Claims20
An abrasive roll assembly, comprising:
- an abrasive roll element;
- an abrasive roll flange having a projecting member formed on its outer periphery and a plurality of through holes configured for mounting the abrasive roll flange to an adjacent flange, a plurality of projecting lugs formed on an upper portion of the abrasive roll flange, the lugs having a guiding and a resting portion, a plurality of projecting pads arranged with threaded holes for mounting the adjacent flange, and a plurality of guiding members circumferentially spaced apart each other to form a plurality of openings for entry and exit of the adjacent flange;
- and
- a supporting plate placed in opposite to the projecting member of the abrasive roll flange, such that the supporting plate is fastened to the abrasive roll flange using fasteners to secure and hold the abrasive roll element,
- wherein after inserting the abrasive roll assembly from bottom through openings of the adjacent flange, the abrasive roll assembly is rotated to make the resting portion of each projecting lug of the abrasive roll flange resting on the surface of each guiding member of the adjacent flange, such that each through hole of the abrasive roll flange is aligned with threaded hole in each projecting pad of the adjacent flange for mounting the abrasive roll assembly to the adjacent flange, which ensures center axial alignment of both the abrasive roll assembly and the adjacent flange with respect to a main shaft of a milling machine.

A conveyor assembly, comprising:
- an abrasive roll element;
- a conveyor flange assembled with a screw conveyor and coupled to a main shaft of a milling machine by means of locking nut, the conveyor flange is composed of a projecting member formed on its outer periphery, a plurality of projecting pads arranged with threaded holes for mounting an adjacent abrasive roll flange, and a plurality of guiding members circumferentially spaced apart each other to form a plurality of openings for entry and exit of the adjacent abrasive roll flange;
- and
- a supporting plate placed in opposite to the projecting member of the conveyor flange, such that the supporting plate is fastened to the conveyor flange using fasteners to secure and hold the abrasive roll element,
- wherein after inserting the adjacent abrasive roll flange from bottom through the openings of the conveyor flange, the adjacent abrasive roll flange is rotated to make each projecting lug of the adjacent abrasive roll flange resting on the surface of each guiding member of the conveyor flange, such that the threaded hole in each projecting pad of the conveyor flange is aligned with each through hole of the adjacent abrasive roll flange for mounting the adjacent abrasive roll flange to the conveyor flange, which ensures center axial alignment of both the conveyor flange and the adjacent abrasive roll flange with respect to the main shaft of the milling machine.
2 more elements
A vertical abrasive type milling machine, comprising:
- a bearing housing vertically mounted on a main structure of the milling machine;
- a main shaft rotatably supported in the bearing housing by means of upper and lower bearings, the main shaft is mounted to a machine pulley that is connected to a motor pulley by means of conveying belts;
- and
- at lease one conveyor assembly, comprising an abrasive roll element;
- a conveyor flange assembled with a screw conveyor and coupled to the main shaft by means of locking nut, the conveyor flange is composed of a projecting member formed on its outer periphery, a plurality of projecting pads arranged with threaded holes for mounting an adjacent abrasive roll flange, and a plurality of guiding members circumferentially spaced apart each other to form a plurality of openings for entry and exit of the adjacent abrasive roll flange;
- and a supporting plate placed in opposite to the projecting member of the conveyor flange, such that the supporting plate is fastened to the conveyor flange using fasteners to secure and hold the abrasive roll element, wherein after inserting the adjacent abrasive roll flange from bottom through the openings of the conveyor flange, the adjacent abrasive roll flange is rotated to make each projecting lug of the adjacent abrasive roll flange resting on the surface of each guiding member of the conveyor flange, such that the threaded hole in each projecting pad of the conveyor flange is aligned with each through hole of the adjacent abrasive roll flange for mounting the adjacent abrasive roll flange to the conveyor flange, which ensures center axial alignment of both the conveyor flange and the adjacent abrasive roll flange with respect to the main shaft of the milling machine;
- and
- one or more abrasive roll assemblies, each comprising an abrasive roll element;
- an abrasive roll flange that is composed of a projecting member formed on its outer periphery, a plurality of through holes configured for mounting the abrasive roll flange to an adjacent flange, a plurality of projecting lugs formed on its upper portion, with guiding and resting portions, a plurality of projecting pads arranged with threaded holes for mounting the adjacent flange, and a plurality of guiding members circumferentially spaced apart each other to form a plurality of openings for entry and exit of the adjacent flange;
- and a supporting plate placed in opposite to the projecting member of the abrasive roll flange, such that the supporting plate is fastened to the abrasive roll flange using fasteners to secure and hold the abrasive roll element, wherein after inserting the abrasive roll assembly from bottom through openings of the adjacent flange, the abrasive roll assembly is rotated to make the resting portion of each projecting lug of the abrasive roll flange resting on the surface of each guiding member of the adjacent flange, such that each through hole of the abrasive roll flange is aligned with threaded hole in each projecting pad of the adjacent flange for mounting the abrasive roll assembly to the adjacent flange, which ensures center axial alignment of both the abrasive roll assembly and the adjacent flange with respect to the main shaft of the milling machine.
