A quick blade repair and replacement enabled apparatus integrating medical waste shredding and sterilization is a dismountable integrally assembled vertical structure. Three chambers, including a loading and stirring, a shredding and a sterilization and discharging chamber are connected into a whole. Two repair gates are respectively on the left and right sides of the shredding chamber, they are designed as a whole together with the rotary blade shaft, when repair and replace the blades, only the repair gates need to be dismounted, and the replacement process can be finished outside the shredding chamber. The stationary blades are pressed on the inner wall of the shredding chamber by using binder plate, and bolts for securing the binder plate are screwed from outside.

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.

A cutter holder has two limbs extending at an angle to each other. A cutter is mounted on one side of the cutter holder. An opposite side of the cutter holder has a prism-shaped cavity defined thereon. The cavity has a V-shape cross-section having a recessed groove at a base of the V-shape. A center line of the recessed groove is laterally offset from a center line of the cutter holder.
