Abstract
Abstract A mixer system for granulated material, and the like, comprising a mixing chamber having a wall surface, plow means for moving material around the chamber including an edge portion movable across and in close proximity to the surface. Fluid dispenser means is provided for delivering coolant and lubricating fluid directly onto the edge portion of the plow means for cooling the same and reducing friction between the plow means and the chamber wall surface as well as for wetting the material. Control means is provided for controlling the time interval and/or flow rate that the dispenser means is operative for dispensing the fluid, thereby controlling the moisturization of the material in the mixing chamber.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
91 words
A mixer for granulated material and the like comprising a mixing chamber having a wall surface; plow means for moving material around said chamber including an edge portion movable across and in close proximity to said surface; and dispenser means for delivering coolant fluid onto said edge portion for cooling the same and wetting said material, said plow means including an advancing face traveling forwardly into said material and a back face, said dispensing means directing coolant fluid onto said back face in a forward direction along said lower edge portion.
Claim 2
Dependent Claim
91 words
A mixer for granulated material and the like comprising a mixing chamber having a wall surface; plow means for moving material around said chamber including an edge portion movable across and in close proximity to said surface; and dispenser means for delivering coolant fluid onto said edge portion for cooling the same and wetting said material, said plow means including an advancing face traveling forwardly into said material and a back face, said dispensing means directing coolant fluid onto said back face in a forward direction along said lower edge portion.
Claim 3
Dependent Claim
21 words
The mixer of claim 1 including control means for regulating the flow rate of coolant fluid delivered by said dispenser means.
Claim 4
Dependent Claim
40 words
The mixer of claim 1 including a mixing head mounted for rotation in said chamber about an axis normal to said surface and including arm means extending outwardly of said axis for supporting said plow means and said dispensing means.
Claim 5
Dependent Claim
75 words
The mixer of claim 3 wherein said chamber includes an upstanding sidewall parallel of said axis and spaced outwardly of and in close proximity to a circular path traversed by an end of said plow means, and liquid injector means for directing liquid into the material around at least a portion of said path for cooling the material and lubricating between said edge portion of said plow means and said wall surface of said chamber.
Claim 6
Dependent Claim
22 words
The mixer of claim 4 including liquid spray means above said chamber for cooling the upper surface of material in said chamber.
Claim 7
Dependent Claim
145 words
A mixer for granulated material and the like comprising a mixing chamber having a bottom wall and an upstanding sidewall; a mixing head in said chamber mounted for rotation about an upstanding axis for moving said material in a circular path around the chamber to mix the same; first water injector means on said sidewall for introducing cooling water into the material around at least a portion of the periphery of said circular path, second liquid injector means for introducing cooling water into the material from spaced locations on said bottom wall, third liquid injector means for introducing cooling water onto the upper surface of said material in said chamber, said mixing head including at least one plow having a lower edge movable in a circular path closely above said bottom wall and fourth liquid injector means for introducing cooling water along said lower edge.
Claim 8
Dependent Claim
145 words
A mixer for granulated material and the like comprising a mixing chamber having a bottom wall and an upstanding sidewall; a mixing head in said chamber mounted for rotation about an upstanding axis for moving said material in a circular path around the chamber to mix the same; first water injector means on said sidewall for introducing cooling water into the material around at least a portion of the periphery of said circular path, second liquid injector means for introducing cooling water into the material from spaced locations on said bottom wall, third liquid injector means for introducing cooling water onto the upper surface of said material in said chamber, said mixing head including at least one plow having a lower edge movable in a circular path closely above said bottom wall and fourth liquid injector means for introducing cooling water along said lower edge.
Claim 9
Dependent Claim
21 words
The mixer of claim 6 including automatic control means for operating said water injector means at preselected times and flow rates.
Claim 10
Dependent Claim
111 words
A mixer for granulated material and the like comprising a mixing chamber having an outlet for discharging material; door means movable to open and close said outlet; a mixing head including at least one plow means movable around said chamber for agitating said material; motor means for driving said mIxing head; liquid dispenser means for wetting material in said chamber and control means sensitive to the operative condition of said motor means for controlling said dispenser means to operate at selected times and rates, said control means includes first timer means for controlling said dispenser means to wet said material for a timed interval before said motor means is rendered operative.
Claim 11
Dependent Claim
111 words
A mixer for granulated material and the like comprising a mixing chamber having an outlet for discharging material; door means movable to open and close said outlet; a mixing head including at least one plow means movable around said chamber for agitating said material; motor means for driving said mIxing head; liquid dispenser means for wetting material in said chamber and control means sensitive to the operative condition of said motor means for controlling said dispenser means to operate at selected times and rates, said control means includes first timer means for controlling said dispenser means to wet said material for a timed interval before said motor means is rendered operative.
Claim 12
Dependent Claim
37 words
The mixer of claim 8 wherein said control means includes means for controlling said dispenser means to wet said material whenever the output of said motor means as sensed by said control means reaches a selected level.
Claim 13
Dependent Claim
33 words
The mixer of claim 8 wherein said control means includes second timer means for controlling said dispenser means to wet said material for a timed interval after said motor means is shut down.
