Improved free-swinging hammermill hammer configurations are disclosed and described for comminution of materials such as grain and refuse. The hammer configurations of the present disclosure are adaptable to most hammer mill or grinders having free-swinging systems. The configurations as disclosed and claimed are non-forged and incorporate a saddle or hammer mouth. The merging of a hammer and saddle improves strength to reduce or maintain the weight of the hammer while increasing the amount of force delivered to the material to be comminuted. The improved configurations incorporate comminution edges having increased hardness for longer operational run times. The improved configurations improve installing, removing, and cleaning hammer components within the hammermill. The improved configurations may incorporate hammermill rod hole of varying shapes and sizes and saddles of varying shapes and sizes or the use of non-planar hammer bodies that have a recessed or protruding surface.

A multistage hammer mill (10) has a plurality of milling stages arranged concentrically about each other. The plurality of milling stages arranged so that substantially all material in a first inner most of the milling stages passes through all subsequent adjacent milling stages. The milling stages include a first milling stage and a second milling stage. A central feed opening (12) enables material flow into a primary impact zone (14) of the first milling stage. The first milling stage has an impact mechanism (16) and a first screen arrangement (20a). The impact mechanism (16) rotates about a rotation axis (18). The first screen arrangement (20a) is disposed circumferentially about and radially spaced from the impact mechanism (16) and is provided with a plurality of apertures (22) through which impacted material of a first size range can pass. The second milling stage has a second arrangement (20b) disposed circumferentially about and radially spaced from the first screen arrangement (20a) and a circular array of impact elements (50a) disposed between the first screen arrangement (20a) and the second screen arrangement (20b).

A quick blade repair and replacement enabled apparatus integrating medical waste shredding and sterilization is a dismountable integrally assembled vertical structure. Three chambers, including a loading and stirring, a shredding and a sterilization and discharging chamber are connected into a whole. Two repair gates are respectively on the left and right sides of the shredding chamber, they are designed as a whole together with the rotary blade shaft, when repair and replace the blades, only the repair gates need to be dismounted, and the replacement process can be finished outside the shredding chamber. The stationary blades are pressed on the inner wall of the shredding chamber by using binder plate, and bolts for securing the binder plate are screwed from outside.

Apparatus to reduce size of a light, dry, fibrous material, particularly straw, with a material supply area (1), an impeller (2) and a material release area (5) for the size reduced material as well as a ring element (4), which is arranged with a distance to the impeller (2), wherein least one size reduction tool (6) is provided at the impeller (2) and/or at the ring element (4), that is provided angular shaped, particularly L-shaped, or having the shape of a polygonal, particularly ashlar-formed, hollow profile or solid profile. Splitting particularly hard, closed fibrous structures such as nodes of straw can thereby be enabled to a major portion without excessive shortening of the straw.

An assembly for reducing the size of suspended solids in a pump intake including a rotatable element and a screen configured to locate in a position between a pump and the rotatable element.

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.

A rotary mill for grinding recycled glass materials into particles has a housing defining an impact chamber with a rotor in the chamber at the bottom of an inclined guide wall underneath the feed opening. The rotor has a plurality of axially extending, angularly spaced massive impact hammers so that the impact hammers impact and deflect the solid materials onto a plurality of shatter bars located at the peripheral wall. Each of the impact hammers has a leading blade element of a hardened steel which has a front face inclined relative to a bottom portion of the guide surface so that an outer edge of the front face is angularly advanced relative to an inner edge thereof.
