Abstract
A hammermill is presented which includes a plurality of hammers each presenting an arcuate striking profile. The hammermill includes a rotor having rods for swingable carrying the hammers thereon and a motor for rotating the rotor. The hammers are longitudinally spaced along the rotor and preferably helically arrayed thereabout. The hammers present a head and a body, the head having an arcuate striking face which may include a point. As the rotor turns, the hammers are free to swing on the rods and comminute material fed into the hammermill. The hammers preferably present symmetrical striking profiles whereby after one profile becomes worn, the position of the hammer on the rod may be reversed to increase the useful life thereof.
Claims9
A hammermill for comminuting material received therein comprising:
- means for supporting a plurality of hammers such that each hammer rotates in a plane about a longitudinal axis;
- drive means for rotating said hammer support means about said longitudinal axis;
- a plurality of hammers, each hammer being formed to include a proximate end and a remote end, the remote end being shaped as a modified right cylinder, the right cylinder having a curved surface on each of two opposing sides of the right cylinder, the two opposing curved sides being joined by substantially flat surfaces, each flat surface being parallel to a diameter of the right cylinder, the diameter bisecting a midpoint of each of the two opposing curved sides of the right cylinder;
- and
- means coupling said plurality of hammers to said support means at circumferentially spaced intervals thereabout whereby said hammers extend radially outward from said hammer supporting means during rotation thereof,
- each of said hammers presenting the curved surfaces thereon for engaging the material to be comminuted.
