Description: |
| Application filed in the United Kingdom, 27 Feb., 1980.
Abstract:
A mill, particularly a mill for extracting juice from cane sugar, has a fixed top roller and feed discharge rollers and which are independently pivotable by respective power operated means to vary the feed opening between the feed roller and top roller and the discharge opening between discharge roller and top roller. A trash plate for transferring material between the feed opening and the discharge opening is connected to the feed roller for pivotable movement therewith.
Claim:
A mill comprising a feed roller, a top roller, and a discharge roller, housing means defining a center plane and including two upstanding spaced frames between which said rollers extend, the axes of the rollers being parallel to each other, first bearing means at opposite ends of the top roller and carried respectively by the two upstanding frames, second bearing means at opposite ends of the feed roller, first chair means operatively mounted in said housing means and supporting said second bearing means for pivotable movement of said feed roller about a first pivot axis defined by said first chair means, operatively mounted first power operated means coupled to said first chair means for varying the feed opening between the feed roller and the top roller, third bearing means at opposite ends of the discharge roller, second chair means operatively mounted in said housing means and supporting said third bearing means for pivotable movement of said discharge roller about a second pivot axis defined by said second chair means, operatively mounted second power operated means coupled to said second chair means for varying the discharge opening between the discharge roller and the top roller, trash plate means for transferring material between the feed opening and the discharge opening, said trash plate means being disposed between the feed and discharge rollers and being coupled to said first chair means for movement therewith, said first and second pivot axes defined respectively by said first and second chair means being disposed adjacent to said center plane of the mill, said first pivot axis for said feed roller means being disposed on the discharge side of said center plane and in a plane parallel to the center plane and passing through or substantially passing through a heel of said trash plate means, the mill being structured such that mill settings are automatically adjusted according to throughput and quality of throughput by constant pressures applied respectively to said feed roller and to said discharge roller by said first and second power operated means and such that the ratio between the feed and discharge openings is maintained substantially constant for all conditions of feed. |
