How to Fix Common Issues with Hydrocyclones

This is caused when the hydrocyclone is cutting at the wrong particle size (known as the d50 or p80 cut size of the hydrocyclone), or you want to make a coarser or finer cut. The second step in identifying the problem is to identify if this unwanted performance is constant, or if it is intermittent (meaning the hydrocyclone works properly for a ...

Gypsum Byproduct Processing Solutions

Wet flue-gas desulfurization (FGD) systems generally operate in a pH of 5.0 or above and require feed of reagent to remove sulfur. Limestone slurry is the most commonly used reagent. The quantity of slurry depends mostly on the sulfur levels in the coal. It is common for modern FGD systems to achieve 99 percent removal of SO 2.
