A method and apparatus for applying a wear coating to the back side of a wear part.

Caden edge welding process

A face plate is provided for releasable attachment between a hammer and a hammer tip of a size reducing machine. The face plate provides a buffer between the hammer and the hammer tip. The hammer has a body with a forward facing hammer face that aligns with the back of the face plate. The front of the face plate aligns with the back of the hammer tip. The hammer, hammer tip, and face plate contain aligned bolt holes for receipt of a securement bolt that releasably secures the hammer, face plate, and hammer tip. The face plate includes a center section raised above opposing ledges designed for mated alignment with a recessed center section of the back of the hammer tip.

Intermediary face plate for saddle-back hammer tip

A mated hammer and hammer tip combination for releasable engagement are provided. The hammer includes a lower body portion for engagement with a rotor of a size reducing machine, and an upper body portion. The upper body portion of the hammer includes at least one bolt hole and a front face having a raised center section. The hammer also includes an upper and lower ledge, and recessed side grooves. The hammer tip includes a front face with a distally located working edge for debris impact, at least one bolt hole for receipt of a bolt to releasably engage the hammer and hammer tip, and a back having a plurality of protruding opposable members, comprised of opposable shoulders or feet that define a recessed section therebetween forming a saddle-back. The saddle-back in the back of the hammer tip releasable engages with the raised center section of the hammer. The hammer tip and hammer are precision milled to ensure that the fit between the saddle-back of the hammer tip and the raised center section of the hammer is of a tolerance that is less than the tolerance between the bolts and bolt holes.

Saddle-back hammer and hammer tip

The invention comprises a rotor and hammer assembly comprising a drive shaft allowing for rotating the rotor and hammer assembly. End plates are secured to the drive shaft, and a rotor casing is secured to the end plates. The rotor casing has an outside surface, to which a hammer is removably secured. The outer surface of the rotor casing includes slots, having a first and second slot section with a raised center portion therebetween. The hammer has a substantially flat base with a centrally located notch, such that the hammer base and the slot matingly align. The hammer is further secured to the outer surface of the rotor casing with threaded bolts. The hammer includes a front face with a raised center section and recessed comers that matingly align with the hammer tip, and is further secured with threaded bolt and nut.

Removable hammers for use with a rotor and hammer assembly

A hammer comprising a hammer body. The hammer body comprises a rotor forming portion with a trailing and a leading edge and is capable of securement to a rotor, a tip support section capable of extending into a debris path, and a production pocket extending from the leading edge of the rotor portion also capable of extending into the debris path. The hammer also comprises a hammer tip secured to the tip section of the hammer body and at least partially shielded from the debris path by the production pocket of the hammer body.

Production plus hammer with protective pocket

The present invention embodies an insert for attachment to a hammer of a size reducing machine for use in size reducing waste material, comprising a body with a centrally located mounting hole to allow for attachment of the insert to the hammer. The body also includes a bullet shaped tip distally located in relation to the body, wherein the tip can size reduce waste material on impact.

Rotatable hammer insert with bullet tip

A hammer and rotor assembly for a size reducing machine. The rotor of the assembly comprises a drive shaft for rotating the assembly. The drive shaft includes a drive end and an outboard end, wherein the drive end secures to the drive motor of the size reducing machine. End plates secure the drive end and outboard ends of the drive shaft, and a center support also secures to the drive shaft. A rotor casing is secured to the end plates and the center support. The assembly includes a plurality of hammers having a hammer body with a rotor forming portion capable of securement to the rotor casing, a tip support portion extending into the debris path from the rotor forming portion of the hammer body. The hammer body also includes a production pocket. A rotatable hammer tip with a working edge and a protected edge is secured to the tip support section of the hammer body such that the hammer tip is at least partially shielded from the debris path by the production pocket.

Production plus hammer with protective pocket and rotor assembly

The present invention comprises a size reducing machine with a rotor having a plurality of hammers arranged to size reduce waste material upon impact. The rotor is contained with a tub that includes a tub floor for feeding the waste material toward the rotor. Located proximate to the tub floor is a gator plate with a serrated edge for initial material for sizing of the waste material.

Size reducing machine with serrated top wear plate

A rotor assembly for use with size reducing machines having a drive motor comprising a central shaft with a drive end for securement to the drive motor and an opposing outboard end. The rotor assembly also comprises a webbing engaged with the central shaft for supporting the rotor assembly, a rotor casing substantially seals the webbing, and a plurality of sockets secure to a plurality of casing throughbores. The webbing comprises a drive end plate secured to the central shaft with a bushing, an outboard end plate secured to the central shaft with a bushing, and a plurality of web support sockets aligned in two transversely aligned rows. The web socket plates each comprise two socket receiver channels for alignment with the sockets. Finally, a plurality of hammers releasably secure to the plurality of sockets.

Millennium rotor assembly

A hammer tip is provided with a centrally located bolt hole for receipt of at least one bolt for releasable securement to a hammer. The hammer tip includes a front face having a working edge, and a back with two opposing shoulder sections with a recessed section therebetween. The hammer includes a support shoulder for receipt of the bottom of the hammer tip. Together, the shoulder sections, the recess formed between, and the support shoulder create a saddle-back for releasable integration with the hammer.

Saddle-back hammer tip

A rotor assembly for use with size reducing machines having a drive motor comprising a central shaft with a drive end for securement to the drive motor and an opposing outboard end. The rotor assembly also comprises a webbing engaged with the central shaft for supporting the rotor assembly, a rotor casing substantially seals the webbing, and a plurality of sockets secure to a plurality of casing throughbores. The webbing comprises a drive end plate secured to the central shaft with a bushing, an outboard end plate secured to the central shaft with a bushing, and a plurality of web socket supports aligned in two transversely aligned rows. The web socket plates each comprise two socket receiver channels for alignment with the sockets. Finally, a plurality of hammers releasably secure to the plurality of sockets.
