Abstract: A dispenser includes a housing having an upper and a lower portion. The upper portion includes a storage compartment having a floor and retaining a granular substance. The lower portion includes a spout. A first outlet extends through the floor. A manually rotatable upper disc is disposed below the floor, and has a second outlet therethrough. A manually rotatable lower disc is disposed between the upper disc and the lower portion. The lower disc includes a third outlet therethrough. Rotation of the upper disc aligns the second outlet with the first outlet and the granular substance passes through the first to the second outlet. Rotation of the lower disc through one or more positions permits a variable amount of the granular substance to pass from the second to the third outlet. Further rotation of the lower disc aligns the third outlet with the spout to dispense the granular substance.

Abstract: 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°.

Abstract: 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 and a fastener securing the base and the tip to the hammer. The base includes a key having side walls extending upwardly from a surface of the base and spatially oriented as sides of a pyramid that is truncated before reaching their apex. The tip includes a keyway having side walls extending inwardly from a lower surface into a body of the tip and spatially oriented as sides of a pyramid. The keyway mates with the key of the base. The tip includes at least one, and preferably two, cutting edges disposed on opposing ends of the tip. In one embodiment, the tip is reversibly mountable to the base such that the cutting edges may be selectively used within grinding operations. In one embodiment, at least a portion of side walls of the truncated pyramid key and keyway are curved in a plane parallel to the surface of the base.
