Contribution to the understanding of the three product
The three product cyclone is a modification of the conventional hydrocyclone with an additional vortex finder termed the inner vortex finder inserted concentric to the existing one, termed the outer vortex finder, resulting in three products from the same hydrocyclone. The three product cyclone produces a finer overflow stream, an intermediate overflowprising fine high density

Circulating Load Calculation Formula
Here is a formula that allows you to calculate the circulating load ratio around a ball mill and hydrocylone as part of a grinding circuit. For example your ball mill is in closed circuit with a set of cyclones. The grinding mill receives crushed ore feed. The pulp densities around your cyclone are sampled and known over an 8 hour shift, allowing to calculate corresponding to circulating load

Hydrocyclones McLanahan
Hydrocyclones and Separators are selected based on several parameters, including volume of flow, tons per hour of recoverable material and cut point required. Larger units process higher volumes however, the larger the Hydrocyclone, the coarser the cut. Therefore, processing a larger volume of slurry with the need to recover finer fractions would lead to the selection of several smaller units.

CHAPTER 3 SLUDGE THICKENING Marmara Üniversitesi
CHAPTER 3 SLUDGE THICKENING Thickening is a procedure used to increase the solids content of sludge by removing a portion of the liquid fraction. To illustrate, if waste activated sludge, which is typically pumped from secondary tanks with a content of 0.8 solids, can be thickened to a content of 4 solids, then a fivefold decrease in sludge volume is achieved . Thickening is generally
