A shredding apparatus for value documents, has two mutually counter-rotatable roller-shaped cutting devices which are disposed opposite each other with reference to a transport path of the value documents to be shredded, in order to cut up the value documents transported along the transport path with the aid of the cutting edges into a multiplicity of value document shreds. A stripper is allocated to each of the cutting devices, which stripper has several stripper elements arranged parallel to each other, which stripper elements engage between the cutting edges of the respective cutting device in order to remove the value document shreds from the cutting edges. The shape of the stripper elements is chosen such that the stripper elements on the front side of the respective cutting device, said front side facing the transport path of the value documents, engage between the cutting edges of the respective cutting device.

A comminuting device for solids-conducting liquids includes a housing with an inlet opening, an outlet opening, and a housing interior extending from the inlet opening to the outlet opening, a first comminuting shaft extending through the housing interior and arranged to rotate about a first comminuting axis. A second comminuting shaft extends through the housing interior and is arranged to rotate about a second comminuting axis. A screening device has a screening wall comprising a plurality of slots arranged in the housing interior adjacent to the first comminuting shaft. A clearing device has a plurality of clearing elements which can be moved relative to the screening wall along a movement path and which extend through the plurality of slots starting from a clearing shaft arranged on one side of the filter wall to at least one portion of the movement path.

The present invention is a Solid-State Stripper Mechanism provides reconciliation and tracking with unique identification tags using a secure and proprietary database, separation, channeling, and collection of data-bearing components from solid-state PCBs, destruction by reducing data-bearing components to 2 mm particle size or smaller rendering the data unusable, use of a screening system to ensure accurate particle size, an internal particle collection system, an air filtration system to preserve air quality where it is located, and collection of solid-state PCBs with unique identification tags after separation of the data-bearing components for secure containment until verification.

The present disclosure is generally related to an apparatus having cutter elements for destroying articles such as paper sheets and a mechanism for separating at least a sheet from a stack in a tray. The separation mechanism can be activated by rotation of the cutter elements. In one embodiment, the separation mechanism is provided in the form of a helical mechanism configured for insertion into the stack and to receive separated sheets from the stack in between its space(s) as it is rotated. The separated sheets can fall via gravity into the shredder mechanism. Optionally, a paper feed mechanism can feed separated paper to the cutter elements. The tray can include an edge to assist in directing separated paper towards the cutter elements. One or more staple picking support mechanisms can also be provided to assist in separating sheets from a stapled set of pages.
