ABSTRACT:
No-oil high-security shredders, other no-oil shredders, and other no-oil machinery are provided. By using zero-clearance and a sacrificial material, the need to oil shredder machinery has been eliminated. A single no-oil destruction machine advantageously may receive (with minimal operator intervention) a mixed input load, such as a mixture of a combination of paper (including paper that is folded, ripped, stapled, or otherwise irregular), CDs, DVDs, polyester, plastic cards, SMART cards, wood, Verichips, flash drives, biometric chips, and/or other generally-planar materials.
