Abstract
Abstract A high speed mixing machine in which power driven tools are arranged to rotate in a mixing vessel to produce a forced vortexlike movement of the material being mixed has a plurality of separate tools rotatable in coacting compartments of the vessel which merge with one another so that the material, particularly synthetic material to be processed and/or mixed e.g. with other material in the form of additives or liquids, is continuously transferred from one compartment to another of the vessel.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
165 words
A mixing machine having a mixer vessel, power-driven propeller-like tools extending adjacent to the vertical walls of said vessel and being operatively arranged to rotate about vertical axes in said mixer vessel at relatively high velocities and by centrifugal force produce a funnel-like movement in material being mixed in the vessel, the improvement comprising that the vessel is made up of a plurality of coacting vessels having merging cooperating mixing spaces, each being provided with its own mixer tools, the merging cooperating mixing spaces combining to form a common mixer space in which a continuous transfer of material from one cooperating mixing space thereof to another will occur on operation of the tools wherein said tools have a pitch which imparts to the material a component of axial movement and the tools of the cooperating vessels in each case consist of a set of several individual tools spaced apart and arranged coaxially one above the other, and being angularly offset in relation to one another.
Claim 2
Dependent Claim
165 words
A mixing machine having a mixer vessel, power-driven propeller-like tools extending adjacent to the vertical walls of said vessel and being operatively arranged to rotate about vertical axes in said mixer vessel at relatively high velocities and by centrifugal force produce a funnel-like movement in material being mixed in the vessel, the improvement comprising that the vessel is made up of a plurality of coacting vessels having merging cooperating mixing spaces, each being provided with its own mixer tools, the merging cooperating mixing spaces combining to form a common mixer space in which a continuous transfer of material from one cooperating mixing space thereof to another will occur on operation of the tools wherein said tools have a pitch which imparts to the material a component of axial movement and the tools of the cooperating vessels in each case consist of a set of several individual tools spaced apart and arranged coaxially one above the other, and being angularly offset in relation to one another.
Claim 3
Dependent Claim
17 words
A machine as claimed in claim 1, wherein the cooperating vessels are identical in size and shape.
Claim 4
Dependent Claim
23 words
A machine as claimed in claim 1, wherein the circumferences described by the outer extremities of the tools in adjacent cooperating vessels, overlap.
Claim 5
Dependent Claim
21 words
A machine as claimed in claim 1, the pitch of the tools being different in different ones of said cooperating vessels.
Claim 6
Dependent Claim
26 words
A machine as claimed in claim 1 wherein the direction of rotation of the tools in at least one of the cooperating vessels can be reversed.
Claim 7
Dependent Claim
25 words
A machine as claimed in claim 1, having a single inlet, for loading the overall vessel, which inlet opens into one of the cooperating vessels.
Claim 8
Dependent Claim
27 words
A machine as claimed in claim 1 having a single outlet, for the discharge of the overall vessel, which outlet opens from one of the cooperating vessels.
Claim 9
Dependent Claim
32 words
A machine as claimed in claim 1 wherein the mixing vessel is made up of two cooperating vessels and the tools are identical with one another, rotating synchronously in the same direction.
Claim 10
Dependent Claim
31 words
A machine as claimed in claim 1, wherein the mixing vessel is made up of two cooperating vessels and the tools are of mirror-symmetrical design, rotating synchronously but in opposite directions.
Claim 11
Dependent Claim
33 words
A machine as claimed in claim 1 wherein the floor levels of adjacent cooperating vessels are offset in relation to one another in the direction of the axes of rotation of the tools.
Claim 12
Dependent Claim
47 words
A machine as claimed in claim 10 wherein the degree of offset corresponds at least to the effective axial operating height of one of the individual tools rotating adjacent the floor, these tools themselves being axially offset in turn in accordance with the offset between the floors.
Claim 13
Dependent Claim
34 words
A machine as claimed in claim 10 wherein the direction of offset of the floors and of the individual tools adjacent the floors, corresponds with the direction of offset of the other individual tools.
Claim 14
Dependent Claim
33 words
A mixing machine as set forth in claim 1, in which said cooperating mixing spaces of said coacting vessels are mutually merging and the volumes of the mixing spaces differ from one another.
Claim 15
Dependent Claim
32 words
A mixing machine as set forth in claim 1, wherein a separate motor is operatively connected to each mixer tool and the speed of operation of each mixer tool is independently controllable.
