The flow sheet for wet processing typically begins with either a horizontal or inclined primary vibratory screen in either a two or three-deck design. While making the coarse-end separation required, the vibratory screen also provides the introduction point for the addition of water into the process. Water addition begins in the sluicing feedbox and continues with spray bars as the material crosses the screens. The introduction of water in this manner completely hydrates the sand. After exiting the screening process, hydrated sand in slurry form enters a sump and pump arrangement. The pumps used in this process are typically rubber lined due to the abrasive nature of silica sand. The sump and pump arrangement typically provides the slurry to a large-diameter hydrocyclone, the primary function of which is to provide feed material to a hydraulic classifier at an ideal density and in a manner that provides even distribution of the slurry into a stilling feed well.
