Patent number: 4702746Abstract: A system for converting selected commercially or industrially derived waste materials in a generally dry and friable form, into a pelleted fuel product, comprising an input conveyor (10), a primary breaker (11) for breaking and reducing the incoming materials, a levelling drum (38), a magnetic drum (43) for extracting ferrous objects from the stream of materials, a shredder (16) from which shredded, cut and screened materials are directed by an air stream into a collecting bin (18) from which they are fed to a densifier (21) which creates a denser stream of materials to be fed to a pelleting press (22) from which the pelleted fuel product is taken via output conveyor (23).Type: GrantFiled: January 23, 1986Date of Patent: October 27, 1987Assignees: Simon-Barron Limited, Henley Burrowes & Co. Ltd.Inventor: Maurice Finch

Patent number: 4316713Abstract: An annular die for a pelletizing machine, having a multiplicity of radial bores (12) through which in one direction or the other, material is extruded to form pellets, each radial bore (12) having a portion (A) of constant cross-sectional area and a portion (B) of gradually increasing cross-sectional area, the latter extending to the peripheral surface (14) of the die to which material to be extruded is supplied, the transition between the portion (B) of increasing cross-sectional area and the portion (A) of constant cross-sectional area being entirely smooth such that there is no break in the profile of the internal wall surface of the bore (12).Type: GrantFiled: November 7, 1979Date of Patent: February 23, 1982Assignee: Simon-Barron LimitedInventor: Stanley Trickett

Patent number: 4134552Abstract: A grinding mill of the kind comprising a generally cylindrical grinding chamber defined by a screen having a shaft supporting a plurality of grinding hammers rotatable therein and being enclosed in a chamber to which suction is applied characterized by the provision of instrumentality for sensing the pressure within the enclosure surrounding the screen and actuating a safety device in the event that the pressure falls below a pre-determined value.Type: GrantFiled: September 12, 1977Date of Patent: January 16, 1979Assignee: Simon-Barron LimitedInventors: Stewart P. T. Fraser, Paul A. Fellowes-Freeman

Patent number: 3950120Abstract: A pelletising machine of the kind comprising an annular die having radial bores therethrough, and adapted to be rotated about its central axis, whereby material introduced into the centre of the die is extruded through the bores by the action of freely rotatable pelletising rollers which are closely spaced from the inner peripheral surface of the annular die, and having a door which can be hinged between an open position enclosing the die, there being a cut-off knife mounted on the end of a shaft extending through the wall of said door, characterised in that the shaft supporting the cut-off knife passes through a guide sleeve carried in a housing secured to the wall of the door, there being means to permit fine adjustment of the position of said shaft axially within said guide sleeve and means permitting said guide sleeve together with said shaft to be moved as a unit rapidly outwardly relative to said housing and returned inwardly to their initial position.Type: GrantFiled: November 22, 1974Date of Patent: April 13, 1976Assignee: Simon-Barron LimitedInventors: Herbert Jones, Michael Thomas Dorn
