An apparatus and method for processing a crop residue, which includes but is not limited to, destroying weed seeds present in the crop residue. The apparatus (10) comprises an elongate housing (12) having an inlet (20) for receiving crop residue N and an outlet (22) for discharging the crop residue. The apparatus (10) also has one or more rotors (24), (26) located in the elongate housing (12). Each rotor (24), (26) comprises a plurality of radially extending impact members (28a), (28b), (28c), (28d), (28e), (28f) which rotate with the one or more rotors (24), (26) and impact against the crop residue, so that lighter material of the crop residue is subjected to less impacts and denser material of the crop residue is subjected to relatively more impacts.

A pick system includes a holder and a pick assembly. The holder includes a first end, a second end, and a bore extending between the first end and the second end and defining a longitudinal axis. The surface of the bore may be tapered so that the diameter of the bore proximate the first end is greater than the diameter of the bore proximate the second end. The pick assembly includes a shaft. The shaft is received within the bore of the holder along the longitudinal axis, and the shaft may be tapered to mate with the bore.

A rotary collider air mill apparatus that uses accelerated air moving at high velocities as the primary reduction medium is described. The apparatus produces turbulent air currents and shear waves within a polygonal housing whereby solid particles introduced into the housing repeatedly collide with each other and are fractured into smaller particles. An exemplary rotary collider air mill apparatus may include a polygonal housing having a front plate and a back plate and 5 or more side plates, a drive shaft passing through the central portion of the polygonal housing, a sprocket mounted on the drive shaft and having arms extending radially from a central hub, and 3 or more blade sections attached to the arms. The rotary collider air mill apparatus is scalable upward or downward in sizes ranging between 12 inches and 144 inches in diameter with the housing and internal mechanisms sized proportional to one another.

A mill includes a housing with a first end portion, a second end portion, and a lateral area disposed therebetween. The housing includes a raw material inlet, an air inlet, a recirculated material inlet, and a material outlet. An impeller is supported by the housing and includes a shaft disposed along the longitudinal axis of the housing, with a plurality of curved blades. A method for milling includes receiving a material of a first size range, introducing the material to an apparatus via a first inlet and introducing air into the apparatus via a second inlet. The method also includes agitating the material via an impeller, where the agitation reduces at least some of the material to a second size range by the time the material reaches an outlet of the apparatus. The processed material is delivered to subsequent processing operations.

Filter material, mainly in form of industrial remnants from the production of the filter fillings, is processed without the intake of the heat in such a way that it is cut in the disintegrator (4) at the presence of the air, where the material is during retention time repeatedly led to the contact with the rotating blades and bunches emerge in the disintegrator (4) through aeration. The flat carrier (3) is thus at least partially disintegrated to the original fibers (1); the released fibers (1) intertwine into bunches and the active carbon (2) is released from the original bond with the flat carrier (3). The swirl (vortex) created inside the disintegrator (4) carries the dust particles of the active carbon (2) and they adhere to the surface of the fibers (1). Part of the released active carbon (2) is—after the separation—carried away from the emergin bunches, which in the lower part of the disintegrator (4) run through the sieve out of the disintegrator (4). The resulting product is advantageously applicable as heat and noise isolation in all fields of technology, for example construction. The separated active carbon (2) in form of granules is also a resulting product of processing.

A multifunctional extruding-shearing machine and an application of the machine is disclosed. The main technical feature of the machine is that the outer surface of the wear-resistant component made of hard alloy on the rotor pin and stator pin is covered with 4-12 step teeth, and the surface of the step teeth of the stator pin faces the inside and the surface of the step teeth of the stator pin faces outside when the equipment is assembled, and the rotor pin wear-resistant member tip faces the stator pin wear-resistant member tip. The above structural features ensure that the rotor pin and the stator pin can clamp the material particles and exert extrusion shear force on them to force them to be crushed.
