Abstract
A shaker separates components of a slurry. The shaker has a screen with a pressure differential applied to the screen to remove a portion of a slurry. The pressure differential across the screen can be toggled or pulsed. Generally, various types of separators are used to separate liquids and solids. For example, oil-field drilling operations use separators with screens to remove solids from a slurry. One type of apparatus used to remove solids from drilling mud is commonly referred to in the industry as a “shale shaker.”
