1. A mill system for reducing a size of input material, the mill system comprising:
a stationary housing that defines a cavity with a circumferential perimeter, the housing having:
an outer wall having an inner surface; and
an interior layer that extends over the inner surface of the outer wall about the circumferential perimeter of the cavity, wherein the interior layer comprises a flexible mat, a plurality of tiles, and a plurality of strike plates;
wherein the plurality of tiles are secured to and extend from the flexible mat, wherein the plurality of tiles are composed of ceramic material, wherein the plurality of tiles have top surfaces that are spaced from the flexible mat and are positioned relative to each other via a plurality of first bevels, and wherein the plurality of first bevels define tapered structures that taper away from the flexible mat and interface to one another with no gaps between the plurality of tiles in a direction extending about the circumferential perimeter of the cavity when the interior layer extends over inner surface of the outer wall; and
wherein the plurality of strike plates are composed of the ceramic material and are secured to and extend from the flexible mat, wherein each strike plate of the plurality of strike plates extends from the flexible mat between a pair of tiles beyond the top surfaces of the pair of tiles, and wherein each strike plate has second bevels that define a tapered structure that tapers away from the flexible mat and interface to the pair of tiles with no gaps between the strike plate and the pair of tiles in the direction extending about the circumferential perimeter of the cavity when the interior layer extends over inner surface of the outer wall;
wherein the plurality of tiles, and the plurality of strike plates are positioned on the flexible mat in a repeated pattern;
a base configured to support the housing thereon and configured to rest on a ground surface;
a rotor having one or more rotor blades;
a drive shaft secured to the rotor; a motor secured to the drive shaft and configured to rotate the rotor;
a feed input chute configured to intake the input material; a feed portal configured to connect the feed input chute and the cavity; and
a product exit portal configured to allow the input material to exit therefrom;
wherein the one or more rotor blades are configured to move the input material against the plurality of strike plates and the plurality of tiles when the rotor is rotated.
