FIELD: food industry, tobacco. ^ SUBSTANCE: tobacco crumber has a HP chamber that, in its turn, has an inlet hole for tobacco raw material on the LP side, an outlet hole with a clearance for thermal expansion on the HP side and a shaft-mounted auger conveyor for tobacco raw material transportation from the inlet hole to the outlet hole. The auger conveyor shaft is mounted on the inlet hole side and passes behind the outlet hole where it is equipped with one more support represented by a counter-bearing. The outlet hole with a clearance has the first outlet hole part attached to the HP chamber or to the outlet manifold and the second outlet hole part mounted on the shaft so that to be capable of rotation synchronously with it. For the clearance size adjustment the second outlet hole part may axially be locked in different positions on the auger conveyor shaft. Additionally, the invention deals with a tobacco crumbing method envisaging transportation of tobacco raw material from the inlet hole to the outlet hole with the help of the auger conveyor the both end parts whereof are mounted on the shaft whose operational rate may be as much as 600 min-1. ^ EFFECT: invention enables reliable operation of the device in any operation mode, reducing the shaft wear and increasing tobacco raw material passage rate. ^ 13 cl, 2 dwg

Thermoplastic resin plasticising/compressing machine

Reduction gear for the screw of a machine for plasticising and compressing thermoplastic resins is flanged on the screw cylinder, while the driving axle of the reduction gear is connected with the driven end of the screw by coupling elements, which can be withdrawn, centrally hold the end of the screw, and have forces for transferring axial power, and the driving axle terminates against the housing of the reduction gear over the bearing receiving the axial force of the screw. The reduction gear has a relatively short overall length, and can be easily dismantled, inspected, cleared or replaced, and re-assembled.

Thrust distribution levers for extruder screw bearings - to minimise sepn. or maximise thrust for multiscren machines

In the support of a series thrust bearing mounted along a rotating shaft and riding on stationary bearing tracks mounted on a corresp. series of support plates, the mutual alignment and load-sharing of the support plates is ensured by pairs of rods mounted on a stack of balanced levers supported on opposite sides of an ancillary thrust plate. The plates are keyed against rotation by an adjacent rod. Alternatively, the thrust is transmitted down the root of the shaft via a series of split collars, each of which divides the thrust between the adjacent rotary bearing and the next stage of the shaft root by a ratio depending on the relative differences in the radial spacing of bearing rods on support faces of the collars from road acting as a fulcrum on the thrust faces of the collars. Used for supporting the thrust of screws for e.g. extrusion of plastics or rubber materials, esp. of multi screw machines with limited space between adjacent screw axes. Automatic thrust equalisation prevents ...

Screw press with radial gate valve and supported screw shaft

NEW ABSTRACT A screw press is having a radial gate valve and supported longitudinally-extending screw shaft. The screw shaft includes a central shaft and helical threads which is driven by a drive package. The screw shaft is encapsulated within a housing including a hopper portion, transition portion, bearing portion and screen portion. A transition portion includes a radial gate valve which is angled such that the radial gate valve's axis of rotation is substantially parallel to the screw shaft threads. In addition, the screw shaft is supported by a first support at its proximal extremity and a second support towards its distal extremity. The support at its distal extremity includes one or more wear bearings which concentrically support the threads of the screw shaft in a frictional engagement manner. The angle of the radial gate valve with respect to the screw presses housing provides for greater pressure build up within the screen portion. Moreover, the use of wear bearings reduces wear to the housing and screen due to metal on metal contact with the screw threads and also provid for increased efficiency of the screw press operation.
