Mill for grinding garbage or the like

Device for combating material from wrapping around a shaft rotatable about an axis inside of a hollow chamber substantially larger than the shaft comprising, in combination:

• a multiplicity of wing plates;
• and means for mounting the wing plates orientated to extend generally radially from the shaft to a radial extent from the shaft substantially smaller than the chamber at circumferentially spaced locations around the shaft, with the radial extent of the wing plates effectively increasing the circumference of the shaft and the length of the material which could potentially wrap thereon, with each of the wing plates being formed by interconnecting two relatively shiftable plate members wherein each of the wing plates is selectively adjustable in length in a direction extending parallel to the shaft.

• wherein the wing plates each have an inner edge which abuts with the shaft to prevent material from wrapping around an individual wing plate.

• wherein the wing plates each have an outer edge of a decreasing radial size to predispose material which should wrap around the multiplicity of wing plates to migrate in the direction of the decreasing radial size.

• with the shaft including a rotor, with the rotor including a flat disc secured to and rotatable with the shaft and further including a multiplicity of arms each removably secured to the disc by at least first and second bolts extending through the arm at differing radial distances from the shaft, with the second bolt having lesser shear strength than the first bolt such that the arms are allowed to pivot about the first bolt in the event that the second bolt is sheared.
