An improved free swinging hammer mill hammer design is disclosed and described for comminution of materials such as grain and refuse. The hammer design of the present art is adaptable to most hammer mill or grinders having free swinging systems. The improved hammermill hammer may incorporate multiple comminution edges for increased comminution efficiencies. The improved hammermill hammer may incorporate multiple comminution edges for having increased hardness for longer operational run times. The design as disclosed and claimed may be forged to increase the strength of the hammer. The shape of the hammer body may be varied, as disclosed and claimed, to improve the hammer strength reduce or maintain the weight of the hammer while increasing the amount of force delivered to the material to be comminuted. The improved design may also incorporate comminution edges having increased hardness for longer operational run times.

A plurality of chipper inserts that may be installed on a hammermill rotor in place of the hammer inserts to selectively convert the rotor to a chipper. The chipper inserts include drum surfaces that cooperatively define a chipper drum. The chipper inserts may include cutter inserts that have a cutter disposed in a cutter pocket. The chipper drum may be a generally continuous cylindrical interrupted essentially only by the cutter pockets. The cutters and cutter pockets may be positioned in essentially any desired pattern around the drum. The chipper inserts may include a left cutter insert, a center cutter insert, a right cutter insert and three different size spacer inserts. The different types of cutter inserts and spacer inserts may be installed about the rotor with at least one left cutter insert mounted on the left end of the chipper drum and at least one right cutter insert mounted on the right end of the chipper drum. The chipper inserts may be configured in quadrant sections, such that it takes four inserts to extend around the rotor.

The various embodiments disclosed and pictured illustrate a curved hammer for comminuting various materials. The illustrative embodiments pictured and described herein are primarily for use with a rotatable hammermill assembly. The curved hammer includes a connection portion having a rod hole therein, a contact portion for delivery of energy to the material to be comminuted, and a curved neck portion affixing the connection portion to the contact portion. In other embodiments, a shoulder is positioned around the periphery of the rod hole for added strength. In still other embodiments, a neck reinforcement is positioned along a portion of the neck for increased strength. A weld or plurality of welds may be affixed to various surfaces of the contact portion to aide in comminuting and / or longevity of the curved hammer.

The present invention provides both a process and apparatus for treating tubers in storage with chlorpropham (CIPC) dust or the dust of any other similar organic compound. The process includes the steps of forming minute particles of solid CIPC particles from a larger block or chunks of solid CIPC, and inducting the particles into an airstream which transports the particles to a tuber storage shed. For a preferred embodiment of the invention, the blocks or chunks of solid CIPC are fed into a hammer mill or like apparatus, which pulverizes the solid CIPC. Insufficiently fine particles are returned to the mill for further pulverization. Fine powder consisting of particles, each of which has a major dimension of less than about 5 micrometers, is transported by the ducted airstream from the separator to a storage shed containing a pile of tubers. The powder filters through the pile and coats exposed surfaces of the exposed tubers.

A screening machine on a frame with a hopper having a conveyor belt. The conveyor belt discharges particulate material poured into the hopper into a rotating barrel screen or vibrating planar screen for sifting the material. A hammermill apparatus is pivotably mounted on a hood member to an arm that is pivotably mounted to the frame of the machine. The hammermill is positioned above the conveyor belt at the discharge end. The hammermill can pivot upwardly relative to the arm upon striking a large object on the conveyor belt, and a spring mounted to the arm and the hood biases the hammermill back to its original position. A hydraulic ram is drivingly linked to the arm for manually or automatically displacing the hammermill relative to the conveyor belt.

A hammermill having a housing, a rotor assembly, a plurality of hammers, and a attrition plate assembly is provided to reduce oversized particulate material to a desired size. The housing has a sidewall that extends between an inlet end and an discharge end which defines an enclosed work space. The rotor assembly is disposed within the housing for rotation about a longitudinal axis of the housing. The plurality of hammers is coupled to the rotor assembly and is disposed within the enclosed work space. The attrition plate assembly has a generally circular configuration and is removably secured to the sidewall within the enclosed work space of the housing. The attrition plate assembly is arranged such that a portion of at least one hammer of the plurality of hammers is spaced from and overlies a portion of the first attrition plate assembly so that the at least one hammer and the attrition plate assembly cooperate to reduce particulate material to a desired size and to urge the particulate material toward the discharge end of the housing.
