Patent ID: 7785033

Claim:
An apparatus for fragmenting and re-mixing rubberized asphalt material containing agglomerated pieces, comprising: a. an auger and tine assembly having a first helical auger section and a second helical auger section, both said first and second sections having top portions and opposing inner portions and being mounted in spaced relation over respective ends of a rotatable drive shaft, a rotating tine section having a top portion and being mounted on said drive shaft between said inner portions, said first and second auger sections further being of converging, opposite handedness, so as to advance material and the agglomerated pieces inwardly toward said rotating tine section; b. an auger and tine housing having an upper portion with a material inlet and a lower portion with a material discharge, said housing further having a first endwall and a second endwall, said auger and tine assembly being mounted for rotation within said lower portion between said first and second endwalls, and a fixed tine section being mounted in said housing in interdigitized relation with said rotating tine section, said material discharge being located below said fixed tine section, said housing substantially surrounding said first and second auger sections and said rotating and fixed tine sections, but leaving said top portions of said first and second auger sections and said rotating tine section exposed to said material inlet, said housing further including a fragmenting and re-mixing zone the fragmenting and re-mixing zone includes a plurality of fixed tines arranged in interdigitized relation with a plurality of rotating tines adjacent and around said rotating and fixed tine sections; c. drive means for rotating said auger and tine assembly, whereby agglomerated pieces and material entering said material inlet are advanced and deposited onto said rotating tine section and said fixed tine section in said fragmenting and re-mixing zone, wherein agglomerated pieces are fragmented and re-mixed with asphalt material before passing through said material discharge.
