Definition and Conceptual Framework
The blind hole rate of filter screens refers to the proportion of total surface area occupied by blind holes relative to the entire surface area of the screen. Blind holes are cavities intentionally created in filter screens to enhance filtration capabilities by increasing the available surface area for capturing particles or facilitating fluid flow dynamics. This parameter is crucial in determining the specific filtration properties of a screen, including porosity, pressure drop, and particle retention efficiency.
