The utility model is high speed shear homogenizing mill, the mill body that mainly comprises band charging aperture and bleeder valve, place fixed millstone and movable grinding disc in the mill body, it is 100-140 ° taper shape that the corresponding flour milling that it is characterized in that described fixed millstone and movable grinding disc is angle α, also is respectively equipped with in correspondence with each other cutter tooth circle and cutter tooth on the flour milling.During use, preceding working procedure is with the asphalt base-material heating and melting and add graininess or the polymer modifiers of sheet, stir into mixed slurry through swelling, enter mill chamber by charging aperture, in the conical flour milling gap of movable grinding disc and fixed millstone correspondence, relative motion along with the movable grinding disc of at a high speed rotation and static fixed millstone, mixed slurry is under the drive of movable grinding disc, be subjected to the cutter tooth circle arranged in a crossed manner on the conical flour milling and the shear action of cutter tooth, both made circular motion along flour milling, under centrifugal action, do radial motion again, and vortex flow and line that fierceness takes place in the groove of cutter tooth flow, make polymer modifiers the replacing in the mixed slurry at movable grinding disc and fixed millstone cutter tooth in correspondence with each other, continuous high speed is sheared down by the height dispersion and fining, and be evenly dispersed in the asphalt base-material, become the modified pitch slurry, the modified pitch slurry after refinement and the homogenizing flows out through bleeder valve and enters down the road manufacturing procedure.
Also can be provided with the corresponding flange flour milling of planar shaped on the flange of described fixed millstone and movable grinding disc, also be respectively equipped with the cutter tooth circle on the flange flour milling, the flow direction and guiding that the flange flour milling of planar shaped both can change the modified pitch slurry are flowed out to bleeder valve, also can make slurry in the outflow shearing homogenizing that takes a step forward; The cross section of cutter tooth is the ∩ font on the conical flour milling, to increase the cutter meeting, improves shear effect.
For realizing better high speed shear homo-effect, the utility model also can comprise and to link to each other with fixed millstone, by the governor motion that handle, handwheel, worm screw, worm gear constitute, can be according to the refinement of mixed slurry and the clearance distance between homogenizing requirement adjusting fixed millstone and the movable grinding disc flour milling; Also can be provided with pay-off between described charging aperture and the fixed millstone; The external conduction oil annular groove that also is provided with of described mill for the homogenizing mill provides required homogenization temperature when working, and is controlled.
The utility model is reasonable in design, fixed, the conical structure of the corresponding flour milling of movable grinding disc and the reasonable setting of cutter tooth circle and cutter tooth, act on toughness material with high speed shear, the height refinement and the homogenizing of slurry have been realized effectively, the fineness of polymer can reach micron order in the refinement disposed slurry, make polymer modifiers through the refinement of homogenizing mill height and be evenly dispersed in the asphalt base-material, thereby make the intrinsic separately excellent properties of polymer and pitch in polymer modified asphalt organically in conjunction with and demonstrate fully, can improve the high temperature viscosity of modified pitch effectively, low-temperature ductility and elasticity, improve anti-aging and adhesiveness, strengthen ability of anti-deformation and anti-crack ability.The utility model is easy to operate, is applicable to processing and manufacturing to modified pitch such as polymer.
