Abstract

A method for combining three different means of constructing the concentric layers of the outer collecting wall for industrial size centrifuges, whereby treating the inward-facing elements of easily cast or stamped materials using processes such as Physical Vapor Deposition, Chemical Vapor Deposition or metal plating, transforms them into an innermost member with superior hardness and durability, and whereby said wear surface member or deposited layer is physically supported by a middle composite layer made up of one or more investment castings designed to optimally transfer centrifugally-induced compression loads from the innermost wear surface toward the outer surface of the composite wall, such castings being of ceramic, metals or other materials, and whereby the outer surface of said composite wall is comprised of a filament-wound hoop strength reinforcement layer, using aramid, graphic, carbon or such fibers mixed and embedded in resin, such that all highly desirable characteristics for a centrifuge outer, heavies-collecting wall are provided, including interior hardness and wear abrasion, incompressibility and intrinsic dynamic balance, and substantially higher hoop or bursting strength, than can be attained through any metal-crafted centrifuge outer wall, and, model for model, for substantially lower design and fabrication costs.
