The present invention discloses an automatic paper feeding method for a paper shredder and a paper shredder, including a step of disposing paper, a step of pressing paper, a step of automatically feeding paper continuously, and a step of shredding paper. The paper sheets to be shredded entering the automatic paper feeding channel are superimposed partially; the paper disposing mechanism and the automatic paper feeding channel of the paper shredder are located at two sides of the paper rolling device respectively; the paper rolling device is located at least at the position above the lower end portion of the paper disposing area/paper sheets to be shredded. In the present invention, the paper sheets to be shredded conveyed to the automatic paper feeding channel are superimposed partially; during shredding, the shredding cutter shreds a plurality of paper sheets to be shredded at a time, with a higher feed speed and an increased shred speed. Besides, the automatic feed speed can be adjusted. The present invention has an intelligent paper feeding function, which effectively prevents the overload during the automatic paper feeding and the automatic shredding.

A bone grinder is provided herein. The bone grinder may have a grinding chamber, an intermediate zone, and a primary cutting element and a secondary cutting element. The intermediate zone may have a first wall and a second wall within the grinding chamber, and the intermediate zone may separate the primary cutting element from the secondary cutting element. The first wall and the second wall may slope inward such that a distance between the first wall and the second wall generally decreases from the primary cutting element to the secondary cutting element. The primary cutting element and the secondary cutting element may be positioned within the grinding chamber to sequentially perform primary cutting operations and secondary cutting operations on a bone. A drive mechanism may operatively engage the primary cutting element and the secondary cutting element.

A distributor device for solids-laden fluids comprises a distributor housing having a housing underside and a housing topside opposite the housing underside which define an interior space that is subdivided into a fluid space into which the inlet port opens and a ventilation space separate therefrom into which the ventilation port opens. A plurality of outlet ports, an inlet port in the distributor housing, a ventilation port disposed in the housing topside of the distributor housing, and a distributor unit are also included. The disributor unit is movable relative the distributor housing and disposed inside the distributor housing, and connects each of the outlet ports in fluid communication with the fluid space and with the ventilation space in alternating succession. Relative movement of the distributor unit connects an outlet port of the plurality of outlet ports alternately with the fluid space and the ventilation space.

A smoking accessory assembly facilitates storing and transporting accessories for grinding smoking matter and rolling the smoking matter for smoking. The assembly includes a housing having a plurality of compartments. A grinder has a plurality of grinder teeth and a peripheral wall enclosing the grinder teeth. A plurality of cap teeth is coupled to and extends from a top cap. The grinder is insertable into the top cap for grinding plant matter. A funnel tapers away to a tube section extending from a base of the funnel. Openings extend through the grinder for passing ground plant matter through the funnel and into the tube section. The tube section is open for passing the ground plant matter into a rolling paper wrapped around the tube section.

The present invention involves a system and method for grinding herbs, tobacco, marijuana and the like. The herb grinder system herein includes interchangeable and replaceable lower grinder plates that are secured in place with threading, bayonet mounts or the like. The upper and lower grinding plates are provided with blades having a modified diamond shape which provides extremely sharp leading edges regardless of which direction the grip assembly of the grinder housing is rotated. The lower plates are also provided with variations in the size, shape and arrangement of hole sizes through which the ground material is allowed to pass through. This construction provides the user with the ability to control his/her grind size mixture, which may be consistent sized grinds or a mixture of different sized grinds.
