A process for fibrillating a fibrous pulp, and products made using the same. The process comprises providing a fibrous pulp of liquid and staple fibers having a first liquid to fibers ratio of less than or equal to 6:1, applying stress to the pulp to fibrillate the staple fibers; and, during said applying stress, drying the pulp to a second liquid to staple fibers ratio of less than or equal to 0.43:1.

A rotary crushing apparatus includes a container (including a stationary drum, a rotating drum, and a top plate) into which a processing object containing raw material soil is fed. A rotating shaft extends in the vertical direction, and an impact member rotates in the rotating drum by the rotation of the rotating shaft to crush the processing object. Then, the rotating shaft is provided in such a way as to penetrate the top plate 10a, and the rotating shaft is rotatably held via ball bearings provided in the vicinity of the top plate. In addition, the lower end of the rotating shaft is a free end.

A modular system for performing a plurality of crushing and grinding processes, including: a plurality of interchangeable milling heads, each interchangeable milling head having a milling mechanism configured to perform one of the plurality of crushing and grinding processes when driven; a driving unit including a driving motor having a range of motor characteristics; and a connecting unit configured to functionally connect one of the interchangeable milling heads to the driving motor such that, when connected, the one of the plurality of interchangeable milling heads can perform the one of the plurality of crushing and grinding processes. Each of the plurality of interchangeable milling heads further includes an adaptor unit configured to connect the milling head to the connecting unit and for converting the range of motor characteristics of the driving motor into the milling driving characteristics of the connected interchangeable milling heads.

An impact crusher is provided which comprises a frame defining a crushing chamber, a rotor provided with at least one hammer, at least one impact apron plate, and a rotor positioning device configured to adjust a rotational position of the rotor. The rotor positioning device comprises a piston motor coupled to the rotor and having a cylinder block comprising a plurality of cylinders; a plurality of pistons, a respective piston being slidably mounted in a respective cylinder; and a surface against which the pistons are configured to exert a force. The cylinder block and the surface are arranged for relative rotation, and the cylinder block or the surface is operatively coupled to the rotor, such that relative rotation of the cylinder block and the surface causes rotation of the rotor. The rotor positioning device is operable in first and second modes.

An abrasion wear resistant plate mountable to a rotor of a vertical shaft impact crusher includes a metallic main body, and at least four non-metallic tiles arranged on an upper surface of the main body to form a portion of a contact face facing an internal space of the rotor. Each of the tiles have an abrasion wear resistance greater than that of the main body, each one of the tiles having at least three edges each matching with and positioned against an edge of a neighboring tile.

A pulverizer for reducing a size of input material particles having a housing, a rotatable shaft with rotor arms and at least one airflow deflector cooperating with the rotor arms to deflect airflow within the pulverizer so as to form at least two overlapping vortices within the interior chamber such that input material particles in suspension in both overlapping vortices collide with each other to be thereby pulverized. The pulverizer also having a housing liner including a plurality of housing liner portions attached to and extending along a outer structural wall of the housing. The pulverizer also having a housing sidewall having an outer structural wall with a plurality of wall sections. The pulverizer also having canted rotor arms and rotor arms with removable wear pads. An anti-caking device for a vessel such as a pulverizer is also provided.

An impact crusher for grinding and separating solid material has a base, a rotor on the base having an upright shaft defining an upright rotor axis about which the rotor is rotatable, and a drum fixed on the base, spacedly surrounding the rotor, and formed by a pair of generally semicylindrical drum shells fitted together at a plane including the rotor axis. An array of axially extending and angularly substantially equispaced replaceable ribs is provided on an inner surface of the drum. A plurality of impact hammers are angularly substantially equispaced around the rotor and orbitable past the ribs on rotation of the rotor.

Embodiments relate to one or more techniques that may be employed alone or in combination, in the refurbishment or recycling of used solar modules. In certain approaches, a (heated) wire may be used to cut through one or more layers (e.g., front encapsulant, back encapsulant, both front and back encapsulant, backsheet) of a solar module that is being recycled or refurbished. Some approaches may employ testing of a used solar module, alone or in combination with information (e.g., as part of a received package) regarding parameters of a used solar module such as panel size, width, length, height, thickness of glass, or others. According to specific embodiments, used solar modules may be subjected to various cleaning processes at one or more points during refurbishment/recycling.
