is the maximum spigot capacity, and establish what determines it. Jull (1972), and Mular and Jull (1978) suggested that the spigot capacity of a hydrocyclone was reached at the onset of rope discharge at the underflow.

The Sizing & Selection of Hydrocyclones

HYDROCYCLONES By Richard A. Arterburn For many years, hydrocyclones, commonly referred to as cyclones, have been extensively utilized in the classification of particles in comminution circuits.

With a Hydrocyclone, this is accomplished by adjusting the spigot size. Too small of a spigot will cause roping in the Hydrocyclone and decrease separation efficiency, while too large a spigot will increase the bypass. For these reasons, Hydrocyclones work best when the throughput or tph is consistent.

Unlike hydrocyclones open to air, water was used to seal the vortex finder and the spigot so that air could not enter. The experiment result showed that there was no air core in the water-sealed hydrocyclone, and the separation performance of the water-sealed hydrocyclone was better than that of ordinary hydrocyclones. Swain et al. [17] used the

Hydrocyclones | McLanahan

The air core is formed at the spigot/apex as air is drawn in to the Hydrocyclone. The vortex finder provides a pathway for the air to exit the body of the Hydrocyclone. As the air flows through the vortex finder, the fluids and finer fractions are dragged along to perform the classification of materials.
