Abstract
A device for comminuting media materials that store sensitive information. The device is a rotating mill core with removable flat edged blades, a set of stacked bed knives and a screen. The mill core rotates in close proximity to adjustable bed knives to shear the material being fed before passing through a screen in order to grate the material. The mill core has an angular positioned blade constructed and arranged to shear material with said bed knives. The mill core has a mass and is operated at 1000 rpm. A flywheel is further attached to the mill core in order to conserve rotational energy and improve the efficiency of the device. Vacuum ports facilitate cleanup.
