Abstract
A centrifuge screen clamp comprises a body and a screen retaining portion connected to the body. The screen retaining portion comprises a pressure fitting surface and a clamp interface member engaging surface. In one embodiment, the pressure fitting surface is a substantially planar surface disposable on a screen portion of a centrifuge screen and the clamp interface member engaging surface is disposable on a clamp interface member disposed on the screen. The clamp interface member engaging surface operates to apply a counteractive force against the clamp interface member, which counteractive force is substantially coplanar with an inertial sliding tendency direction of the screen during rotation.
