Cone strainers, or witches hat strainers,  are generally a temporary devise inserted within a fluid production line to provide filtration and protection for the pumps, valves, meters, and other mechanical components that could be otherwise impacted by the pass-through of particulate matter within the processing system. Exactly like it sounds, a conical strainer is shaped like a cone. The cone strainers are typically constructed of wire mesh of varying materials and apertures, based on the facility’s processing needs.
