Adaptive architecture solids diverter and comminutor

A system for comminuting solid waste material comprising:

• a casing defining a comminution chamber having two side walls and being open on opposite sides thereof for permitting the flow of liquid therethrough bearing solid waste material and being adapted for connection in a solid waste disposal line;
• a shredding device disposed within the casing and comprising parallel first and second shredding stacks that include first and second parallel shafts rotabably mounted between an upper shredding device housing and a lower shredding device housing, each of the first and second parallel shafts including a plurality of cutting elements mounted such that a plurality of first cutting elements on said first shaft are in an interspaced relationship with a plurality of second cutting elements mounted on said second shaft, each of said cutting elements having at least one cutting tooth thereon, said cutting elements being positioned between and separated in an axial direction by spacers which are coplanar with the cutting elements of an adjacent stack such that a cutting element from one stack and a spacer from an other stack form a pair of interactive shredding members;
• a rotating screening drum disposed within the casing and mounted between an upper screening drum housing and a lower screening drum housing, the rotating screening drum configured to permit fluid to pass therethrough while capturing solids on an outer surface for delivery to shredding device, an upstream portion of the rotating screening drum disposed upstream of an upstream portion of the shredding device,
• wherein the upper shredding device housing and the lower shredding device housing are separate members from the upper screening drum housing and the lower screening drum housing;
• an interconnecting frame that connects the shredding device and the rotating screening drum to at least one wall of the two side walls, the interconnecting frame including a surface extending a vertical length of the rotating screening drum and the shredding device and configured to form a seal with a front face of the shredding device to prevent the flow of liquid from passing between the at least one wall of the two side walls and the shredding device.

• and
• an interconnecting frame that connects the shredding device and the rotating screening drum to at least one wall of the two side walls, wherein the interconnecting frame includes an adjusting mechanism to adjust the position of the shredding device toward or away from the rotating screening drum,
• wherein the upper shredding device housing and the lower shredding device housing are separate members from the upper screening drum housing and the lower screening drum housing.

• wherein the rotating screening drum is formed using perforations to permit fluid to flow therethrough, and the size of the perforations vary along the surface of the rotating screening drum along a vertical direction,
• wherein the perforations are smaller at a bottom of the rotating screening drum than at a top of the rotating screening drum.
