Abstract
An improvement for pellet mills for resolving the radial forces which develop between the die and the rollers. An extension is provided on the main shaft extending beyond the roller support frame arms, and a bearing assembly is mounted on the extension for supporting a spider connected to the die cover.
Claims8
In a pellet mill comprising a base, a die housing mounted on said base, an annular die and die cover secured to said die housing, said die housing, die and die cover defining a pelleting chamber therewithin, a main shaft supported concentrically within said die housing and extending into said pelleting chamber, a roller support frame extending from said main shaft, a plurality of rollers rotatably supported on said roller support frame in contiguous cooperative relation with said die, means on said die housing and main shaft providing relative rotation of said die housing, die and die cover with respect to said main shaft, roller support frame and rollers, means adjacent said die cover for conveying material to be pelleted into said pelleting chamber, and means on said roller support frame for directing material to be pelleted into the nips of said rollers, the improvement comprising means for resolving the radial forces developed between said rollers and said die during pelleting operations, said latter means comprising an extension of said main shaft beyond said roller support frame, support means extending between said die cover and said main shaft extension and including bearing means permitting relative rotation of said die cover and said main shaft extension, said support means being apertured to permit the passage of material to be pelletized therethrough.
In a pellet mill comprising a base, a die housing mounted on said base, an annular die and die cover secured to said die housing, said die housing, die and die cover extending in cantilevered relation to said base and defining a pelleting chamber therewithin, a main shaft supported concentrically within said die housing and extending into said pelleting chamber, a roller support frame extending from said main shaft, a plurality of rollers rotatably supported on said roller support frame in contiguous cooperative relation with said die, means on said die housing and main shaft providing relative rotation of said die housing, die and die cover with respect to said main shaft, roller support frame and rollers, means adjacent said die cover for conveying material to be pelleted into said pelleting chamber, and means on said roller support frame for directing material to be pelleted into the nips of said rollers, the improvement comprising means for resolving the radial forces developed between said rollers and said die during pelleting operations, said latter means comprising an extension of said main shaft beyond said roller support frame, bearing means on said main shaft extension, and support means extending between said die cover and said main shaft extension bearing means, said support means being apertured to permit the passage of material to be pelletized therethrough.
In a pellet mill comprising a base, a die housing rotatably mounted on said base, an annular die and die cover secured to said die housing for rotation therewith, said die housing, die and die cover extending in cantilevered relation to said base and defining a pelleting chamber therewithin, a stationary main shaft supported concentrically within said die housing and extending into said pelleting chamber, a roller support frame extending from said main shaft, a plurality of rollers rotatably supported on said roller support frame in contiguous cooperative relation with said die, means adjacent said die cover for conveying material to be pelleted into said pelleting chamber, and means on said roller support frame for directing material to be pelleted into the nips of said rollers, the improvement comprising means for resolving the radial forces developed between said rollers and said die during pelleting operations, said latter means comprising an extension of said main shaft beyond said roller support frame, bearing means on said main shaft extension, and support means extending between said die cover and said main shaft extension bearing means, said support means being apertured to permit the passage of material to be pelletized therethrough.
