Abstract
A rotor for use in an impact crusher or in a hammer mill is assembled of two or more coaxial metallic discs having neighboring hubs and axially spaced apart radially outermost portions which define annular clearances for introduction of a welding implement. Such implement is used to apply annular welded seams which bond the ends of the hubs to each other. The welded seams are provided at the peripheral surfaces of the hubs. The hubs are mechanically coupled to each other by bolts prior to making of the welded seams. The radially outermost portions of the discs are thereupon connected with hammers or beater bars, depending on the intended use of the rotor.
Claims23
A rotor body for impact crushers or hammer mills comprising at least two coaxial steel casting discs having hubs with an axial length greater than the thickness of said discs and surpassing the discs at both sides, whereby the hubs of neighboring discs contact each other and are bonded to each other by annular welded seams, the axial length of the hubs is such, that neighboring discs or objects affixed to them before bonding the hubs define an annular clearance between the discs over the whole circumference which enables a welding implement to roundabout reach said hubs.
A rotor for impact crushers or hammer mills comprising a metallic rotor for comminuting having at least two coaxial metallic discs formed as weldable metalic disks and having neighboring hubs;
- and annular welded seams bonding said hubs to each other.
A rotor for impact crushers or hammer mills comprising at least two coaxial steel casting discs having hubs with an axial length greater than the thickness of said discs and surpassing the discs at both sides, whereby the hubs of neighboring discs contact each other and are bonded to each other by annular welded seams, the axial length of the hubs is such, that neighboring discs or objects affixed to them before bonding the hubs define an annular clearance between the discs over the whole circumference which enables a welding implement to roundabout reach said hubs.
