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 multi-piece hammer for use in a reducing machine. The multi-piece hammer includes a base to be mounted to the reducing machine, a replaceable tip to be mounted to the base and to impact the material to be reduced, and a retainer to secure the replaceable tip to the base. The replaceable tip has a cavity with a single rail or groove that corresponds to a single groove or rail on the base.

A cutter assembly is presented for mounting to one or more hammers of a rotor assembly of a grinding machine. The cutter assembly includes a base, a tip mount, at least one cutting edge and a wedge releasably secured to the tip mount, and a fastener securing the base and the tip mount to the hammer. The base includes a truncated pyramid key and the tip mount includes a corresponding truncated pyramid keyway. A wedge edge angle is defined between a wedge top face and side face. A cutting edge angle is defined between a cutting edge knife face and top face. The cutting edge angle can be larger than the wedge edge angle. The cutting edge angle can be in the range of about 30 to about 40 and a wedge edge angle can be in the range of about 40 to about 45.

An impact crusher hammer comprises a hammer shaft sleeve sleeved and mounted on a roll shaft of the impact crusher using a shaft hole. A cubic hammer body is connected above the hammer shaft sleeve through a journal. Both the front working surface and the top working surface of the hammer body are provided with two kinds of different sized elliptic cylindrical hard alloys that are evenly alternated. The elliptic cylindrical hard alloys are deeply embedded into and firmly welded with corresponding deep holes opened on the front working surface and the top working surface of the hammer body; a large area of hard welding rods is welded on two side surfaces of the hammer body corresponding to the front working surface and the top working surface of the hammer body.

A top wear plate for the rotor of a rock crusher, wherein the rotor includes a rotor body, the rotor body having an upper surface. The top plate includes a lip positioned about and descending vertically from the underside of the outer circumference of the lip wear plate, the lip including a protrusion to engage with a complementary recess on the top surface of the rotor body.

A rotor protection plate for mounting on an upper plate of a rotor body of a crusher, in particular a vertical shaft impact crusher, is provided. The rotor protection plate comprises a body having an inner face defining a guide slot that is operably arranged to be in register with a rotor tip block opening defined on the upper plate of the rotor body and spaced apart therefrom to allow for a rotor tip block to be partly inserted into the guide slot during removal of the rotor tip block from, or insertion of the rotor tip block into, the rotor body.

A cutter assembly is presented for mounting to one or more hammers of a rotor assembly of a grinding machine. The cutter assembly includes a base, a tip mount, at least one cutting edge and a wedge releasably secured to the tip mount, and a fastener securing the base and the tip mount to the hammer. The base includes a truncated pyramid key and the tip mount includes a corresponding truncated pyramid keyway. A wedge edge angle is defined between a wedge top face and side face. A cutting edge angle is defined between a cutting edge knife face and top face. The cutting edge angle can be larger than the wedge edge angle. The cutting edge angle can be in the range of about 30 to about 40 and a wedge edge angle can be in the range of about 40 to about 45.
