1. A modular industrial reducing machine, comprising:
a hopper designed to guide material into a reducing compartment;
a base frame removably coupled to the hopper and including a first and a second sidewall and first and second axial endwall, wherein the first and second sidewalls and the first and second axial endwalls form an enclosure;
a drive assembly coupled to the first and second axial endwalls and a rotational shaft with a plurality of cutters; and
a removable cutting tray releasably coupled to the first and second axial endwalls and located within the enclosure, the removable cutting tray including a plurality of non-rotating anvils designed to interact with the plurality of cutters during reducing operation to reduce material in the reducing compartment, and a plurality of reinforcement ribs on exterior walls of the cutting tray, wherein the exterior walls of the cutting tray are parallel to the first and second sidewalls of the base frame, and wherein at least one of the first and second axial endwalls includes at least one axially aligned boss mated with a slot in a removable cutting tray;
where the first and second axial endwalls are removably coupled to the removable cutting tray via a plurality of axially aligned attachment apparatuses laterally extending through openings in at least one of the first and second axial endwalls and the first and second sidewalls.
 
8. A method for disassembling a modular industrial reducing machine, comprising:
decoupling an attachment apparatus connecting a removable cutting tray and a base frame;
decoupling a first slot and a second slot on opposing exterior sides of the removable cutting tray from a first axially aligned boss on an interior side of the base frame and facing the removable cutting tray of a first axial endwall and a second axially aligned boss on an interior side of the base frame and facing the removable cutting tray of a second axial endwall in the base frame; and
removing the removable cutting tray from within the base frame formed by the first and second axial endwalls and a first and a second sidewall;
where during removal of the removable cutting tray from within the base frame, a plurality of bearings, a hydraulic motor, and/or a hydraulic conduit in a drive assembly remain in a substantially fixed position with regard to the base frame.
 
11. A modular industrial reducing machine, comprising:
a hopper designed to guide material into a reducing compartment;
a base frame removably coupled to the hopper and including a first and second sidewall and first and second axial endwalls forming an enclosure;
a drive assembly coupled to the first and second axial endwalls and a rotational shaft with a plurality of cutters; and
a removable cutting tray releasably coupled to the first and second axial endwalls and including a plurality of non-rotating anvils, wherein each anvil has an opening in a respective side wall, wherein the removable cutting tray is located within the enclosure, at least one of the first and second axial endwalls including at least one axially aligned boss mated with a slot in the removable cutting tray, the first and second axial endwalls configured to be removably coupled to the removable cutting tray via a plurality of axially aligned attachment apparatuses laterally extending through openings in at least one of the first and second axial endwalls and the first and second sidewalls; and
where the plurality of non-rotating anvils are welded to cross-members laterally extending across and non-removably coupled to a tray housing.
