Abstract: A cutting assembly includes a core tube. A plurality of blades extends radially outwardly from and is releasably supported by the core tube. The cutting assembly also includes a support member and a sealing member. The support member releasably supports a portion of each of the plurality of blades. The sealing member has a first substantially planar surface cooperating with the support member to secure the portion of each of the plurality of blades intermediate the support member and the first substantially planar surface of the sealing member.

Abstract: The invention relates to a method for rendering waste sorbent material recyclable. The method includes collecting polymer-based sorbent materials containing one or more solvents, treating the waste material in a centrifugal treatment system for removing the solvents from the polymer-based sorbent materials whereby the sorbent materials have a residual solvent content that renders the materials non-hazardous for transportation to a remote recycling site. The treatment system includes a fume collection system and a centrifuge disposed in the fume collection system. The sorbent materials are charged into the centrifuge and the centrifuge is operated for extractive removal of solvents therefrom and collection of the extracted solvents. The sorbent materials are rendered non-hazardous by the centrifugal treatment system enabling the materials to be taken off site for use in making recycled parts.

Abstract: A portable system for recovering oil-based fluids from sorbent articles containing oil-based fluids, the system including a motor vehicle and a self-balancing centrifuge having a housing and a foraminous rotatable basket removably attached to a spindle in the housing, the centrifuge being attached to the vehicle for transport to a remote site, the basket having a solid base having a mass sufficient to provide self-balancing rotation of the basket and the basket being configured for receiving a plurality of the sorbent articles therein, wherein rotation of the centrifuge basket applies sufficient centrifugal force to the sorbent articles to cause removal of oil-based fluids therefrom such that the fluids travel from the basket into an annular area between the basket and the housing and from the housing to a fluid recovery tank and the sorbent articles are essentially fluid free.
