Patent number: 5829692Abstract: A modularly tiered clear-trajectory impact commuter apparatus that comminutes rock, drilling materials and other comminutable by impact rather than by grinding or crushing. The invention creates a comminution environment which maximizes the establishment of a clear essentially tangential trajectory for the material between the orbit of each spinning blade and a single rectangular breaker bar. The modular vertical series coupling of the modularly tiered clear-trajectory impact comminuter apparatus may be adjusted to accommodate the material throughput for any environment whereby, for any given size of comminution chamber and rotary blade configuration, any number of tierable, modular comminution chambers may be vertically tiered for achieving the desired material throughput in relation to the load of comminutable material.Type: GrantFiled: January 17, 1997Date of Patent: November 3, 1998Assignee: Wildcat Services Inc.Inventor: Jerry Wayne Walters

Patent number: 5820044Abstract: A solid material pulverizer using a vertical shaft has a plurality of bearings above a lower fixed bearing that are resiliently held in fixed mounts allowing the bearings to rise vertically against spring pressure as the shaft lengthens from thermal expansion. Impellers fixed to the shaft between the bearings hurl solid material against rings arranged around the impellers, and the rings have multi-sided interiors with ridges and grooves confronting the impeller and angled inward from bottom to top of each ring.Type: GrantFiled: April 25, 1997Date of Patent: October 13, 1998Inventor: Guido Greco

Patent number: 5775604Abstract: Glassware such as glass bottles and the like is crushed, graded, screened and collected in accordance with the size of the crushed glass. Glassware such as glass bottles is supplied to a glassware charging frame passed to a first crusher and crushed by the first crusher. Metal is removed from the glassware crushed by the first crusher. The thus crushed glassware with iron pieces having been removed is supplied to a last crusher. Glassware crushed by the last crusher is supplied to a sieve device. The glassware crushed by the last crusher is selected in accordance with grain size by the sieve device. The glassware selected in accordance with grain size then is collected.Type: GrantFiled: March 10, 1997Date of Patent: July 7, 1998Assignees: Kaneto Co., Ltd., Kankyohozenservice Co., Ltd.Inventor: Koithi Sato

Patent number: 5732894Abstract: A micronizer includes a housing having a chamber in which a vertical array of impeller discs is disposed. Impact members are disposed on the impeller discs. One, or more, of the impellers have impact members that overhang circular peripheral edges of the impeller discs. The rotational speed of the array of impeller discs may be varied by adjusting the speed of a variable drive motor. The rate of air flow through the array of impeller discs may be varied by adjusting the speed of a fan, which is independent of the speed of the array drive. A plurality of air deflector plates mechanically cause downward force vectors to deflect a combined pulverulent air-material mixture downwardly toward said rotating impact members.Type: GrantFiled: November 9, 1995Date of Patent: March 31, 1998Inventor: Richard T. Sheahan

Patent number: 5685500Abstract: A mill (10) for grinding garbage or like material is disclosed including grinding rotors (48-50) rotatably fixed to and longitudinally adjustable on a shaft (44) rotatable in a grinding chamber (26). Each of the rotors (48-50) include a multiplicity of arms (64) extending radially from a circular disc (54). The arms (64) have replaceable tips (284) including first and second legs (288, 290) forming an L-shaped body portion. First and second bolts (308) extend through apertures (310) in the arm (64) and are threaded into apertures (312) in the first leg (288). A third bolt (314) extends through a counterbore (320) and an aperture (316) in the second leg (290) and is threaded into aperture (318) of the radially outer end of the arm (64). Material anti-wrap provisions (140) in the form of wing plates (240) oriented to extend generally radially from the shaft (44) are provided between the top plate (28) and the first rotor (28) and also between the rotors (48-50).Type: GrantFiled: October 3, 1994Date of Patent: November 11, 1997Assignee: Wastenot International Ltd.Inventors: Eric P. Eide, Russel L. Eide, II

Patent number: 5680994Abstract: A mill (10) for grinding garbage is disclosed including an octagonal shaped grinding chamber (26). Grinding rotors (48-50) are rotatably fixed to a rotatable shaft (44). An impeller rotor (51) is also rotatably fixed to the shaft (44) below the grinding rotors (48-50). The impeller rotor (51) discharges a stream of air, entrapped material, and projectiles into a projectile deflection device (182) which includes an upwardly sloping bottom plate (202) which deflects the projectiles into an end plate (204) to reduce the kinetic energy thereof. The air stream and entrapped material pass from the projectile deflection device (182) into a plenum (210) which reduces the velocity of the air stream to release much of the entrapped material, with the material release being enhanced by baffles (224) providing a tortuous path for the air stream in the plenum (210) before it enters a cyclonic material separator (216).Type: GrantFiled: April 26, 1993Date of Patent: October 28, 1997Assignee: Wastenot International Ltd.Inventors: Russel L. Eide, Eric P. Eide, Russel L. Eide, II

Patent number: 5544820Abstract: This invention relates to an apparatus for comminuting rock and other material and, in particular, to a rotary driven blade apparatus which comminutes rock, drilling materials and other material by impact rather than by grinding or crushing. More particularly, the invention creates a comminution environment which maximizes the establishment of a clear trajectory for the material between the orbit of each spinning blade and a single breaker bar.Type: GrantFiled: February 21, 1995Date of Patent: August 13, 1996Inventor: Jerry W.

Patent number: 5495796Abstract: Spiny pads are centrifugally propelled in a spiralling-outward pathway by a plurality of fingers that swing around a cylindrical chamber from a concentric shaft. The interior surface of the chamber is partially lined with spine shearers such as a rasp, so that the pads scrape against the rasp and thereby are despined. Spine pieces leave the chamber through small perforations in the chamber wall.Type: GrantFiled: February 22, 1994Date of Patent: March 5, 1996Inventor: Dennis M. Mueller
