Hard-drive destruction.

The Model 22 HDD Hard Drive Destruction System prevents data theft by shredding used computer hard drives into unreconstructible, irregularly shaped fragments. Made by Security Engineered Machinery of Westboro, Massachusetts, the system can destroy standard drives that measure up to 3 1/2 inches at a rate of 20 per hour. It can also destroy other items, such as hand-held electronic devices, computer backup tapes, and circuit boards. Custom units can destroy other items such as books, bound documents, plastic bottles, and other products. The built-in conveyor automatically adjusts the feeding speed to prevent jamming. Three rotating knives and two stationary bed knives cut the waste until the particles are small enough to pass through a steel sizing screen, selected by the user. The system features safety inter-locks, automatic drive indexing, motor control, and a custom sound enclosure. 417
