The Sizing & Selection of Hydrocyclones
The size of this orifice is determined by the application involved and must be large enough to permit the solids that have been classified to underflow to exit the cyclone without plugging. The normal minimum orifice size would be 10% of the cyclone diameter and can be as large as 35%. Below the apex is normally a splash skirt to

Our Cavex® Hydrocyclone Range Weir
A hydrocyclone, or "cyclone", is a piece of equipment that uses centrifugal force to classify and separate solid particles from a liquid or mixed medium based on size, shape and specific gravity. It has a simple structure with one inlet on the tangent direction and two discharge openings along the axis direction.
