Homogenizing and/or dispersing device comprising endless screws
First Claim
1. An apparatus for at least one of homogenizing and dispersing at least one viscous substance provided in combination with at least one solid or at least one other substance of different viscosity, having at least three axis-parallel rotatable shafts disposed in a screw space in a housing along a circle with equal central-angle distance and provided at least partly with tightly intermeshing screw elements, the housing being provided on the radially external and internal sides of the screw space with axis-parallel concave circular segments receiving the particular shaft and with openings into the screw space, wherein the shafts are provided in the area outside the openings over a length (L=L1+L2+L3) corresponding to at least ten times the outside screw diameter (D) of the screw elements with the screw elements having a pitch (S) of at most three quarters of the outside screw diameter (D) over a length of at least three times the outside diameter (D) of the screw elements.

Abstract
An apparatus for homogenizing and/or dispersing at least one viscous substance and at least one solid and/or at least one other substance of different viscosity includes in a space in a housing axis-parallel rotatable shafts disposed along a circle with equal central-angle distance and provided with tightly intermeshing screw elements. The shafts in the area outside the openings in the housing are provided with screw elements having a pitch (S) of at most three quarters of the outside screw diameter (D) over a length (L=L1+L2+L3) corresponding to at least ten times the outside diameter (D) of the screw elements.

9. An apparatus for homogenizing and dispersing a viscous substance and at least one of solids and another viscous substance of different viscosity, comprising:
-
a cylindrical housing, including axial parallel concave circular segments defined by wedges therebetween, said cylindrical housing including a first opening at a first end for receiving the viscous substance and the at least one of solids and another viscous substance of different viscosity, and a second opening at a second output end; an inside core in the housing including axis parallel concave circular segments defined by wedges therebetween, the inside core having the same number of corresponding axis parallel concave circular segments as the cylindrical housing, wherein the housing and inside core define an annular screw space; and at least three axis-parallel rotatable shafts disposed in the annular screw space along a circle with equal central-angle distance, each said shaft received in corresponding ones of said concave circular segments of the housing and the inside core, the rotatable shafts being provided with tightly intermeshing screw elements having an outside screw diameter (D), the shafts having a length of at least ten times the outside screw diameter (D), the screw elements having a pitch (S) of at most three quarters of the outside screw diameter (D) over a length of at least three times the outside screw diameter (D), wherein said rotatable shafts are rotated in the same direction and said apparatus is free of kneading blocks. - View Dependent Claims (10, 11, 12, 13, 14)

15. An apparatus for homogenizing and dispersing a viscous substance and at least one of solids and another viscous substance of different viscosity, comprising:
-
a cylindrical housing, including axial parallel concave segments defined by wedges therebetween, said cylindrical housing including a first opening at a first end for receiving the viscous substance and the at least one of solids and another viscous substance of different viscosity, and a second opening at a second output end; an elongate inside core in the housing including axis parallel concave segments defined by wedges therebetween, the inside core having the same number of axis parallel concave segments as the cylindrical housing, wherein the housing and inside core define an annular screw space extending about the inside core; and at least three axis-parallel rotatable shafts disposed in the annular screw space along a circle with equal central-angle distance, each said shaft received in corresponding ones of said concave circular segments of the housing and the inner core, the rotatable shafts being provided with tightly intermeshing screw elements having an outside screw diameter (D), the shafts having a length of at least ten times the outside screw diameter (D), the screw elements all having a pitch (S) of at most three quarters of the outside screw diameter (D), the screw elements extending along the length of the entire portion of each said rotatable shaft that processes the viscous substance and the at least one of solids and another viscous substance of different viscosity, wherein said shafts are rotated in the same direction. - View Dependent Claims (16, 17, 18)
