The portable electronic grinder system provides a pocket-sized electronic herb grinding device for grinding at least one item.

The present disclosure relates to a material reducing apparatus adapted to be coupled to a vehicle by a pivot arm or other structure. The material reducing apparatus includes a reducing head with rotary reducing component. The reducing head can be titled about a tilt axis relative to the vehicle and can be raised and lowered relative to a vehicle. The reducing head has a thrown object deflector that automatically moves relative to the rotary reducing component when the reducing head is tilted relative to the vehicle.

An apparatus for producing spherical metallic powders through continuous ball milling. The apparatus includes a comminution component. The comminution component includes an inlet to receive a metallic material at a first region within the comminution component and an outlet to dispense the metallic powder from a second region within the comminution component. The apparatus includes a plurality of grinding components to grind the metallic material, the plurality of grinding components being arranged within the comminution component. The apparatus includes a drive component, connected with the comminution component, to induce movement of the metallic material and the plurality of grinding components within the comminution component such that the metallic material is fragmented through contact with the plurality of grinding components at the first region and an external surface of the fragmented metallic material is altered at the second region to produce the metallic powder.

A paper shredder, comprising a housing provided with a paper inlet, a motor arranged in the housing, a control circuit module for controlling the motor to operate, at least one inductive electric conductor and a human inductive signal processing output module, wherein the inductive electric conductor is arranged at the inner wall of the housing near the paper inlet; the inductive electric conductor and the inner wall of the housing are in isolating contact or have a gap; the inductive electric conductor is electrically connected with the human inductive signal processing output module; and the human inductive signal processing output module is electrically connected with the control circuit module. The paper shredder has the advantages of simple structure, low cost, high safety and reliability, etc.

A paper shredder bin-full sensor with a push bar, a conductive element coupled to the push bar, a sensing contact assembly normally set apart from the conductive element, and a signaling contact coupled to the sensing contact assembly. Sensor includes a push bar sweeper between the conductive element and the push bar, and a biasing element coupled to the push bar sweeper, the biasing element elastically resists the shredded material force. A predetermined shredded material force presses the push bar, causing the conductive element to couple to the sensing contact assembly, in turn causing a waste bin-full signal to emanate. Push bar can be articulated and non-articulated. Articulated push bars include upper and lower push bars, and respective tensioning element connecting the respective upper and lower push bars. Lower push bar is extended from upper push bar. Paper shredder can have articulated or non-articulated push bars.

A waste processing system includes a cutting system and a feed system, wherein the improvement relates to a safety and control system which comprises a side mount actuator having at least two operable positions, wherein the actuator is in communication with the waste processing system and is adapted to selectively control the operation thereof.

A shredding module of a shredding apparatus is disclosed. The shredding module includes a shredder cassette receiver and a shredder cassette received within the shredder cassette receiver. The shredding cassette includes two shredding shafts arranged in parallel and rotatable about respective rotation axes, and two sets of fingers that cooperate with the two shredding shafts to shred material. The shredder cassette is slidably movable in an axial direction of the respective rotation axes into and out of the shredder cassette receiver.

A material processing device has a rotor coupled to a rotatable shaft, and a rotor control system. The rotor control system comprises a rotor control mechanism with a first engagement member that is engagable with a second engagement member coupled to the shaft. The rotor control mechanism is operable into and out of an engaged state in which the first and second engagement members are engaged with one another. In the engaged state, the rotor control mechanism is operable in a locking mode in which the first engagement member is fixed in position to prevent rotation of the shaft, or in a rotation mode in which the first engagement member is movable to rotate the shaft. The material processing device may be a crusher, a shredder or a milling machine.

A shredder has cutter elements for destroying articles (paper) and a feed mechanism for advancing paper from a stack in a tray into cutters for shredding. The feed mechanism has a feed member provided adjacent to the tray with an elastic arm for engaging and disengaging the stack. The feed member rotates in a feeding direction about an axle, with the elastic arm elastically deforming to apply pressure to feed paper atop the stack to the cutters. The elastic arm can include a protruding tip that is inserted into the stack. The tray includes a curved feed bed to assist in feeding paper into the cutters and deforming the elastic arm. A pivot arm can also move the feed member relative to the tray (e.g., vertically). A disengagement mechanism can hold the feed mechanism in an inoperable feeding position when a drawer or tray is moved into an open position.

A novel safe paper feed opening structure of a paper shredder, having a shredder upper cover and a paper shredder plate. The shredder upper cover has an opening, and the paper shredder plate is at the opening. The opening communicates with a moveable feed throat. The paper shredder plate can be configured in one of four positions. The moveable feed throat has a normal opening and a wide opening. The feed throat can be moved to the wide opening when the shredder plate is in a JAM CLEAR/OFF position. The CLOSED/OFF, NORMAL/ON, and SHRED-SAFE/OFF positions use a normal feed throat. A method for operating a paper shredder includes providing a shredder upper cover; providing the shredder upper cover with an opening; disposing a paper shredder plate at the opening; disposing the opening in communication with a moveable feed throat; and moving the feed throat responsive to a paper shredder condition.
